PD CEN/TS 1455-2:2012CEN/TS 1455-2:2012 (E) 4 Introduction Figures 1 and 2 are intended to provide general information on the concept of testing and organisation of those tests used for the purpose of the assessment of conformity. For each type of test, i.e. type test (TT
21、), batch release test (BRT), process verification test (PVT) and audit test (AT), this document details the applicable characteristics to be assessed and the frequency and sampling of testing. A typical scheme for the assessment of conformity of materials (compounds/formulations), pipes, fittings, j
22、oints or assemblies by manufacturers is given in Figure 1.

Figure 2 Typical scheme for the assessment of conformity by a manufacturer, including a third-party certification PD CEN/TS 1455-2:2012CEN/TS 1455-2:2012 (E) 5 1 Scope This Technical Specification gives guidance for the assessment of conformity of materials (c
24、ompounds/formulations), products and assemblies in accordance with EN 1455-1 intended to be included in the manufacturers quality plan as part of the quality management system and for the establishment of third-party certification procedures. NOTE 1 It is recommended that the quality management syst
25、em conforms to or is no less stringent than the relevant requirements to EN ISO 9001 1. NOTE 2 If third-party certification is involved, it is recommended that the certification body is accredited to EN 45011 2, EN 45012 3 or EN ISO/IEC 17021 4, as applicable. NOTE 3 In order to help the reader, a b
26、asic test matrix is given in Annex A. In conjunction with EN 1455-1, this document is applicable to solid-wall piping systems made of acrylonitrile-butadiene-styrene (ABS) intended to be used for the following purposes: for soil and waste discharge (low and high temperature) inside buildings (applic
27、ation area code “B“); for soil and waste discharge (low and high temperature) inside buildings and buried in ground within the building structure (application area code “BD“). NOTE 4 This is reflected in the marking of products by “B“ or “BD“. 2 Normative references The following documents, in whole
