Where the requirements of ZA.3 give the same information as above, the requirements of this clause 6 have been met.

General

The compliance of the component with the requirements of this European Standard shall be demonstrated by:

 factory production control by the manufacturer.

The manufacturer, whether a natural or legal entity, is responsible for placing a component on the market under their own name Typically, the manufacturer designs and produces the component independently Alternatively, they may subcontract the design, manufacturing, assembly, packing, processing, or labeling of the component Additionally, they have the option to assemble, pack, process, or label pre-made products.

 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 is entirely accountable for ensuring that each component meets all applicable regulatory standards If the manufacturer utilizes components that have already been verified for compliance, such as those with CE marking, they are not obligated to conduct a new evaluation However, if the components have not been previously validated for conformity, the manufacturer must perform the necessary assessments to demonstrate compliance.

Initial type testing

7.2.1 Initial type testing shall be performed to demonstrate conformity with this European Standard.

All characteristics given in clause 4 (except 4.17) shall be subject to this initial type testing, except as described in 7.2.3 to 7.2.5.

In the event of modifications to the component or production method that could impact the specified properties, initial type testing is required This testing must cover all characteristics listed in clause 4, excluding 4.17, that may be altered by the modification, unless otherwise specified in clauses 7.2.3 to 7.2.5.

Tests conducted in accordance with this standard may be considered valid if they were performed using the same or a more stringent test method, under the same attestation of conformity system, and on components of similar design, construction, and functionality, ensuring that the results are relevant 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.

Components can be categorized into families based on shared characteristics or representative test results Consequently, it is not necessary to test every component within a family for initial type testing.

If the component's characteristics have already been validated in accordance with prEN 12094-4 and EN 60529, no additional assessment is necessary to confirm compliance with this European Standard.

In the context of prototypes and third-party certification, the manufacturer is responsible for selecting the samples, not the third party During the initial factory inspection and production control, it is confirmed that the component consistently meets the standards of the initial type testing samples.

7.2.7 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.

7.2.8 Any initial type testing and its results shall be documented in a test report.

Factory production control (FPC)

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.

When a manufacturer outsources the design, production, assembly, packaging, processing, and labeling of a component to a subcontractor, the subcontractor's FPC can be considered However, the manufacturer must maintain overall control of the component and ensure they obtain all necessary information to meet their obligations under the European Standard It is crucial to note that a manufacturer cannot absolve themselves of responsibility by subcontracting all activities.

FPC is the permanent internal control of production exercised by the manufacturer.

Manufacturers must systematically document all elements, requirements, and provisions through written policies and procedures This documentation of the production control system is essential for ensuring a shared understanding of conformity evaluation, facilitating the achievement of necessary component characteristics, and enabling effective monitoring of the production control system's operation.

Factory production control integrates operational techniques and measures to ensure that components meet technical specifications This process involves conducting controls and tests on measuring equipment, raw materials, manufacturing processes, machines, and finished products By analyzing the results obtained from these evaluations, manufacturers can maintain and verify the conformity of material properties in components.

The FPC system should fulfil the requirements as described in the following clauses of EN ISO 9001:2000, where applicable:

The FPC system may be part of a Quality Management system, e.g in accordance with EN ISO 9001.

 address this European Standard; and

 ensure that the components placed on the market conform with the stated performance characteristics.

The FPC system must incorporate a specific FPC or Quality plan that outlines procedures for demonstrating component conformity at various stages This includes controls and tests to be conducted before and during manufacturing at specified frequencies, as well as verifications and tests on finished components, also according to established frequencies.

When finished components are utilized by the manufacturer, the processes outlined in section b) will ensure that the component achieves a conformity level equivalent to that obtained through standard FPC during production.

When a manufacturer conducts parts of the production process independently, it can reduce the operations typically required under category b) and substitute them with those under category a) Generally, a higher degree of self-conducted production allows for more operations under b) to be replaced by those under a) Regardless of the approach taken, the operations must ensure that the component achieves a conformity level equivalent to that obtained through standard Factory Production Control (FPC) during 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 focus on the intermediate states of components, as well as the manufacturing machines, their adjustments, and measuring equipment The selection of controls, tests, and their frequency is determined by factors such as the type and composition of the component, the complexity of the manufacturing process, and the sensitivity of component features to variations in manufacturing parameters.

The manufacturer must maintain records that demonstrate the sampling and testing of production, clearly indicating whether it meets the established acceptance criteria, and these records should be kept for a minimum of ten years In cases where components do not meet acceptance measures, non-conforming product procedures must be followed, requiring immediate corrective action, isolation, and proper identification of the non-conforming components or batches After addressing the issue, the relevant tests or verifications must be repeated.

All control and test results must be accurately documented, including the component description, manufacturing date, adopted test method, test results, and acceptance criteria, all signed by the responsible individual If any control result fails to meet the requirements of the European Standard, the records must also detail the corrective actions taken, such as conducting additional tests, modifying the manufacturing process, or discarding or repairing the component.

7.3.3.3 Individual components or batches of components and the related manufacturing documentation shall be completely identifiable and retraceable.

7.3.4 Initial inspection of factory and FPC

Initial inspections of the factory and the FPC typically occur while production is ongoing and the FPC is actively implemented However, these inspections can also be conducted prior to the commencement of production and the practical application of the FPC.

7.3.4.2 The following shall be assessed to verify that the requirements of 7.3.2 and 7.3.3 are fulfilled:

The factory assessment must confirm that all necessary resources for meeting the component characteristics outlined in this European Standard are available or will be available Additionally, it should ensure that the FPC procedures, as detailed in the FPC documentation, are being implemented and adhered to in practice.

The component must comply with the initial type testing samples verified against the European Standard Additionally, it is essential to determine if the Factory Production Control (FPC) system is integrated into a Quality Management System that adheres to EN ISO 9001 standards This system should be certified and undergo annual surveillance by a recognized certification body, which is a member of the European Co-operation for Accreditation and has signed the Multilateral Agreement (MLA).

All manufacturing facilities where final assembly or testing of components occurs must be evaluated to ensure compliance with specified conditions A single assessment can encompass multiple components, production lines, or processes If the Factory Production Control (FPC) system applies to various components and meets the general requirements, then the detailed verification of the FPC requirements for one component can serve as a representative for others.

Assessments conducted under this standard can be considered if they pertain to the same conformity attestation system and involve the same component or components with similar design, construction, and functionality, ensuring that the results are relevant 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.

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

7.3.5.1 All factories which have been assessed according to 7.3.4 shall be re-assessed once a year, except as stated in 7.3.5.2.

In this case each FPC assessment shall verify a different component or production process, where applicable.

7.3.5.2 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 1 Sufficient proof can be the report of a certification body, see 7.3.4.2 d).

If the Quality Management system aligns with EN ISO 9001 and is effectively implemented and maintained, as confirmed by initial assessments and ongoing QM audits, it indicates that the relevant aspects of the integrated Factory Production Control (FPC) are adequately addressed Consequently, this ensures that the manufacturer's operations are well-regulated, allowing for a reduction in the frequency of special FPC surveillance assessments.

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