In addition initial type testing shall be performed at the beginning of the production of a new underlay 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). All characteristics in Clause 4 shall be subject to initial type testing, where relevant (see Table D.1). Whenever a change occurs in the underlay design, the raw material or supplier of the components, or the production process (subject to the definition of a family), which would change significantly one or more of the stated characteristics, the type tests shall be repeated for the appropriate characteristic(s). 6.2.2 Sampling Samples shall be taken according to EN 13416. The minimum number of tests to show compliance for initial and further type testing shall be one for all characteristics. 6.2.3 Test results The results of all type tests shall be recorded and held by the manufacturer for a period of at least 5 years. 6.3 Factory production control (FPC) 6.3.1 General The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market conform with the stated characteristics. The FPC system shall consist of procedures, regular 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. An FPC system conforming with the requirements of EN ISO 9001, and made specific to the requirements of this document, is considered to satisfy the above requirements. The results of 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. 6.3.2 Frequency of testing The rules for factory production control and verification of manufacturer’s values are given in Annex D. 7 Product data sheet and designation The characteristics of the product, determined in accordance with the test methods specified in this document, shall be listed in a technical data sheet.
