8 Evaluation of conformity
8.1 General
The compliance of a fire resisting duct section with the requirements of this European Standard shall be
demonstrated by:
initial type testing;
factory production control by the manufacturer, including product assessment.
8.2 Initial type testing
8.2.1 General
Initial type testing (ITT) shall be performed to demonstrate conformity of fire resisting ducts with this European
Standard.
All relevant characteristics of fire resisting ducts given in Clause 4 shall be subject to initial type testing to
enable classification as described in Clause 4. Tests shall be carried out in accordance with Clause 5. No fire
resisting duct sections needs to be re-tested for the sake of proving repeatability, but more than one fire
resisting duct section shall be required to be tested to cover different applications.
However, where a component of a fire resisting duct section is used, which is already shown to conform to
one or more of the requirements of this standard relevant for that component, the whole evaluation, which
leads to such conformity, shall not be required, but only those tests which have not been undertaken. Where
the component is used, for which the conformity could not be shown, the necessary evaluation to show this
shall be undertaken.
Because the objective of the general testing procedures is to establish the ability of the fire resisting duct
section to achieve the product design and performance requirements and classification in its operational
position (i.e. end use conditions), and to continue to act as a barrier for a designated period of time, the
complete product (i.e. including fixings) to be installed shall be tested.
8.2.2 Modifications
In the case of modification of the fire resisting duct section or of the method of production (where these may
affect the stated performance characteristics), the initial type testing shall also be performed. All
characteristics given in Clause 4, which may be changed by the modification, shall be subject to this initial
type testing.
8.2.3 Previous tests and product families
Tests previously performed in accordance with the provisions of this standard may be taken into account for
the ITT purpose providing that they were made to the same or a more rigorous test method under the same
system of attestation of conformity on the same product or products of similar design, construction and
functionality, such that the results are applicable to the product in question.
Products may be grouped into families where the results for one or more characteristics from any one product
in the family are representative for all other products within that family.
NOTE 1 Products may be in different families for different characteristics.
NOTE 2 Reference to the test methods standards should be made to allow the selection of a suitable representative
sample.

oSIST prEN 15871:2009
prEN 15871:2008 (E)
8.2.4 Test samples
Test samples of fire resisting duct sections shall be representative of the normal production.
If the technical documentation (see 6) of the test samples does not give a sufficient basis for later compliance
checks, a reference test sample (identified and marked) shall remain available for this purpose.
8.2.5 Test report
All initial type testing and its results shall be documented in a test report.
8.3 Factory product control (FPC)
8.3.1 General
The manufacturer shall establish, document and maintain an FPC system in a form of permanent internal
control of production to ensure that the fire resisting duct section placed on the market continuously conforms
with the ITT sample, for which compliance with this European Standard has been verified and expressed by
the fire resisting duct section’s stated performance characteristics.
The manufacturer shall always retain the overall control and shall have the necessary competence to take
responsibility for the fire resistance duct section.
If the manufacturer has the product designed, manufactured, assembled, packed, processed and labelled by
subcontracting, FPC of the original manufacturer may be taken into account. However, where subcontracting
takes place, the manufacturer shall retain the overall control of the products and ensure that he receives all
the information that is necessary to fulfil his responsibilities according to this European Standard. The
manufacturer, who subcontracts all of his activities, may in no circumstances pass his responsibilities on to a
subcontractor.
All the elements, requirements and provisions adopted by the manufacturer shall be documented in a
systematic manner in the form of written policies and procedures. This production control system
documentation shall ensure a common understanding of conformity evaluation and enable the achievement of
the required fire resisting duct section characteristics and the effective operation of the production control
system to be checked.
Factory production control, therefore, brings together operational techniques and all measures allowing
maintenance and control of the conformity of the product with this European Standard. Its implementation may
be achieved by controls and tests on measuring equipment, raw materials and constituents, processes,
machines and manufacturing equipment and finished products, including material properties in products, and
by making use of the results thus obtained.
8.3.2 General requirements
The FPC system shall fulfil the requirements as described in the following clauses of EN ISO 9001:2000,
where applicable:
4.2 except 4.2.1 a);
5.1 e), 5.5.1, 5.5.2;
Clause 6;
7.1 except 7.1 a), 7.2.3 c), 7.4, 7.5, 7.6;
8.2.3, 8.2.4, 8.3, 8.5.2.
11
---------------------- Page: 13 ----------------------
oSIST prEN 15871:2009
prEN 15871:2008 (E)
The FPC system may be part of a quality management system, e.g. in accordance with EN ISO 9001:2000.
8.3.3 Product specific requirements
The FPC system shall:
address this European Standard; and
ensure that the products placed on the market conform with the stated performance characteristics.
In addition to this, the manufacturer's FPC system shall contain a procedure that ensures that the fire resisting
duct section fulfil also the FPC supplemental requirements given in Annex C.
The FPC system shall include a product specific FPC- or quality-plan, which identifies procedures to
demonstrate conformity of the product at appropriate stages, i.e.:
a) the controls and tests to be carried out prior to and/or during manufacture according to a frequency laid
down; and/or
b) the verifications and tests to be carried out on finished products according to a frequency laid down.
If the manufacturer uses finished products, the operations under b) shall lead to an equivalent level of
conformity of the product as if normal FPC had been carried out during the production.
If the manufacturer carries out parts of the production himself, the operations under b) may be reduced and
partly replaced by operations under a). Generally, the more parts of the production that are carried out by the
manufacturer, the more operations under b) may be replaced by operations under a). In any case the
operation shall lead to an equivalent level of conformity of the product as if normal FPC had been carried out
during the production.
NOTE Depending on the specific case, it may be necessary to carry out the operations referred to under a) and b),
only the operations under a) or only those under b).
The operations under a) centre as much on the intermediate states of the product as on manufacturing
machines and their adjustment, and test equipment etc. These controls and tests and their frequency are
chosen based on product type and composition, the manufacturing process and its complexity, the sensitivity
of product features to variations in manufacturing parameters etc.
The manufacturer shall establish and maintain records, which provide evidence that the production has been
sampled and tested. These records shall show clearly whether the production has satisfied the defined
acceptance criteria. Where the product fails to satisfy the acceptance measures, the provisions for non-
conforming products shall apply, the necessary corrective action shall immediately be taken and the products
or batches not conforming shall be isolated and properly identified. Once the fault has been corrected, the test
or verification in question shall be repeated.
The results of controls and tests shall be properly recorded. The product descripti
