ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

Introduction
The main objectives of standardization of testing methods are to create the means by which comparable
results can be obtained on different occasions, with different instruments and in different laboratories,
and to control the processes that determine the acceptability of a product. Most testing methods for
paper, board and pulps are linked by some type of reference standards to which the numerical results
are to be related. In many cases, the comparison is made by means of readily available instruments of
appropriate accuracy: for example, a balance with certified weights, a chronometer, a calibrated length-
measuring device such as a micrometer, etc. However, in certain instances, the relation to the reference
standard may not be obvious, or there may be practical problems in measuring particular properties;
the test method should therefore include additional instructions for ensuring reasonable accuracy of the
results. This may be accomplished with the aid of transfer standards, when the results are related either
to certain properties of a unique reference standard, or to results obtained at specified laboratories
entrusted with the performance of certain delicate measurements. Standardizing Laboratories and
Authorized Laboratories act as links in supplying the transfer standards required.
The acceptance of testing and calibration results between countries will be facilitated if specified
laboratories authorized to issue optical reference transfer standards comply with this document or if
they obtain accreditation from bodies which have entered into mutual recognition agreements with
equivalent bodies in other countries using this document.
The use of this document will facilitate cooperation between specified laboratories authorized to issue
optical reference transfer standards and other bodies, and assist in the exchange of information and
experience, and in the harmonization of calibration standards and procedures.
A laboratory’s fulfilment of the requirements of this document means the laboratory meets both the
general and specific technical competence requirements, and the management system requirements
that are necessary for it to consistently deliver technically valid results.

through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
The main objectives of standardization of testing methods are to create the means by which comparable
results can be obtained on different occasions, with different instruments and in different laboratories,
and to control the processes that determine the acceptability of a product. Most testing methods for
paper, board and pulps are linked by some type of reference standards to which the numerical results
are to be related. In many cases, the comparison is made by means of readily available instruments of
appropriate accuracy: for example, a balance with certified weights, a chronometer, a calibrated length-
measuring device such as a micrometer, etc. However, in certain instances, the relation to the reference
standard may not be obvious, or there may be practical problems in measuring particular properties;
the test method should therefore include additional instructions for ensuring reasonable accuracy of the
results. This may be accomplished with the aid of transfer standards, when the results are related either
to certain properties of a unique reference standard, or to results obtained at specified laboratories
entrusted with the performance of certain delicate measurements. Standardizing Laboratories and
Authorized Laboratories act as links in supplying the transfer standards required.
The acceptance of testing and calibration results between countries will be facilitated if specified
laboratories authorized to issue optical reference transfer standards comply with this document or if
they obtain accreditation from bodies which have entered into mutual recognition agreements with
equivalent bodies in other countries using this document.
The use of this document will facilitate cooperation between specified laboratories authorized to issue
optical reference transfer standards and other bodies, and assist in the exchange of information and
experience, and in the harmonization of calibration standards and procedures.
A laboratory’s fulfilment of the requirements of this document means the laboratory meets both the
general and specific technical competence requirements, and the management system requirements
that are necessary for it to consistently deliver technically valid results.

Paper, board and pulps — General requirements for the
competence of laboratories authorized for the issue of
optical reference transfer standards of level 3
1 Scope
This document provides both general requirements and specific requirements (Annex A) for laboratories
seeking to become “Authorized Laboratories (ALs)” and to maintain their Authorized Laboratory status
for the issue of optical reference transfer standards of level 3. This document follows the requirements
and adopts the format of ISO/IEC 17025, with the aims of:
a) establishing and maintaining international optical reference transfer standards of level 2 (IR2)
traceable to an international optical reference primary standard of level 1 (IR1) maintained by a
standardizing laboratory;
b) distributing traceability required to achieve inter-laboratory agreement in the results of test
methods specified in International Standards for optical properties of paper, board or pulp;
c) participating in the design and development of new methods and international harmonization of
procedures.
When a laboratory does not undertake one or more of the activities covered by this document, such as
sampling and the design/development of new methods, the requirements of those clauses do not apply.
This document is for use by specified laboratories authorized to issue optical reference transfer
standards in developing their management system for quality, administrative and technical operations.
Laboratory customers, regulatory authorities and accreditation bodies can also use it in confirming or
recognizing the competence of laboratories.
NOTE It might be necessary to explain or interpret certain requirements in this document to ensure that
the requirements are applied in a consistent manner. Guidance for consistent application can be obtained from
Technical Committee ISO/TC 6.

Introduction
Les principaux objectifs de la normalisation des méthodes d'essai sont de créer les moyens permettant
l'obtention de résultats comparables à des moments différents, en utilisant des instruments différents
et dans des laboratoires différents, et de contrôler les procédés qui déterminent l'acceptabilité d'un
produit. La plupart des méthodes d'essai pour le papier, le carton et les pâtes sont liées à un type d'étalons
de référence auquel les résultats numériques sont reliés. Dans de nombreux cas, la comparaison est
effectuée à l'aide d'instruments aisément disponibles et d'une exactitude appropriée: par exemple
une balance pourvue de masses certifiées, un chronomètre, un appareil étalonné destiné à mesurer
la longueur tel qu'un micromètre, etc. Cependant, dans certains cas, la relation à l'étalon de référence
est peu évidente ou il peut y avoir des problèmes pratiques lors du mesurage de certaines propriétés.
Il convient que la méthode d'essai inclue des instructions additionnelles afin d'assurer une exactitude
raisonnable des résultats. Cela peut être accompli à l'aide d'étalons de transfert, lorsque les résultats
sont liés soit à certaines propriétés d'un étalon de référence unique, soit à des résultats obtenus dans
des laboratoires expressément mandatés à veiller à la performance de certains mesurages délicats. Les
laboratoires de référence et les laboratoires agréés agissent comme maillons pour fournir les étalons de
transfert requis.
L'acceptation des résultats d'essai et d'étalonnage d'un pays à l'autre se trouvera facilitée si les
laboratoires mandatés autorisés à délivrer des étalons de référence de transfert optiques se conforment
au présent document ou s'ils obtiennent l'accréditation auprès d'organismes prenant part à des accords
de reconnaissance mutuelle avec des organismes équivalents utilisant le présent document dans
d'autres pays.
L'usage du présent document favorise la collaboration entre les laboratoires mandatés autorisés à
délivrer des étalons de référence de transfert optiques et d'autres organismes et contribue à l'échange
d'informations et d'expérience, ainsi qu'à l'harmonisation des normes et procédures d'étalonnage.
Le respect des exigences du présent document par un laboratoire signifie que ce dernier satisfait à
la fois aux exigences générales et spécifiques de compétence technique et aux exigences relatives
aux systèmes de management qui sont nécessaires pour qu'il délivre en permanence des résultats
techniquement valides.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction
The main objectives of standardization of testing methods are to create the means by which comparable
results can be obtained on different occasions, with different instruments and in different laboratories,
and to control the processes that determine the acceptability of a product. Most testing methods for
paper, board and pulps are linked by some type of reference standards to which the numerical results
are to be related. In many cases, the comparison is made by means of readily available instruments of
appropriate accuracy: for example, a balance with certified weights, a chronometer, a calibrated length-
measuring device such as a micrometer, etc. However, in certain instances, the relation to the reference
standard may not be obvious, or there may be practical problems in measuring particular properties;
the test method should therefore include additional instructions for ensuring reasonable accuracy of the
results. This may be accomplished with the aid of transfer standards, when the results are related either
to certain properties of a unique reference standard, or to results obtained at specified laboratories
entrusted with the performance of certain delicate measurements. Standardizing Laboratories and
Authorized Laboratories act as links in supplying the transfer standards required.
The acceptance of testing and calibration results between countries will be facilitated if specified
laboratories authorized to issue optical reference transfer standards comply with this document or if
they obtain accreditation from bodies which have entered into mutual recognition agreements with
equivalent bodies in other countries using this document.
The use of this document will facilitate cooperation between specified laboratories authorized to issue
optical reference transfer standards and other bodies, and assist in the exchange of information and
experience, and in the harmonization of calibration standards and procedures.
A laboratory’s fulfilment of the requirements of this document means the laboratory meets both the
general and specific technical competence requirements, and the management system requirements
that are necessary for it to consistently deliver technically valid results.

Paper, board and pulps — General requirements for the
competence of laboratories authorized for the issue of
optical reference transfer standards of level 3
1 Scope
This document provides both general requirements and specific requirements (Annex A) for laboratories
seeking to become “Authorized Laboratories (ALs)” and to maintain their Authorized Laboratory status
for the issue of optical reference transfer standards of level 3. This document follows the requirements
and adopts the format of ISO/IEC 17025, with the aims of:
a) establishing and maintaining international optical reference transfer standards of level 2 (IR2)
traceable to an international optical reference primary standard of level 1 (IR1) maintained by a
standardizing laboratory;
b) distributing traceability required to achieve inter-laboratory agreement in the results of test
methods specified in International Standards for optical properties of paper, board or pulp;
c) participating in the design and development of new methods and international harmonization of
procedures.
When a laboratory does not undertake one or more of the activities covered by this document, such as
sampling and the design/development of new methods, the requirements of those clauses do not apply.
This document is for use by specified laboratories authorized to issue optical reference transfer
standards in developing their management system for quality, administrative and technical operations.
Laboratory customers, regulatory authorities and accreditation bodies can also use it in confirming or
recognizing the competence of laboratories.
NOTE It might be necessary to explain or interpret certain requirements in this document to ensure that
the requirements are applied in a consistent manner. Guidance for consistent application can be obtained from
Technical Committee ISO/TC 6.
