7、echnical Specification (CEN/TS) was approved by CEN on 13 November 2015 for provisional application. The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their comments, particularly on the question whether the CEN/
8、TS can be converted into a European Standard. CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in paral
9、lel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

19、e 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 sampling of testing. A typical sc

23、 NOTE In order to help the reader, a basic test matrix is given in Annex A. In conjunction with EN 1852-1 this document is applicable to solid wall piping systems made of polypropylene (PP) intended to be used for: non-pressure underground drainage and sewerage outside the building structure (applic
24、ation 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 following document
