19、n of those tests used for the purpose of the assessment of conformity. For each type of test, 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 sampl

20、ing of testing. A typical scheme for the assessment of conformity of materials, pipes, fittings, joints or assemblies by manufacturers is given in Figure 1.

NOTE In order

23、to help the reader, a basic test matrix is given in Annex A. In conjunction with EN 14758-1 this document is applicable to solid wall piping systems made of polypropylene modified with mineral(s) (PP-MD) intended to be used for: non-pressure underground drainage and sewerage outside the building str

24、ucture (application area code “U”); and non-pressure underground drainage and sewerage for both buried in ground within the building structure (application area code “D”) and outside the building structure. This is reflected in the marking of products by “U” and “UD”. 2 Normative references The foll
