For each type of test
19、, i.e. type testing (TT), batch release test (BRT), process verification test (PVT), and audit test (AT), this document details the applicable characteristics to be assessed as well as the frequency and sampling of testing. A typical scheme for the assessment of conformity of materials, pipes, fitti

22、nd assemblies in accordance with the applicable part(s) of EN 12666 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 system confor
23、ms to or is no less stringent than the relevant requirements to EN ISO 9001:2008 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 readers, a summ
24、ary of the test regime is given in Annex A. In conjunction with EN 12666-1 (see Foreword) this document is applicable to piping systems made of polyethylene (PE): non-pressure underground drainage and sewerage outside the building structure (application area code “U“), reflected in the marking of pr
25、oducts by “U“, and for non-pressure underground drainage and sewerage for both buried in the ground within the building structure (application area code “D“) and outside the building structure (application area code “U“), reflected in the marking of products by “UD“. 2 Normative references The follo
