For the purposes of this document, the following terms and definitions apply.
3.1
product
item or good produced under conditions which are presumed uniform to a given specification and placed on the
market
3.2
factory production control
permanent, internal control of production exercised either by the manufacturer or by his agent on the responsibility of
the manufacturer himself
NOTE Factory production control comprises operational techniques and all measures necessary to regulate and maintain the
conformity of the product to the requirements of the relevant product standard.
3.3
production line
assemblage of equipment that produces products using a continuous process
3.4

4 General requirements
The evaluation of conformity involves either a manufacturer or a manufacturer in conjunction with a third party. The
procedure is given either in the relevant product standard or agreed between parties; it shall include at least those
tasks given in Clause 5. The tasks for the third party and/or the manufacturer shall be carried out in accordance with
the requirements of Clause 7 of the product standard, which makes reference to this standard and one or more of the
Annexes B, C, or D for the purposes of CE marking.
NOTE 1 Annex A is included for the purposes of voluntary product certification.
NOTE 2 Annex F is included for the purposes of describing how to handle the case of a complaint (outside the scope of a
voluntary certification, in which case the Annex A rules apply)
The content of Clause 5 will also be met by supplementing the provisions of EN ISO 9001 with requirements of this
standard.
For ITT and FPC, each production line is considered separately.
For ITT and FPC, production units using the same process in one factory are considered together (as if one
production line).
Products may be collected into product groups for declaration and testing purposes subject to the following
conditions:
 They shall have the same type of production process and shall be derived from the same family of raw material;
a distinction is made between glass wool and rock wool and between foams with different blowing agents;
 They shall differ only in aspects that do not influence the properties required in the relevant product standard;
 They shall be covered by a single thermal insulation standard, e.g. from the series EN 13162 to EN 13171;
 Products which differ only with regard to some properties may be grouped together by their common properties;
 Products which are identical except the facing and for which the different facings have been shown to have the
same effect on the declared characteristics (e.g. regarding thermal properties, the gas tight facings of some PUR
products), may be grouped;
Products covered by more than one European Standard may be grouped for testing purposes only providing that,
 they have a common production specification and that they are from the same type of production process and
the same family of raw material, e.g. cellular glass for the EN 13167 and prEN 14305.
The properties outside this (these) common group(s) shall be tested product by product.
Products which are outside the scope of a product standard cannot be grouped for declaration purposes with
products declared under the scope of that standard.
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 for the properties concerned. 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.
5 Requirements for factory production control - Tasks for the manufacturer
5.1 General
This clause specifies the requirements for factory production control that shall be fulfilled by the manufacturer for
each factory.
5.2 Organisation
5.2.1 General
Factory production control shall be operated according to a documented system that shall be given in a quality
manual.
5.2.2 Responsibility and authority
The responsibility, authority and the interrelationships between all personnel who manage, perform, or verify work
affecting quality, shall be defined. This applies particularly to personnel who need the organisational freedom and
authority to:
a) initiate action to prevent the occurrence of product nonconformity;
b) identify and record any product quality problems.
5.2.3 Management representative for factory production control
At every place of production, a representative, with the appropriate knowledge and production experience, shall be
appointed by the manufacturer and given responsibility for managing and supervising factory production control
procedures and for ensuring that the requirements of this standard are implemented and maintained.
5.2.4 Management review
Management shall review at appropriate intervals the factory production control system to ensure its continuing
suitability and effectiveness. Records of such reviews shall be maintained.
5.3 Quality manual

5.4) and possible retest procedures (see 5.5);
e) procedures for handling, storage, packaging, marking and labelling the product;
f) procedures for all personnel to receive training in the activities affecting quality (see 5.8).
5.4 Inspection and testing
5.4.1 General
All necessary facilities, equipment and personnel shall be available to carry out the inspections and tests. The
manufacturer, or his representative, may employ, under contract, a subcontractor who has the facilities, equipment
and personnel to carry out the inspection and tests on behalf of the manufacturer. The manufacturer shall be
responsible for control, calibration, and maintenance of testing, measuring, and inspection equipment, whether
owned by or on loan to the manufacturer or a subcontractor.
Inspection and testing shall be performed by personnel qualified for such tasks on the basis of documented
appropriate education, training and/or experience.
Equipment shall be used in a manner that ensures that any measurement uncertainty is not greater than the required
measurement capability.
5.4.2 Test equipment
Tests to demonstrate conformity of the finished product to the relevant product standard shall be performed using
equipment in accordance with the test methods referred to in the product standard.
The test equipment shall be calibrated and/or checked against equipment or test specimens traceable to relevant
internationally or nationally recognised reference test specimens (standards). When no such reference test
specimens exist, the basis used for internal checks and calibration shall be documented. The reference test
specimens shall be calibrated as appropriate. The minimum frequencies of checks and calibrations for some test
equipment are given in Table 1. Test equipment not listed in Table 1 shall be checked and/or calibrated in
accordance with the manufacturer's documented procedures. The calibration records shall be maintained for a period
of 10 years.
NOTE Calibration may be carried out by any person experienced in the technology.
The manufacturer shall ensure that handling, preservation, and storage of test equipment is such that its accuracy
and fitness for use is maintained.

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.
5.4.3 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 supplied (often referred to as supplier certified components or
certified raw materials).
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.
5.4.4 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.
5.4.5 Product testing
5.4.5.1 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 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 5.4.5.2. 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 Annex, the testing frequency may be
lowered.
The testing frequency may be reduced to once a day, when for a given property, a highly controlled production
process is demonstrated by compliance with Equation (1).
|T| ≥ k(n) 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(n) is a factor corresponding to the number of test results available.
Table 2 gives the k factor corresponding to the two-sided 99 % tolerance interval with a confidence level of 99 %.

100 3,10
200 2,92
NOTE For other numbers of test results see ISO 3207:1975, 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.
5.4.5.2 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 re-examined 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.
5.4.6 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.
5.4.7 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.
5.5 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.
5.6 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.
5.7 Traceability of products
Individual products or product batches shall be identifiable and traceable with regard to their production origin.
5.8 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.
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).
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
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.
ITT will be performed by the approved body for all characteristics declared by the manufacturer. The number of test
results to be determined by the approved body is two except for reaction to fire characteristics and compressive
creep where only one test result is required.
As four test results are required for mechanical characteristics (excluding compressive creep), audit tests shall be
performed after one and two years in addition to the ITT thereby fulfilling the requirements in Annex C for ITT testing.
Sampling for initial type testing shall be carried out by the representative of the approved body, normally during the
initial inspection, with the manufacturer's representative present. The sample shall be taken from products identified
in accordance with 5.4.6 as conforming to the product standard (finished products ready for delivery). The sample
shall be taken at random and shall be representative of normal production and clearly identified to ensure that the
sample is used for testing. The representative of the approved body shall record the following details:
1) manufacturer name and address;
2) description of the product;
3) how the product is identified;
4) manufacturer's marking of the product;
5) inspection lot size;
6) sample size;
7) location and date of sampling;
8) all necessary information about the product for testing.
The record shall be agreed and signed by the representative of the approved body and the manufacturer’s
representative.
NOTE The minimum stock of products from which the sample is taken should be 10 m .
Unless otherwise specified, the sample shall be taken from four different production dates and shall, for factory made
products, cover the range of thickness declared by the manufacturer. One test result shall be determined for the
required characteristics on specimens from each production date. For reaction to fire characteristics only one test
result is required using test specimens from the different production dates.
All test results for each characteristic shall be better than or equal to the declared value.
A.2.4 Continuous surveillance
A.2.4.1 General
Production shall be subjected to continuous surveillance by an approved inspection body, consisting of routine
inspections (see A.2.4.2), audit testing (see A.2.4.3), actions in the case of nonconformity (see A.2.4.4) and
extraordinary inspections (see A.2.4.5).
The representative of the inspection body shall be allowed to enter the factory including the warehouse(s), without
announcement, at any time during the working hours in order to carry out the necessary works in connection with the
surveillance. He shall have access to all relevant information about the product in connection with the surveillance
and shall be provided with adequate assistance, particularly for sampling and testing.
The manufacturer shall inform the certification body of changes in the quality system that are (or might be) directly
connected to the conformity of the products.
A.2.4.2 Routine inspections
Routine inspections shall be performed to assess the continued conformity of the manufacturer's factory production
control system to the requirements of Clause 5. Reference shall be made to the records of the initial inspection
and/or previous routine inspections to ensure changes to the manufacturer's factory production control system are
assessed.
Records of inspections shall include details of the status of the factory production control system as it exists on the
date of the inspection.
During each routine inspection, the following shall be specifically examined:
1) results of the manufacturer's own testing to check:
a) that tests have been performed at the specified frequency and
b) that only products that have conformed to the product standard have been released;
2) that proper corrective actions have been taken when required;
3) calibration and maintenance of test equipment;
4) marking and labelling of products.
The results of the routine inspections shall be documented in a record of the inspection.
The routine inspections shall be performed twice a year, unless additional extraordinary inspections are carried out
according to B.2.4.4. The routine inspections shall be planned to ensure that all relevant functions of the
manufacturer are assessed during a prescribed period. The inspections shall aim at reflecting the normal working
manner of the factory. Inspections may be carried out without any previous announcement.
A.2.4.3 Audit testing
Audit samples shall be taken for checking conformity with the product standard. Samples shall be taken at random
normally during a routine inspection at the factory and they shall be representative of the normal production. Only if it
is agreed between the approved body and the manufacturer, shall samples be taken from elsewhere.
The representative of the approved body shall ensure that the manufacturer is aware of his responsibility to forward
the selected samples to the testing laboratory in proper condition and without undue delay.
Audit testing shall be conducted for the characteristics listed in Table A.1 at least once a year, except for the reaction
to fire and the lambda curve (for prEN 14303 through prEN 14309, prEN 14313, prEN 14314) , where the frequency
shall be once every 2 years. For each product group the approved body shall select one sample for test (from each
factory).
Audit testing shall only be performed for the characteristics from Table A.1 if they are declared.
Testing shall be carried out in accordance with the relevant product standard bearing in mind the number of tests
necessary to achieve one test result.
Where appropriate a comparison shall be made between the manufacturer's routine test results, results of witness
testing, and the results of testing by the approved body.
