Foreword
This European Standard has been prepared by Technical Committee CEN/TC 88 "Thermal insulating
materials and products", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by November 2001, and conflicting national standards shall be
withdrawn at the latest by March 2003.
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).
It supports a series of product standards for thermal insulating materials and products, which are necessary
for the demonstration of compliance with the mandate derived from the Construction Products Directive
89/106/EEC.
This European Standard contains five informative annexes:
Annex A  Certification of conformity (not for CE marking purposes)
Annex B  Certification of conformity (for products of reaction to fire classes under system 1)
Annex C  Declaration of conformity by the manufacturer (for the performance requirements under
system 3)
Annex D  Declaration of conformity by the manufacturer (for products of reaction to fire classes
under system 4)
Annex E  Guidance on the use of annex(es)
Evaluation of conformity is necessary for products in order to provide support for CE marking and for
voluntary certification. The guidance contained in annex ZA of the product standards will determine which
of the above annexes shall be used for CE marking.
Annex E describes how to use the anexes together with the mainbody of this standard to fullfill the
requirements to the certification and/or declaration of conformity for a product.
Although the annexes are informative in this standard, their use by the manufacturer will require that they
assume a normative status. When an annex is used the requirements in the annex shall be followed, as
given in the text.
This standard applies to factory made products for buildings, factory made products for building equipment
and industrial installations, in-situ products for buildings, in-situ products for building equipment and
industrial installations and to external thermal insulation composite systems.
No existing European Standard is superseded.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal,
Spain, Sweden, Switzerland and the United Kingdom.

Page 5
EN 13172:2001
Providing that a product within the group meets the requirements of the product standard then all products
within the same group shall be deemed to comply with the product standard. If the same product fails to
comply with the product standard then the whole group shall be assumed to have failed to comply with the
product standard.
Products, which differ only with regard to some properties, may be grouped together by their common
properties. Providing that a product within a defined group meets the requirements of the product standard,
then all products within this group shall be deemed to comply with the product standard for the properties
concerned. The properties outside this(these) common group(s) shall be tested product by product.
5  Requirements for factory production control - Tasks for the
manufacturer

For thermal properties a part of the calibration shall be to compare test results obtained by the
manufacturer with those obtained by an approved body on the same sample.
When production is intermittent the manufacturer shall ensure that test equipment which may be affected
by the interruption is suitably checked and/or calibrated before use.
The calibration of all test equipment shall be repeated if any repair or failure which could upset the
calibration of the test equipment occurs.
5.3.3  Inspection and testing of raw materials and other constituent materials
The manufacturer shall ensure that raw materials and other constituent materials conform to his specified
requirements. In determining the checks necessary consideration shall be given to the control exercised by
the supplier and the documented evidence of conformity.
The manufacturer shall ensure that incoming raw materials and other constituent materials are used or
processed only after they have been verified as conforming to the specified requirements. Where incoming
material is released for urgent production purposes prior to verification it shall be identified and recorded in
order to permit immediate recall in the event of nonconformity.
5.3.4  Inspection and testing during manufacture
In order to manufacture products which conform to the product standard the manufacturer shall control his
process and perform inspection and tests as described in his quality manual.
5.3.5  Product testing
5.3.5.1  Direct testing
Prior to placing a product on the market that is to be manufactured to a given specification, the
manufacturer shall carry out initial type testing in accordance with clause 6.
The manufacturer shall regularly test the finished products. These tests shall be carried out in accordance
with the relevant product standard, using direct and/or indirect testing, in accordance with 5.3.5.2. One test
is considered as the test(s) on one sample of the product consisting of one or more test specimens as
specified in the relevant test or product standard.
The samples shall be drawn periodically from each production unit (line) according to the manufacturer's
test plan. The minimum testing frequencies for the relevant properties for continuous production conditions
are specified in the annex ‘Factory production control’ of the relevant product standard. For properties that
are automatically recorded during the manufacturing process at a higher frequency than given in this

---------------------- Page: 9 ----------------------

SIST EN 13172:2002
Page 8
EN 13172:2001
annex, the testing frequency may be lowered.
In the special case, where for a given property, a highly controlled production process can be demonstrated
according to equation (1), the testing frequency may be reduced to once a day.
|T|  k x s (1)
where
T is the tolerance as specified in the product standard;
s is the estimate of the standard deviation of the property;
k is a factor corresponding to the number of test results available.
k

NOTE  For other numbers of test results see ISO 3207, Statistical interpretation of data – Determination of a
statistical tolerance interval
. Linear interpolation is acceptable.
Satisfaction of the requirement of equation (1) shall be verified in the event of failure and at least once a
year.
5.3.5.2  Indirect testing
Indirect testing is a means by which a given property may be assessed through tests on one or more other
properties, with which a correlation has been established. Indirect testing may also be used to reduce the
testing frequency of direct testing.
The correlation shall be established by suitable statistical means, e.g. regression analysis on the basis of
adequate preliminary tests for each production unit (line). It shall be reexamined at prescribed intervals and
after changes or modifications if these are likely to affect the correlation.
For each indirect testing procedure applied at the place of production the sampling plan and the compliance
criteria, for the indirect property, shall be specified taking into account the relevant correlation between the
corresponding properties.
The use of indirect testing shall result in at least the same confidence level on the property concerned as
when using the direct testing.
In case of dispute the test method specified for the relevant property in the product standard shall be used.
5.3.6  Inspection and test status
The conformity or nonconformity of a product with the product standard shall be determined by tests and
inspection which records passed, failed or due to be reclassified.

SIST EN 13172:2002
Page 9
EN 13172:2001
5.3.7  Inspection and test records (manufacturer's log)
The results of finished products inspection and testing shall be recorded in the manufacturer's log. The log
shall contain a record of the product identification, the date and time of manufacture, and for each property
the test methods, the test results, the required level, the inspection result and the identification of the
person carrying out the inspection.
Where products do not meet the requirements of the product standard, a note shall be made in the
manufacturer's log of the remedial measures taken.
The manufacturer's log shall be kept for at least 10 years.
5.4  Actions in the case of nonconforming products
If the result of a test or the inspection of a product is a failure, the manufacturer shall immediately take the
steps necessary to rectify the deficiency. Products, which do not conform to the requirements of the product
standard, shall be marked accordingly. When the deficiency has been identified and rectified, the test or
inspection in question shall be repeated without delay according to the quality manual, to provide evidence
that the defects have been overcome.
In the event that products are dispatched before the result of the inspection is available prompt notification
shall be given to the customer to prevent any consequential damage and a record maintained of such
notification.
Products, which have not met the value intended to be declared by the manufacturer for a given property
shall be permitted to qualify for a lower value of that property and shall be labelled accordingly.
5.5  Handling, storage, packaging, and marking of products
In accordance with the quality manual (see 5.2) the manufacturer shall:
1) provide methods of handling that prevent damage or deterioration;
2) provide suitable storage areas or stock rooms to prevent damage or
   deterioration of the product;
3) control the packaging, storage and the marking processes.
5.6  Traceability of products
Individual products or product batches shall be identifiable and traceable with regard to their production
origin.
5.7  Training of personnel
The manufacturer shall establish and maintain procedures for the identification of the training needs and
shall provide for the training of all personnel in activities affecting quality.
Personnel performing specific assigned tasks shall be qualified on the basis of appropriate education,
training and/or experience, as required.
Records of training shall be kept up to date.

EN 13172:2001
6  Initial type testing
Prior to placing a product on the market that is to be manufactured to a given specification, the
manufacturer shall carry out initial type testing in order to ensure product conformity. Initial type testing of
relevant properties shall be repeated on changes or modifications if these are likely to affect the conformity
of the products.
These tests shall be carried out in accordance with the product standard, by direct testing. One test is
considered as the test of one sample of the product consisting of one or more test specimens as specified
in the relevant test or product standard.
For CE marking purposes the initial type testing of some characteristics shall be performed by an approved
body (see the product standard).
7  Procedure in case of nonconformity and/or complaint on declared
thermal resistance or thermal conductivity
This procedure gives the requirements to be used in the case of nonconformity and/or to find out if a
complaint regarding the thermal resistance or the thermal conductivity declared by a manufacturer is
correct or not.
NOTE 1  The procedure although based on a simplified approach follows in principle the 90/90 % approach.
NOTE 2  It is not aimed at checking whether a specific lot is conforming to the value declared by the manufacturer.
1) The complaining party shall ask for a representative sample to be taken by an independent party from,
e.g. the market place. He shall ask the independent party to write a report giving the identification of
the product, where it was bought, at what date and to give the identification number of the package.
2) The sample shall be transported, without significant deterioration, to an approved testing laboratory,
chosen by the complaining party.
3) The approved testing laboratory shall make a first measurement of thermal resistance or thermal
conductivity.
4) If the result of the first measurement fails to meet the declared values by more than 15 % the product
shall be deemed to have failed.
5) If the first measurement does not deviate from the declared values the product shall be deemed to
have passed.
6) If the result of the first measurement fails to meet the declared value by 15 % or less, three other
samples shall be taken from three different production runs and handled as in 1. and 2.
7) The approved testing laboratory shall make one measurement on each sample.
8) If any one of the three test results fails to meet the declared value the product is deemed to have
failed.
9) If the product fails the manufacturer shall be informed by the approved testing laboratory.
10) If the product has failed the manufacturer shall agree to repeat the procedure described in A.2.3 or
C.2.2 as relevant, for the product or product group, by applying for a new initial type test within 4
weeks.

---------------------- Page: 12 ----------------------

SIST EN 13172:2002

Annex A
(informative)

Certification of conformity (not for CE marking purposes)
NOTE  This annex supports the standards for thermal insulation products. When used in the evaluation of
conformity of these products its use is mandatory. For this reason the text of the annex, where appropriate, is written
in the imperative form.
A.1  Bodies involved in the evaluation of conformity procedure
The following external bodies may be involved in the evaluation of conformity of products with this
standard:
1) certification body which provides conformity certification;
2) inspection body, which performs assessments, makes recommendations on the acceptability of
manufacturer's factory production control, performs subsequent audits and which selects samples of
products for testing;
3) testing laboratory, which measures, examines, tests or otherwise determines the characteristics or
performance of materials or products and which calibrates equipment.
NOTE  The functions of these three bodies may be performed by the certification body or by different bodies. If
different bodies are involved, the inspection body and/or the testing laboratory carry out their functions on behalf of
the certification body.
In this annex these bodies are referred to by the term "approved body".
A.2  Tasks for the approved body
A.2.1  General
Clause A.2 specifies the tasks for the approved body in the evaluation of conformity procedure and also
the manufacturer's duties arising in connection with them.
If a quality system certified to a quality system standard, such as EN ISO 9001, is used, this certification
shall be taken into account by the product certification body for those elements that are common to both
systems.
A.2.2  Initial inspection
The initial inspection shall determine whether the prerequisites for staff and equipment, for continuous and
orderly manufacture and for the corresponding factory production control, are in accordance with clause 5.
The results and recommendations from the initial inspection shall be documented in an assessment
report. This shall include evidence that all the requirements of clause 5 have been assessed.
A.2.3  Initial type testing
Each product, which is submitted for assessment, shall be tested by the approved body in accordance
with the product standard.
