10 Evaluation of conformity
10.1 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.
NOTEThe 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.
10.2 Initial type testing
10.2.1 Initial type testing shall be performed to demonstrate conformity with this European Standard.
All characteristics given in clauses 4, 5 and 6 shall be subject to this initial type testing, except as described in
10.2.3 to 10.2.5.
10.2.2 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 clauses 4, 5 and 6, which may
be changed by the modification, shall be subject to this initial type testing, except as described in 10.2.3 to 10.2.5.
Licensed Copy: London South Bank University, London South Bank University, Sat Jul 15 19:10:54 BST 2006, Uncontrolled Copy, (c) BSIEN 12094-1:2003 (E)
34
10.2.3 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.
NOTESame system of attestation of conformity means testing by an independent third party under the control of a product
certification body.
10.2.4 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.
10.2.5 Where the characteristics of the component have previously been demonstrated according to the
requirements of EN 54-2, EN 54-4 and EN 60529, no further evaluation of the component, in respect of these
characteristics, is required to show conformity with this European Standard.
10.2.6 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 manufact, urer.
NOTEIn 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 10.3),
it is verified that the component continuously complies with the initial type testing samples.
10.2.7 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.
10.2.8 Any initial type testing and its results shall be documented in a test report.
10.3 Factory production control (FPC)
10.3.1 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.
10.3.2 General requirements
The FPC system should fulfil the requirements as described in the following clauses of EN ISO 9001:2000, where
applicable:
4.2 except 4.2.1 a) Licensed Copy: London South Bank University, London South Bank University, Sat Jul 15 19:10:54 BST 2006, Uncontrolled Copy, (c) BSIEN 12094-1:2003 (E)

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.
10.3.3 Component specific requirements
10.3.3.1 The FPC system shall
address this European Standard; and
ensure that the components placed on the market conform with the stated performance characteristics.
10.3.3.2 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.
NOTEDepending on the specific case, it can 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 complexity, the 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 non-conforming 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.
10.3.3.3 Individual components or batches of components and the related manufacturing documentation shall
be completely identifiable and retraceable.

10.3.4 Initial inspection of factory and FPC
10.3.4.1 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.
10.3.4.2 The following shall be assessed to verify that the requirements of 10.3.2 and 10.3.3 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 10.3.4.1) available; and
b) that the FPC-procedures in accordance with the FPC-documentation are or will be (see 10.3.4.1) implemented
and followed in practice; and
c) that the component complies or will comply (see 10.3.4.1) 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 (see
10.3.2) 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.
10.3.4.3 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 10.3.4.2 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.
10.3.4.4 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.
NOTESame system of attestation of conformity means inspection of FPC by an independent third party under the control
of a product certification body.
10.3.4.5 Any assessment and its results shall be documented in a report.
10.3.5 Continuous surveillance of FPC
10.3.5.1 All factories which have been assessed according to 10.3.4 shall be re-assessed once a year, except
as stated in 10.3.5.2.
In this case each FPC assessment shall verify a different component or production process, where applicable.
10.3.5.2 If the manufacturer provides proof of continuing satisfactory operation of his FPC system the frequency
of the re-assessment may be reduced to once every four years.
NOTE 1Sufficient proof can be the report of a certification body, see 10.3.4.2 d).
NOTE 2If the overall Quality Management system in accordance with EN ISO 9001 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.

10.3.5.3 Any assessment and its results shall be documented in a report.
10.3.6 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.

Annex B
(informative)
Design requirements for software controlled e.c.d.
If a failure of program execution is detected, as specified in 6.3.1, the e.c.d. enters a safe state, as defined by the
manufacturer. It is expected that this safe state will not result in the false actioning of compulsory outputs, nor give
a false impression to a user that the e.c.d. remains operational if it is not.
It is accepted either to stop, or to automatically attempt to restart, the program execution. If there is a risk that
memory may have been corrupted, the restart procedure should check the contents of the memories, and if
necessary re-initialize running data to ensure that the e.c.d. enters a safe operating state.
Even if program execution is successfully restarted, it is important that the user is made aware of the incident. For
this reason it can be advantageous if the e.c.d. is capable of automatically recording details of the restart event. In
any event the fault indication of the failure of program execution will be latched until a manual intervention.
6.4.1 requires that all executable code and data necessary to comply with this standard will be held in memory
which is capable of continuous, unmaintained, reliable operation for a period of at least 10 years. In the existing
state of the art, memory with moving mechanical parts is not believed to be sufficiently reliable. The use of tapes, or
magnetic or optical data discs for the storage of programs and data is therefore not recommended at the time of
drafting this standard.
