47、e testing (ITT) and type testing (TT) 5.2.1 General Initial type testing and type testing shall be performed to demonstrate compliance of the products with the relevant specific product standards. All essential characteristics in bold in Table 1 for which the manufacturer declares performances, are
48、subject to initial type testing. In addition, the need to perform Type Tests applies to the characteristics according to 5.2.2 and 5.2.3 when the manufacturer claims compliance, unless the standard gives provisions (e.g. use of previously existing data, CWFT and conventionally accepted performance)
49、for declaring performances without performing tests. Tests previously performed in accordance with the provisions of this standard may be taken into account provided 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. ITT shall be performed at the beginning of the production of a ne
