The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the product.
6.2 Initial type testing
6.2.1 General
Initial type testing shall be performed to demonstrate compliance with this European Standard.
Tests previously performed In accordance with the provision 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 product or products of similar design, construction and functionality such that the results are applicable to the product in question.
NOTE 1 Same system of attestation of conformity means testing by an independent third party under the responsibility of a product certification body.
For the purpose of testing (including factory production control testing). products may be grouped into families where it is considered that the results for one or more characteristics from any one VAD of the family are representative for all the VAD within that family.
NOTE 2 Products may be in different families for different characteristics.
NOTE 3 Reference to the test method standards should be made to allow the selection of a suitable representative sample.
In addition, initial type testing shall be performed at the beginning of the production of a new VAD type (unless a member of the same family) or at the beginning of a new method of production (where this may affect the stated properties).
Where components are used whose characteristics have already been determined by the component manufacturer, on the basis of conformity with other product standards, these characteristics need not be reassessed. The specifications of these components shall be documented, as shall the inspection scheme for ensuring their conformity.
Products CE marked in accordance with appropriate harmonised European specifications may be presumed to have the performances stated with the CE marking, although this does not replace the responsibility on the manufacturer to ensure that the VAD is correctly designed and its component products have the necessary performance values to meet the design.
All essential characteristics for which the manufacturer declares performances, are subject to initial type testing. Whenever a change occurs In the VAD design, the raw material or supplier of the components, or the production process (subject to the definition of a family), which would affect significantly one or more of the characteristics, the type tests shall be repeated for the appropriate characteristic(s).
The manufacturer shall establish, document and maintain a factory production control (FPC) system to ensure that the products placed on the market comply to the stated performance characteristics.
The FPC system shall consist of procedures, regular Inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product.
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 product 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 compliance of the product with this technical specification.
6.3.2 General requirements
6.3.2.1 General
The manufacturer is responsible for organising the effective implementation of the factory production control system. Tasks and responsibilities in the production control organisation shall be documented and this documentation shall be kept up—to-date.
In each factory the manufacturer may delegate the action to a person having the necessary authority to:
— identify procedures to demonstrate conformity of the product at appropriate stages:
— identify and record any instance of non-conformity:
— identify procedures to correct instances of non conformity.
The manufacturer shall draw up and keep up-to-date documents defining the factory production control which he applies. The manufacturer’s documentation and procedures should be appropriate to the product and manufacturing process. All FPC systems should achieve an appropriate level of confidence in the conformity of the product. This involves:
a) the preparation of documented procedures and instructions relating to factory production control operations, in accordance with the requirements of the reference technical specification (see 6.3.1);
b) the effective Implementation of these procedures and instructions;
C) the recording of these operations and their results;EN 54-23-2010 pdf download.
