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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 12576 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 12576-1 was prepared by Technical Committee ISO/TC 163, Thermal insulation,
Subcommittee SC 3, Insulation products for building applications.
ISO 12576 consists of the following parts, under the general title Thermal insulation — Insulating materials and
products for buildings — Conformity control systems
— Part 1: Factory-made products
Part 2 (Site-made products) is in course of preparation.

INTERNATIONAL STANDARD ISO 12576-1:2001(E)
Thermal insulation — Insulating materials and products for
buildings — Conformity control systems
Part 1:
Factory-made products
1 Scope
This part of ISO 12576 establishes five systems for the conformity control of thermal insulating materials and
products for buildings that are factory made.
Its purpose is to provide uniform methods that are used to determine whether a production or a consignment of a
thermal insulating material should be accepted as conforming to the relevant specification requirements.
This part of ISO 12576 provides minimum requirements for each of the systems.
Other systems may be additionally applied when agreed upon between the supplier and purchaser.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 12576. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 12576 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated below. For undated references,
the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of
currently valid International Standards.

3 Terms and definitions
For the purposes of this part of ISO 12576, the terms and definitions given in ISO 9229 and the following apply.
3.1
acceptance testing
tests to be carried out to prove whether a product may be accepted as conforming to specified requirements
©
ISO 2001 – All rights reserved 1

3.2
Acceptance Quality Limit
AQL
designated value of percent nonconforming (or nonconformities per 100 units) that will be accepted most of the time
by thesampling schemetobe used
NOTE See ISO 2859-1:1999.
3.3
assessment of factory production control
action by an approved body demonstrating that the factory production control is in conformity with the requirements,
based on initial inspection of the factory and the factory production control and continuous surveillance of it
3.4
audit test
one or more tests usually performed by, or on behalf of a certification body, to confirm that a product continues to
conform to the requirements of a specification and to provide information to assess the effectiveness of the factory
production control
3.5
certification body
body that conducts certification
NOTE A certification body may operate its own testing and inspection activities or oversee these activities carried out on its
behalf by other bodies.
[ISO/IEC Guide 2:1996, definition 15.2]
3.6
certification of conformity
action by an approved certification body demonstrating that adequate confidence is provided that a product is in
conformity with the relevant product specification
3.7
conformity control
performance of control methods to prove whether a product may be accepted as conforming to specified
requirements
3.8
consignment
quantity of packages or boards of the same category delivered at one time
NOTE The consignment may consist of one or more inspection lots or parts of an inspection lot.
3.9
factory production control
permanent internal control of production exercised by the manufacturer or his agent
NOTE Factory production control comprises operational techniques and all measures necessary to maintain and to regulate the
quality of the product up to delivery. It consists of inspections and tests and the utilization of their results with regard to equipment,
basic materials and constituents, manufacturing processes and the products themselves, and of taking into account the
corresponding requirements given by the product specification.
3.10
initial type test
one or more tests performed on a product prior to commencing normal production to prove that the product is
capable of conforming to the relevant requirements of a specification

3.11
inspection lot
definite quantity of packages (product items) manufactured under conditions which are presumed uniform, and that
are submitted for inspection and accepted or rejected as a whole, depending on the quality found by inspection of the
representative samples drawn from the lot
3.12
item
defined quantity of material, on which a set of observations may be made
EXAMPLE A full-size product, board, roll or package.
3.13
lot testing
system under which a lot, represented by a specified number of items of the product, is tested and the result used to
judge the measure of conformity with the specification
NOTE The judgement is on the lot and not on the ongoing production as a whole.
3.14
manufacturer's declaration of conformity
action by which a manufacturer declares under his own responsibility that the product is in conformity with the
specification, without being under procedures of a third-party certification system
3.15

test performed by the manufacturer, at specified intervals, to confirm that the product conforms to the relevant
requirements of the specification
3.16

definite quantity of some commodity manufactured or produced under conditions which are presumed uniform
3.17
production line
production unit
set of equipment which produces a product

3.19
sample size
number of items in the sample
[ISO 2859-1:1999]
3.20
sampling unit
for the purpose of sampling, an item taken from the production batch
