5 Evaluation of conformity
5.1 General
The compliance of the component with the requirements of this European Standard shall be demonstrated by:
initial type testing;
factory production control by the manufacturer.
NOTE The manufacturer is a natural or legal person, who places the component on the market under his own name.
Normally, the manufacturer designs and manufactures the component himself. As a first alternative, he may have it
designed, manufactured, assembled, packed, processed or labelled by subcontracting. As a second alternative he may
assemble, pack, process, or label ready-made products.
The manufacturer shall ensure:
• that the initial type testing in accordance with this European Standard is initiated and carried out
(where relevant, under the control of a product certification body); and
• that the component continuously complies with the initial type testing samples, for which compliance
with this European Standard has been verified.
He shall always retain the overall control and shall have the necessary competence to take the responsibility
for the component.
The manufacturer shall be fully responsible for the conformity of that component to all relevant regulatory
requirements. However, where the manufacturer uses components already shown to conform to those
requirements relevant for that component (e.g. by CE marking) the manufacturer is not required to repeat the
evaluation which led to such conformity. Where the manufacturer uses components not already shown to
conform, it is his responsibility to undertake the necessary evaluation to show conformity.
5.2 Initial type testing
5.2.1 Initial type testing shall be performed to demonstrate conformity with this European Standard.
All characteristics given in Clause 4 shall be subject to this initial type testing, except as described in 5.2.3 to
5.2.5.
5.2.2 In the case of modification of the component or of the method of production (where these may affect
the stated properties), initial type testing shall be performed. All characteristics given in Clause 4, which may
be changed by the modification, shall be subject to this initial type testing, except as described in 5.2.3 to
5.2.5.
5.2.3 Tests previously performed in accordance with the provisions of this standard may be taken into
account 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 component or components of similar design, construction and
functionality, such that the results are applicable to the component in question.
NOTE Same system of attestation of conformity means testing by an independent third party under the control of a
product certification body.
5.2.4 Components may be grouped into families where one or more characteristics are the same for all
components within that family or the test results are representative of all components within that family. In this
case, not all components of the family have to be tested for the purposes of the initial type testing.
5.2.5 Test samples shall be representative of the normal production. If the test samples are prototypes, they
shall be representative of the intended future production and shall be selected by the manufacturer.
NOTE In the case of prototypes and third party certification, this means that it is the manufacturer not the third party
who is responsible for selecting the samples. During the initial inspection of the factory and of the factory production
control (see 5.3), it is verified, that the component continuously complies with the initial type testing samples.
5.2.6 If the technical documentation of the test samples does not give a sufficient basis for later compliance
checks, a reference sample (identified and marked) shall remain available for this purpose.
5.2.7 Any initial type testing and its results shall be documented in a test report.
5.3 Factory production control (FPC)
5.3.1 General
The manufacturer shall establish, document and maintain an FPC system to ensure that the components
placed on the market conform with the stated performance characteristics.
If the manufacturer has the component designed, manufactured, assembled, packed, processed and labelled
by subcontracting, FPC of the subcontractor may be taken into account. Where subcontracting takes place,
the manufacturer shall retain the overall control of the component 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 discharge himself of his
responsibilities to a subcontractor.
FPC is the permanent internal control of production exercised by the manufacturer.
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 component 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 component with its technical specifications. Its
implementation may be achieved by controls and tests on measuring equipment, raw materials and
constituents, processes, machines and manufacturing equipment and finished components, including material
properties in components, and by making use of the results thus obtained.
5.3.2 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.
The FPC system may be part of a Quality Management system, e.g. in accordance with EN ISO 9001:2000.
5.3.3 Product-specific requirements
5.3.3.1 The FPC system shall:
address this European Standard; and
ensure that the components placed on the market conform with the stated performance characteristics.
5.3.3.2 The FPC system shall include a component specific FPC- or Quality-plan, which identifies
procedures to demonstrate conformity of the component 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 components according to a frequency laid
down.
If the manufacturer uses finished components, the operations under b) shall lead to an equivalent level of
conformity of the component 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 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 component 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 component as on manufacturing
machines and their adjustment, and measuring equipment etc. These controls and tests and their frequency
are chosen based on component type and composition, the manufacturing process and its complexitythe
sensitivity of component 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 and shall be available at least for ten years. Where the component fails to satisfy the
acceptance measures, the provisions for nonconforming products shall apply, the necessary corrective action
shall immediately be taken and the components 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 component description, date of manufacture,
test method adopted, test results and acceptance criteria shall be entered in the records under the signature
of the person responsible for the control/test. With regard to any control result not meeting the requirements of
this European Standard, the corrective measures taken to rectify the situation (e.g. a further test carried out,
modification of manufacturing process, throwing away or putting right of the component) shall be indicated in
the records.
5.3.3.3 Individual components or batches of components and the related manufacturing documentation
shall be completely identifiable and retraceable.
5.3.4 Initial inspection of factory and FPC
5.3.4.1 Initial inspection of factory and FPC shall generally be carried out when the production is already
running and the FPC is already in practice. It is, however, possible that the initial inspection of factory and
FPC is carried out before the production is already running and/or before the FPC is already in practice.
5.3.4.2 The following shall be assessed to verify that the requirements of 5.3.2 and 5.3.3 are fulfilled:
the FPC-documentation; and
the factory.
In the assessment of the factory it shall be verified:
a) that all resources necessary for the achievement of the component characteristics required by this
European Standard are, or will be, (see 5.3.4.1) available; and
b) that the FPC-procedures in accordance with the FPC-documentation are, or will be, (see 5.3.4.1)
implemented and followed in practice; and
c) that the component complies, or will comply, (see 5.3.4.1) with the initial type testing samples, for which
compliance with this European Standard has been verified; and
d) whether the FPC system is part of a Quality Management system in accordance with EN ISO 9001:2000
(see 5.3.2) and as part of this Quality Management system is certified and has yearly surveillance by a
certification body, who is recognised by an accreditation body which is member of the "European Co-
operation for Accreditation” and which has signed the “Multilateral agreement” (MLA) there.
5.3.4.3 All factories of the manufacturer, where for the relevant component final assembling or at least
final testing is performed, shall be assessed to verify that the conditions of 5.3.4.2 a) to c) are in place. One
assessment may cover one or more components, production lines and/or production processes. If the FPC
system covers more than one component, production line or production process, and if it is verified that the
general requirements are fulfilled then the detailed verification of the component specific FPC requirements for
one component may be taken as representative of the FPC of other components.
5.3.4.4 Assessments previously performed in accordance with the provisions of this standard may be
taken into account providing that they were made to the same system of attestation of conformity on the same
component or components of similar design, construction and functionality, such that the results may be
considered applicable to the component in question.
NOTE Same system of attestation of conformity means inspection of FPC by an independent third party under the
control of a product certification body.
5.3.4.5 Any assessment and its results shall be documented in a report.
5.3.5 Continuous surveillance of FPC
5.3.5.1 All factories which have been assessed according to 5.3.4 shall be reassessed once a year,
except as stated in 5.3.5.2.
In this case, each FPC assessment shall verify a different component or production process, where applicable.
5.3.5.2 If the manufacturer provides proof of continuing satisfactory operation of his FPC system the
frequency of the reassessment may be reduced to once every four years.
NOTE 1 Sufficient proof can be the report of a certification body, [see 5.3.4.2 d)].
NOTE 2 If the over all Quality Management system in accordance with EN ISO 9001:2000, is well implemented
(verified in the initial assessment of factory and FPC) and continuously practised (verified in QM-audits), it can be
assumed that the integrated FPC-relevant part is well covered. On this basis, the work of the manufacturer is well
controlled, so that the frequency of special FPC-surveillance-assessments can be reduced.
5.3.5.3 Any assessment and its results shall be documented in a report.
5.3.6 Procedure for modifications
In the case of modification of the component, the method of production or the FPC system (where these may
affect the stated properties), a re-assessment of the factory and of the FPC system shall be performed for
those aspects which may be affected by the modification.
Any assessment and its results shall be documented in a report.

Fire exposure test for body and cover
NOTE See 4.4.1.2 requirements.
A.1 Procedure
Mount the deluge valve, without trim and with body openings sealed, horizontally as shown in Figure A.1. Fill
the pipework and valve between valves 3 and 4 with water. Close valve 3 and open valve 4.
Position the fire tray, having surface area not less than 1 m , centrally beneath the deluge valve. Place
° °
sufficient volume of suitable fuel in the tray to give an average air temperature between 800 C and 900 C
°
around the valve for a period of at least 15 min after a temperature of 800 C is reached.
Measure the temperature with two thermocouples positioned diametrically opposite and 10 mm to 15 mm from
the surface of the deluge valve on a horizontal plane parallel to the axis at the mid-point between the
mounting connections.
° °
Ignite the fuel and after (15 ± 1) min exposure at 800 C to 900 C remove the fire tray or extinguish the fire.
Starting within 1 min of extinction, cool the deluge valve by flushing with (100 ± 5) l/min of water for a period of
at least 1 min. Dismantle the valve to expose the sealing assembly and manually check whether or not the
sealing assembly opens freely and fully.
