Products may be grouped into families where it is considered that a characteristic (or characteristics) is (are) common to all products within the family. 5.2 Type testing 5.2.1 Initial type testing Initial type testing shall be performed, to demonstrate conformity with this document, for each product type and for every significant change to a product type that may affect the performance of the product in relation to the requirements of this document. Test results or a declaration of conformity from a material (e.g. particleboard) supplier may be used to show compliance without additional testing. Changes in colour, pattern, surface texture and panel size are not considered to be significant changes.

EN 438-7:2005 (E) 12 Tests previously performed in accordance with the provisions of this document (same product, characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account. All characteristics in Clause 4 which are applicable to the product and the end use shall be subject to initial type testing. Whenever a change occurs in the raw material or the production process which would change significantly one or more of the characteristics, the type tests shall be repeated for the appropriate characteristic(s). 5.2.2 Sampling One or more panels (as required by the specified test methods) taken at random from normal production shall be used for initial type testing. In the case of Compact panels (for all characteristics except reaction to fire), testing of the thinnest and thickest laminates of the same type is sufficient to cover all intermediate thicknesses. For each characteristic, the lower performance achieved would apply. In the case of HPL composite panels (for all characteristics except reaction to fire), testing of the thinnest and thickest panels of the same composite construction (i.e. the same laminate type, adhesive type and substrate type) is sufficient to cover all intermediate thicknesses. For each characteristic, the lower performance achieved would apply. For reaction to fire see 4.2.1. The results of all type tests shall be recorded and held by the manufacturer for at least five years. 5.3 Factory production control (FPC) 5.3.1 General The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market conform with 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 incoming materials or components, equipment, the production process and the product. An FPC system conforming with the requirements of EN ISO 9001, and made specific to the requirements of this standard, is considered to satisfy the above requirements. The results of inspections, tests or assessments requiring action shall be recorded, as shall any action taken. The action to be taken when control values or criteria are not met shall be recorded. 5.3.2 Equipment All weighing, measuring and testing equipment shall be calibrated and regularly inspected according to documented procedures, frequencies and criteria. 5.3.3 Raw materials and components The specifications of all incoming raw materials and components shall be documented, as shall the inspection scheme for ensuring their conformity.
