those tests used for the purpose of the assessment of conformity. For each type of tests (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 and the frequency and sampling of testing.
A typical scheme for the assessment of conformity of compounds, products and assemblies by manufacturers
is given in Figure 1.

1 Scope
This Technical Specification gives guidance for the assessment of conformity of compounds/formulations,
products and assemblies in accordance with Parts 1 and 2 of EN 13598 intended to be included in the
manufacturer’s quality plan as part of the quality management system and for the establishment of third-party
certification procedures.
NOTE In order to help the reader, a basic test matrix is given in Annexes A and B.
In conjunction with EN 13598- 1 and -2, this Technical Specification is applicable to ancillary underground
drainage fittings including manholes and inspection chambers:
 for non-pressure underground drainage and sewerage outside the building structure (application area
code "U"), reflected in the marking of products by "U", and
 for non-pressure underground drainage and sewerage for both buried in 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".
