ISO/IEC TS 17035:2024 - Conformity assessment — Guidelines for validation and verification programmes
Overview
ISO/IEC TS 17035:2024 - Conformity assessment - Guidelines for validation and verification programmes (Technical Specification, first edition) provides practical guidance for developing, operating and recognising validation/verification programmes. Designed to be used alongside ISO/IEC 17029, this TS clarifies programme content, governance and processes for bodies that issue validation statements or verification statements and for programme owners, regulators and other interested parties.
Key topics
The document organises guidance around programme design and operation, including:
Programme content
- Scope of validation/verification: definition and boundaries of claims to be validated or verified.
- Competence and impartiality: expectations for validation/verification bodies and personnel.
- Operational steps: recommended steps for planning and executing validation and verification activities.
- Evidence gathering activities: how bodies should collect, assess and use objective evidence (historical data for verification; projected data for validation).
- Reporting: structure and purpose of validation/verification statements and reports.
Programme development
- Guidance for creating rules, procedures and management systems for sector-specific or cross-sector programmes.
Programme maintenance and recognition
- Requirements for ongoing review, improvement and the process to recognise programmes (including informative annexes on logos/marks and recognition criteria).
Definitions and terms
- Clear terminology for claims, validation, verification, programme owner, validation/verification body, and statements-aligned with ISO/IEC 17029 and ISO/IEC 17000.
Applications
ISO/IEC TS 17035:2024 is practical for:
- Validation/verification bodies establishing or improving programme-aligned services.
- Programme owners (government agencies, trade associations, industry groups) developing sector schemes or rules.
- Accreditors and regulators assessing the adequacy of programme design and operation.
- Organisations seeking assurance over claims (environmental data, projected outcomes, product/system assertions) who want clarity on how independent validation or verification should be structured.
Use cases include verifying historical emissions data, validating projected performance claims, or creating a recognised scheme for recurring conformity assessments.

Introduction
This document is aligned with ISO/IEC 17029 which provides principles and requirements for bodies
providing validation/verification services. ISO/IEC 17029 is a generic standard that can apply to validation/
verification bodies in any economic sector or industry. It is distinct from other standards for conformity
assessment bodies in that it requires the object of conformity to be a claim, and for this to be validated
and/or verified in accordance with a validation or verification programme. Validation/verification bodies
operating in accordance with ISO/IEC 17029 can provide services as first-, second- or third-party activities.
This document is also aligned with sector-specific applications of ISO/IEC 17029, such as ISO 14065 which
references the requirements of ISO/IEC 17029 and includes specific requirements related to bodies that
validate or verify environmental information.
To validate or verify a claim, validation/verification bodies must often review large amounts of data and
information, including aspects such as the suitability of the boundaries of the claim; the way data has been
defined, collected and recorded; how quantification and calculation methods that support the claim have
been undertaken; and provision of a professional judgement on matters that are material or significant to
the claim.
The issuance of a validation or verification statement will normally be a one-off attestation based on the
information available at that point in time. Validation/verification statements normally do not have a period
of validity associated with them. Each subsequent validation/verification is a new separate conformity
assessment and is not considered to be a surveillance activity that supports an original or previous
validation/verification statement.
The result of validation or verification activities will frequently be a validation or verification statement.
These statements normally provide an opinion from the validation or verification body on the plausibility
of a claim that is made about the future based on projected data (validation), or the truthfulness of the
claim based on historical data (verification). The results from a validation and verification programme can
sometimes be combined to support a claim (e.g. a mixed engagement or in the management of similar or
related programmes). Validation/verification bodies can also be asked to undertake a validation/verification
process and issue a report of their findings, but without any formal statement or opinion on the plausibility
or truthfulness of the claim being made.
NOTE This is often referred to undertaking validation or verification activities on the basis of Agreed Upon
Procedures (AUP).
Within ISO/IEC 17029, there is a requirement for validation/verification bodies to operate within the
context of at least one validation or verification programme. Within ISO/IEC 17029 requirements, there
are many references to validation/verification programmes, and it is expected that validation/verification
programmes give direction to the validation/verification body. The importance of appropriate validation/
verification programmes when undertaking validation/verification activities in accordance with
ISO/IEC 17029 is critical to the correct operation of this type of conformity assessment.
ISO/IEC 17029:2019, Annex A also provides a comprehensive informative list of elements to be considered in
the development and operation of validation/verification programmes. The content of ISO/IEC 17029:2019,
Annex A has been included and amplified in this document.
To assist in the development, operation and recognition of validation/verification programmes suitable for
use with ISO/IEC 17029, this document covers the following:
a) an overview of validation/verification programmes in the context of ISO/IEC 17029;
b) development of validation/verification programmes;
c) recognition of validation/verification programmes.

4 Validation/Verification programmes
4.1 General
4.1.1 In accordance with ISO/IEC 17029, validation/verification are always undertaken within the context
of a validation/verification programme, in which case the operated validation/verification programme
cannot exclude any of the requirements specified by ISO/IEC 17029. This document can be used by
programmes that use another document for validation/verification bodies, in which case the programme
should not exclude or contradict the requirements in that document.
4.1.2 Programmes can be legal frameworks, a set of international, regional or national standards,
global initiatives and sector applications, as well as individual agreements with clients of the validation/
verification body.
4.1.3 Conformity assessment schemes in general comprise the full set of rules and procedures:
— describing the object of conformity assessment (claim),
— identifying the specified requirements applicable to the claim, and
— providing the methodology for performing conformity assessment (validation/verification).
NOTE The specified requirements to be identified apply to the object (i.e. relate to describing the claim). The
methodology relates to the way conformity assessment is performed (i.e. how, when, by whom), e.g. providing specific
methods and procedures for certain activities or rules for validation/verification bodies.
4.1.4 ISO/IEC 17029:2019, 3.11 defines the scope of validation/verification as the identification of the claim
as being the object of conformity assessment and the identification of the applicable specified requirements.
4.1.5 ISO/IEC 17029:2019, Clause 8 lists the following elements as content of programmes:
a) scope of validation/verification;
b) specific competence criteria for the validation/verification team and body;
c) process for validation/verification;
d) evidence gathering activities of validation/verification ;
e) reporting of validation/verification.
NOTE ISO/IEC 17029:2019, Annex A also provides additional elements.
4.1.6 The content of the programme (see 4.2) is specified by the programme owner (see 4.3).
4.1.7 Where validation/verification is performed as conformity assessment, i.e. including a decision on
whether or not to confirm the claim, the result or deliverable of the outcome of this process is a validation/
verification statement (see ISO/IEC 17029:2019, 9.7).
Where validation/verification is performed as an activity contributing to the selection, determination, and
review functions of the validation/verification process (see ISO/IEC 17029:2019, Annex B), other deliverables
than a validation/verification statement result from this activity.
© ISO/IEC 2024 – All rights reserved
In principle, a validation/verification programme can specify deliverables resulting from activities
contributing to each of the functions. For example,
— a “validation/verification plan” as a result of selection activities (see ISO/IEC 17029:2019, 9.2 and 9.4);
— an “evidence report” as a result of the selection and determination activities (see ISO/IEC 17029:2019,
9.2, 9.4 and 9.5);
— a “findings report” as a result of the review of the gathered evidence (see ISO/IEC 17029:2019, 9.6);
— a “report of actual findings”, i.e. the outcome of agreed upon procedures (AUP).
4.1.8 The deliverables associated with validation/verification programmes can be used as inputs to other
conformity assessment activities.
EXAMPLE A validation/verification statement can be used as an input into an evaluation activity of a product
certification body that fulfils ISO/IEC 17065.
Similarly, validation/verification programmes can specify that the results of other conformity assessment
activities (such as auditing, inspection, testing or certification) can be used as inputs into the validation/
verification process.
4.2 Programme content
4.2.1 Scope of validation/verification
4.2.1.1 The programme describes the claim to be the object of validation/verification, e.g. specifying
types of claims and boundaries.
4.2.1.2 The programme contains or references specified requirements to be fulfilled by the claim in order
to be confirmed.
4.2.1.3 The programme can allow for specific levels of assurance provided with the outcome of validation/
verification, e.g. reasonable, limited (see ISO/IEC 17029:2019, 9.2.2).
4.2.2 Competence, impartiality and operation of validation/verification bodies
4.2.2.1 The programme should describe means of monitoring to identify and to mitigate threats to
impartiality, e.g. consulting with the committee of the interested parties (see ISO/IEC 17029:2019, 5.3.3).
4.2.2.2 The programme can allow and set rules for providing both validation and verification to the same
client or in the context of the same project (see ISO/IEC 17029:2019, 5.3.8).
4.2.2.3 The programme can require or recommend specific arrangements to cover liability (see
ISO/IEC 17029:2019, 5.4).
4.2.2.4 The programme can specify requirements for resources, i.e. personnel, facilities, equipment,
systems and support services (see ISO/IEC 17029:2019, 7.1).
4.2.2.5 The programme can specify a period for personnel who have provided consultancy before
performing validation/verification activities (see ISO/IEC 17029:2019, 7.2.5).
4.2.2.6 The programme can require or recommend specific confidentiality requirements (see
ISO/IEC 17029:2019, 7.2.6).
© ISO/IEC 2024 – All rights reserved
4.2.2.7 The programme can specify the training requirements of personnel, including requirements for
their monitoring (see ISO/IEC 17029:2019, 7.3.2).
4.2.2.8 The programme can set rules for outsourcing, including prohibitions on outsourcing (see
ISO/IEC 17029:2019, 7.4).
4.2.2.9 The programme can specify requirements for persons carrying out the review, e.g. not being
involved in planning (see ISO/IEC 17029:2019, 9.6.2).
4.2.2.10 The programme can specify the requirements for persons making the decision on whether or not
to confirm the claim and issuing the validation/verification statement, e.g. not being involved in planning
(see ISO/IEC 17029:2019, 9.7.1.2).
4.2.3 Steps for the validation/verification process
4.2.3.1 The programme contains rules and procedures for carrying out validation/verification, e.g.
specific requirements for the pre-engagement (see 4.2.3.2), engagement (see 4.2.3.3), planning, execution
(see 4.2.4), review and decision (see 4.2.3.5 and 4.2.4.2).
4.2.3.2 Pre-engagement activities specified by the programme can include information to be submitted by
the client for pre-engagement review, time frames and any applicable fees (see ISO/IEC 17029:2019, 9.2).
4.2.3.3 Specification of the engagement agreement between the client and the validation/verification body
by the programme can include identification of the programme requirements to be covered by agreement
[see ISO/IEC 17029:2019, 9.3.1 and 9.3.3 bullet b)].
4.2.3.4 Planning and preparation activities specified by the programme can include specific terms, e.g.

Introduction
This document is aligned with ISO/IEC 17029 which provides principles and requirements for bodies
providing validation/verification services. ISO/IEC 17029 is a generic standard that can apply to validation/
verification bodies in any economic sector or industry. It is distinct from other standards for conformity
assessment bodies in that it requires the object of conformity to be a claim, and for this to be validated
and/or verified in accordance with a validation or verification programme. Validation/verification bodies
operating in accordance with ISO/IEC 17029 can provide services as first-, second- or third-party activities.
This document is also aligned with sector-specific applications of ISO/IEC 17029, such as ISO 14065 which
references the requirements of ISO/IEC 17029 and includes specific requirements related to bodies that
validate or verify environmental information.
To validate or verify a claim, validation/verification bodies must often review large amounts of data and
information, including aspects such as the suitability of the boundaries of the claim; the way data has been
defined, collected and recorded; how quantification and calculation methods that support the claim have
been undertaken; and provision of a professional judgement on matters that are material or significant to
the claim.
The issuance of a validation or verification statement will normally be a one-off attestation based on the
information available at that point in time. Validation/verification statements normally do not have a period
of validity associated with them. Each subsequent validation/verification is a new separate conformity
assessment and is not considered to be a surveillance activity that supports an original or previous
validation/verification statement.
The result of validation or verification activities will frequently be a validation or verification statement.
These statements normally provide an opinion from the validation or verification body on the plausibility
of a claim that is made about the future based on projected data (validation), or the truthfulness of the
claim based on historical data (verification). The results from a validation and verification programme can
sometimes be combined to support a claim (e.g. a mixed engagement or in the management of similar or
related programmes). Validation/verification bodies can also be asked to undertake a validation/verification
process and issue a report of their findings, but without any formal statement or opinion on the plausibility
or truthfulness of the claim being made.
NOTE This is often referred to undertaking validation or verification activities on the basis of Agreed Upon
Procedures (AUP).
Within ISO/IEC 17029, there is a requirement for validation/verification bodies to operate within the
context of at least one validation or verification programme. Within ISO/IEC 17029 requirements, there
are many references to validation/verification programmes, and it is expected that validation/verification
programmes give direction to the validation/verification body. The importance of appropriate validation/
verification programmes when undertaking validation/verification activities in accordance with
ISO/IEC 17029 is critical to the correct operation of this type of conformity assessment.
ISO/IEC 17029:2019, Annex A also provides a comprehensive informative list of elements to be considered in
the development and operation of validation/verification programmes. The content of ISO/IEC 17029:2019,
Annex A has been included and amplified in this document.
To assist in the development, operation and recognition of validation/verification programmes suitable for
use with ISO/IEC 17029, this document covers the following:
a) an overview of validation/verification programmes in the context of ISO/IEC 17029;
b) development of validation/verification programmes;
c) recognition of validation/verification programmes.

4 Validation/Verification programmes
4.1 General
4.1.1 In accordance with ISO/IEC 17029, validation/verification are always undertaken within the context
of a validation/verification programme, in which case the operated validation/verification programme
cannot exclude any of the requirements specified by ISO/IEC 17029. This document can be used by
programmes that use another document for validation/verification bodies, in which case the programme
should not exclude or contradict the requirements in that document.
4.1.2 Programmes can be legal frameworks, a set of international, regional or national standards,
global initiatives and sector applications, as well as individual agreements with clients of the validation/
verification body.
4.1.3 Conformity assessment schemes in general comprise the full set of rules and procedures:
— describing the object of conformity assessment (claim),
— identifying the specified requirements applicable to the claim, and
— providing the methodology for performing conformity assessment (validation/verification).
NOTE The specified requirements to be identified apply to the object (i.e. relate to describing the claim). The
methodology relates to the way conformity assessment is performed (i.e. how, when, by whom), e.g. providing specific
methods and procedures for certain activities or rules for validation/verification bodies.
4.1.4 ISO/IEC 17029:2019, 3.11 defines the scope of validation/verification as the identification of the claim
as being the object of conformity assessment and the identification of the applicable specified requirements.
4.1.5 ISO/IEC 17029:2019, Clause 8 lists the following elements as content of programmes:
a) scope of validation/verification;
b) specific competence criteria for the validation/verification team and body;
c) process for validation/verification;
d) evidence gathering activities of validation/verification ;
e) reporting of validation/verification.
NOTE ISO/IEC 17029:2019, Annex A also provides additional elements.
4.1.6 The content of the programme (see 4.2) is specified by the programme owner (see 4.3).
4.1.7 Where validation/verification is performed as conformity assessment, i.e. including a decision on
whether or not to confirm the claim, the result or deliverable of the outcome of this process is a validation/
verification statement (see ISO/IEC 17029:2019, 9.7).
Where validation/verification is performed as an activity contributing to the selection, determination, and
review functions of the validation/verification process (see ISO/IEC 17029:2019, Annex B), other deliverables
than a validation/verification statement result from this activity.
© ISO/IEC 2024 – All rights reserved
In principle, a validation/verification programme can specify deliverables resulting from activities
contributing to each of the functions. For example,
— a “validation/verification plan” as a result of selection activities (see ISO/IEC 17029:2019, 9.2 and 9.4);
— an “evidence report” as a result of the selection and determination activities (see ISO/IEC 17029:2019,
9.2, 9.4 and 9.5);
— a “findings report” as a result of the review of the gathered evidence (see ISO/IEC 17029:2019, 9.6);
— a “report of actual findings”, i.e. the outcome of agreed upon procedures (AUP).
4.1.8 The deliverables associated with validation/verification programmes can be used as inputs to other
conformity assessment activities.
EXAMPLE A validation/verification statement can be used as an input into an evaluation activity of a product
certification body that fulfils ISO/IEC 17065.
Similarly, validation/verification programmes can specify that the results of other conformity assessment
activities (such as auditing, inspection, testing or certification) can be used as inputs into the validation/
verification process.
4.2 Programme content
4.2.1 Scope of validation/verification
4.2.1.1 The programme describes the claim to be the object of validation/verification, e.g. specifying
types of claims and boundaries.
4.2.1.2 The programme contains or references specified requirements to be fulfilled by the claim in order
to be confirmed.
4.2.1.3 The programme can allow for specific levels of assurance provided with the outcome of validation/
verification, e.g. reasonable, limited (see ISO/IEC 17029:2019, 9.2.2).
4.2.2 Competence, impartiality and operation of validation/verification bodies
4.2.2.1 The programme should describe means of monitoring to identify and to mitigate threats to
impartiality, e.g. consulting with the committee of the interested parties (see ISO/IEC 17029:2019, 5.3.3).
4.2.2.2 The programme can allow and set rules for providing both validation and verification to the same
client or in the context of the same project (see ISO/IEC 17029:2019, 5.3.8).
4.2.2.3 The programme can require or recommend specific arrangements to cover liability (see
ISO/IEC 17029:2019, 5.4).
4.2.2.4 The programme can specify requirements for resources, i.e. personnel, facilities, equipment,
systems and support services (see ISO/IEC 17029:2019, 7.1).
4.2.2.5 The programme can specify a period for personnel who have provided consultancy before
performing validation/verification activities (see ISO/IEC 17029:2019, 7.2.5).
4.2.2.6 The programme can require or recommend specific confidentiality requirements (see
ISO/IEC 17029:2019, 7.2.6).
© ISO/IEC 2024 – All rights reserved
4.2.2.7 The programme can specify the training requirements of personnel, including requirements for
their monitoring (see ISO/IEC 17029:2019, 7.3.2).
4.2.2.8 The programme can set rules for outsourcing, including prohibitions on outsourcing (see
ISO/IEC 17029:2019, 7.4).
4.2.2.9 The programme can specify requirements for persons carrying out the review, e.g. not being
involved in planning (see ISO/IEC 17029:2019, 9.6.2).
4.2.2.10 The programme can specify the requirements for persons making the decision on whether or not
to confirm the claim and issuing the validation/verification statement, e.g. not being involved in planning
(see ISO/IEC 17029:2019, 9.7.1.2).
4.2.3 Steps for the validation/verification process
4.2.3.1 The programme contains rules and procedures for carrying out validation/verification, e.g.
specific requirements for the pre-engagement (see 4.2.3.2), engagement (see 4.2.3.3), planning, execution
(see 4.2.4), review and decision (see 4.2.3.5 and 4.2.4.2).
4.2.3.2 Pre-engagement activities specified by the programme can include information to be submitted by
the client for pre-engagement review, time frames and any applicable fees (see ISO/IEC 17029:2019, 9.2).
4.2.3.3 Specification of the engagement agreement between the client and the validation/verification body
by the programme can include identification of the programme requirements to be covered by agreement
[see ISO/IEC 17029:2019, 9.3.1 and 9.3.3 bullet b)].
4.2.3.4 Planning and preparation activities specified by the programme can include specific terms, e.g.
evidence-gathering plan, sampling plan, validation/verification plan, and criteria, e.g. for materiality,
assurance levels (see ISO/IEC 17029:2019, 9.4.1).
4.2.3.5 The programme can specify the applicable materiality and criteria for significance of evidence (see
ISO/IEC 17029:2019, 3.1.6 and 9.2.2).
4.2.3.6 The programme should provide objectives for a risk-based approach to validation/verification
activities including, among others, threats to impartiality (see ISO/IEC 17029:2019, 4.3.7).
4.2.3.7 The programme should set rule

Introducción
Este documento se alinea con la Norma ISO/IEC 17029 que proporciona principios y requisitos para
organismos que proporcionen servicios de validación/verificación. La Norma ISO/IEC 17029 es una norma
genérica que puede aplicar a organismos de validación/verificación en cualquier sector económico o
industria. Se distingue de otras normas para organismos de evaluación de la conformidad en que requiere
que el objeto de la conformidad sea una declaración, y que ésta sea validada y/o verificada de acuerdo con
un programa de validación o verificación. Los organismos de validación/verificación que operan de acuerdo
con la Norma ISO/IEC 17029 pueden proporcionar servicios como actividades de primera, segunda o tercera
parte.
Este documento también se alinea con aplicaciones específicas sectoriales de la Norma ISO/IEC 17029,
tal como la Norma ISO 14065, que hace referencia a los requisitos de la Norma ISO/IEC 17029 e incluye
requisitos específicos relacionados con organismos que validan o verifican información ambiental.
Para validar o verificar, los organismos de validación/verificación a menudo tienen que revisar grandes
cantidades de datos e información, incluyendo aspectos tales como la idoneidad de los límites de la
declaración; el modo en que los datos se han definido, recopilado y registrado; cómo se han llevado a cabo los
métodos de cuantificación y cálculo que dan soporte a la declaración; y la provisión de un juicio profesional
en asuntos que son materiales o significativos para la declaración.
La emisión de una declaración de validación o verificación normalmente será una atestación única basada
en la información disponible en ese momento. Las declaraciones de validación/verificación normalmente no
tienen un periodo de validez asociado a ellas. Cada validación/verificación posterior es una evaluación de la
conformidad aparte y no se considera que sea una actividad de vigilancia que dé soporte a una declaración
de validación/verificación original o previa.
El resultado de las actividades de validación o verificación frecuentemente será una declaración de validación
o verificación. Estas declaraciones normalmente proporcionan una opinión del organismo de validación o
verificación sobre la plausibilidad de una declaración que se hace sobre el futuro basado en datos proyectados
(validación), o sobre la veracidad de la declaración basada en datos históricos (verificación). Los resultados
de un programa de validación y de verificación a veces pueden combinarse para apoyar una declaración
(por ejemplo, un acuerdo mixto o en la gestión de programas similares o relacionados). También se puede
pedir a los organismos de validación/verificación que lleven a cabo un proceso de validación/verificación y
emitan un informe de sus hallazgos, pero sin ninguna declaración u opinión formal sobre la plausibilidad o la
veracidad de la declaración que se está haciendo.
NOTA Esto, a menudo, se denomina llevar a cabo actividades de validación o verificación basándose en
procedimientos de común acuerdo (PCA).
Dentro de la Norma ISO/IEC 17029, hay un requisito para que los organismos de validación/verificación
operen dentro del contexto de al menos un programa de validación o verificación. Dentro de los requisitos
de la Norma ISO/IEC 17029, hay muchas referencias a programas de validación/verificación, y se espera que
esos programas de validación/verificación orienten al organismo de validación/ verificación. La importancia
de los programas de validación/verificación adecuados cuando se llevan a cabo actividades de validación/
verificación de acuerdo con la Norma ISO/IEC 17029 es crítica para el funcionamiento correcto de este tipo
de evaluación de la conformidad.
El Anexo A de la Norma ISO/IEC 17029:2019 también proporciona una amplia lista informativa de elementos
a considerar en el desarrollo y el funcionamiento de los programas de validación/verificación. El contenido
del Anexo A de la Norma ISO/IEC 17029:2019 se ha incluido y ampliado en este documento.
Para ayudar en el desarrollo, el funcionamiento y el reconocimiento de programas de validación/ verificación
idóneos para su uso con la Norma ISO/IEC 17029, este documento cubre lo siguiente:
a) un resumen de los programas de validación/verificación en el contexto de la Norma ISO/IEC 17029;
b) desarrollo de programas de validación/verificación;
c) reconocimiento de programas de validación/verificación.

4 Programas de validación/verificación
4.1 Generalidades
4.1.1 De acuerdo con la Norma ISO/IEC 17029, la validación/la verificación siempre se lleva a cabo dentro
del contexto de un programa de validación/verificación, en cuyo caso el programa de validación/verificación
operado no puede excluir ninguno de los requisitos especificados por la Norma ISO/IEC 17029. Este
documento puede ser utilizado por programas que usen otro documento para organismos de validación/
verificación, en cuyo caso el programa no debería excluir o contradecir los requisitos de ese documento.
4.1.2 Los programas pueden ser marcos de referencia legales, un conjunto de normas internacionales,
regionales o nacionales, iniciativas globales y aplicaciones sectoriales, así como acuerdos individuales con
los clientes del organismo de validación/verificación.
4.1.3 En general, los esquemas de evaluación de la conformidad comprenden el conjunto completo de
reglas y procedimientos que:
— describen el objeto de la evaluación de la conformidad (declaración),
— identifican los requisitos especificados aplicables a la declaración, y
— proporcionan la metodología para llevar a cabo la evaluación de la conformidad (validación/ verificación).
NOTA Los requisitos especificados que se han de identificar se aplican al objeto (es decir, se relacionan con la
descripción de la declaración). La metodología está relacionada con la manera en que se lleva a cabo la evaluación de la
conformidad (es decir, cómo, cuándo y por quién), por ejemplo, proporcionando métodos y procedimientos específicos
para ciertas actividades o reglas para los organismos de validación/verificación.
4.1.4 El apartado 3.11 de la Norma ISO/IEC 17029:2019 define el alcance de la validación/verificación como
la identificación de la declaración que va a ser el objeto de la evaluación de la conformidad y la identificación
de los requisitos especificados aplicables.

4.1.5 El Capítulo 8 de la Norma ISO/IEC 17029:2019 enumera los siguientes elementos como contenido de
los programas:
a) el alcance de la validación/verificación;
b) los criterios de competencia específica para el organismo y el equipo de validación/verificación;
c) un proceso de validación/verificación;
d) las actividades de recopilación de evidencias de validación/verificación;
e) la presentación de informes de validación/verificación.
NOTA El Anexo A de la Norma ISO/IEC 17029:2019 también proporciona elementos adicionales.
4.1.6 El dueño del programa (véase 4.3) especifica el contenido del programa (véase 4.2).
4.1.7 Cuando una validación/verificación se lleva a cabo como una evaluación de la conformidad, es decir,
incluyendo una decisión sobre si confirmar o no la declaración, el resultado o el entregable del resultado de
este proceso es una declaración de validación/verificación (véase ISO/IEC 17029:2019, 9.7).
Cuando una validación/verificación se lleva a cabo como una actividad que contribuye a la selección, la
determinación y la revisión de funciones del proceso de validación/verificación (véase el Anexo B de la
Norma ISO/IEC 17029:2019), de esta actividad resultan otros entregables distintos de una declaración de
validación/verificación.
En principio, un programa de validación/verificación puede especificar los entregables que resultan de las
actividades que contribuyen a cada una de las funciones. Por ejemplo,
— un “plan de validación/verificación” como resultado de las actividades de selección (véanse
ISO/IEC 17029:2019, 9.2 y 9.4);
— un “informe de evidencias” como resultado de las actividades de selección y determinación (véanse
ISO/IEC 17029:2019, 9.2, 9.4 y 9.5);
— un “informe de hallazgos” como resultado de la revisión de la evidencia recopilada (véase
ISO/IEC 17029:2019, 9.6);
— un “informe de los hallazgos reales”, es decir, el resultado de los procedimientos de común acuerdo (PCA).
4.1.8 Los entregables asociados a los programas de validación/verificación pueden utilizarse como
entradas para otras actividades de evaluación de la conformidad.
EJEMPLO Una declaración de validación/verificación puede utilizarse como una entrada para una actividad de
evaluación de un organismo de certificación de productos que cumpla la Norma ISO/IEC 17065.
De forma similar, los programas de validación/verificación pueden especificar que los resultados de
otras actividades de evaluación de la conformidad (tales como la auditoría, la inspección, los ensayos o la
certificación) pueden utilizarse como entradas para el proceso de validación/verificación.
4.2 Contenido del programa
4.2.1 Alcance de la validación/verificación
4.2.1.1 El programa describe la declaración que va a ser el objeto de la validación/verificación, por ejemplo,
especificando los tipos de declaraciones y sus límites.
4.2.1.2 El programa contiene requisitos especificados que la declaración tiene que cumplir para ser
confirmada, o hace referencia a ellos.

resultado de la validación/verificación, por ejemplo, razonable, limitado (véase ISO/IEC 17029:2019, 9.2.2).
4.2.2 Competencia, imparcialidad y operación de los organismos de validación/verificación
4.2.2.1 El programa debería describir los medios para realizar el seguimiento para identificar y mitigar
las amenazas a la imparcialidad, por ejemplo, consultar con el comité de las partes interesadas (véase
ISO/IEC 17029:2019, 5.3.3).
4.2.2.2 El programa puede contemplar y establecer reglas para proporcionar tanto validación como
verificación al mismo cliente o en el contexto del mismo proyecto (véase ISO/IEC 17029:2019, 5.3.8).
4.2.2.3 El programa puede requerir o recomendar disposiciones específicas para cubrir la responsabilidad
legal (véase ISO/IEC 17029:2019, 5.4).
4.2.2.4 El programa puede especificar requisitos para los recursos, es decir, el personal, las instalaciones,
el equipamiento, los sistemas y los servicios de soporte (véase ISO/IEC 17029:2019, 7.1).
4.2.2.5 El programa puede especificar un periodo para el personal que ha proporcionado consultoría
antes de llevar a cabo actividades de validación/verificación (véase ISO/IEC 17029:2019, 7.2.5).
4.2.2.6 El programa puede requerir o recomendar requisitos de confidencialidad específicos (véase
ISO/IEC 17029:2019, 7.2.6).
4.2.2.7 El programa puede especificar los requisitos de formación del personal, incluyendo requisitos para
su seguimiento (véase ISO/IEC 17029:2019, 7.3.2).
4.2.2.8 El programa puede establecer reglas para la contratación externa, incluyendo prohibiciones
aplicables a la contratación externa (véase ISO/IEC 17029:2019, 7.4).
4.2.2.9 El programa puede especificar requisitos para las personas que llevan a cabo la revisión, por
ejemplo, que no estén involucradas en la planificación (véase ISO/IEC 17029:2019, 9.6.2).
4.2.2.10 El programa puede especificar los requisitos para las personas que toman la decisión de si
confirmar o no la declaración y emitir la declaración de la validación/verificación, por ejemplo, que no estén
involucradas en la planificación (véase ISO/IEC 17029:2019, 9.7.1.2).
4.2.3 Pasos para el proceso de validación/verificación
4.2.3.1 El programa contiene reglas y procedimientos para llevar a cabo la validación/verificación, por
ejemplo, requisitos específicos para el preacuerdo (véase 4.2.3.2), el acuerdo (véase 4.2.3.3), la planificación,
la ejecución (véase 4.2.4), la revisión y la decisión (véanse 4.2.3.5 y 4.2.4.2).
4.2.3.2 Las actividades de preacuerdo especificadas por el programa pueden incluir información a
presentar por el cliente para la revisión del preacuerdo, marcos temporales y cualquier tarifa aplicable
(véase ISO/IEC 17029:2019, 9.2).
4.2.3.3 La especificación del acuerdo de compromiso entre el cliente y el organismo de validación/
verificación en el programa puede incluir la identificación de los requisitos del programa que tiene que
cubrir el acuerdo [véase ISO/IEC 17029:2019, 9.3.1 y 9.3.3 punto b)].
4.2.3.4 Las actividades de planificación y preparación especificadas en el programa pueden incluir
términos específicos, por ejemplo, plan de recopilación de evidencias, plan de muestreo, plan de
