9、 D.2 Initial type testing Initial type testing shall be performed to show conformity with this European Standard. Tests previously performed in accordance with the provisions of this European Standard (same product, same characteristic(s), test method, sampling procedure, system of attestation of co
10、nformity etc.) may be taken into account. For the purposes of testing (including FPC testing), cast iron pipes and fittings, their joints and accessories may be grouped into families where it is considered that the selected property is common to all products within that family. Samples of prototypes
11、 (pipes, fittings, accessories and joints) for each range of DN (see Table 7) shall pass all the type tests listed in Tables 9 and 10 to demonstrate conformity with Clause 4, before production commences. In case of significant changes in design of the product and/or in manufacturing process, which w
12、ould change the properties of the finished product, the relevant type tests shall be repeated. All characteristics in Clause 4 shall be subject to initial type testing. NOTE In addition, the type tests in accordance with Annex D can be carried out by a competent laboratory accredited in accordance w
13、ith EN ISO/CEI 17011 and in conformity with EN ISO/IEC 17025 in order to demonstrate compliance with the requirements of this European Standard, retaining full reports of these type tests by the manufacturer and, where applicable, to be made available for examination.
