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. This part of EN 1401 details the applicable
characteristics to be assessed as well as the frequency and sampling of testing for each type of test, i.e. type
testing (TT), batch release test (BRT), process verification test (PVT) and audit test (AT).
A typical scheme for the assessment of conformity of compounds/formulations, pipes, fittings, 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 EN 1401-1. It applies to those compounds/formulations, products
and assemblies 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 1 It is recommended that the quality management system conforms to or is no less stringent than the relevant
requirements of EN ISO 9001 [1].
NOTE 2 If third-party certification is involved, it is recommended that the certification body is accredited to either
EN 45011 [2], EN 45012 [3] or EN ISO/IEC 17021 [4], as applicable.
NOTE 3 In order to help the reader, a basic test matrix is given in Annex A.
In conjunction with EN 1401-1 (see Foreword), this Technical Specification is applicable to piping systems
made of unplasticized poly(vinyl chloride) (PVC-U) used for the following puposes:
 for non pressure underground drainage and sewerage outside the building structure (application area
code "U"), reflected in the marking of products by "U";
 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".

5 General
5.1 Materials, compounds/formulations, products, joints and assemblies shall conform to the requirements
given in EN 1401-1.
5.2 Products shall be produced by the manufacturer under a quality management system which includes a
quality plan (including specifications on joints and assemblies).
It is recommended that the quality management system conforms to or is no less stringent than the relevant
requirements to EN ISO 9001 [1].
6 Testing and inspection
6.1 Material specification
For the purposes of this Technical Specification, the material specification consists of a formulation which
defines PVC resin and additives and their dosage levels.
The dosage level of ingredients of a material shall not exceed the tolerance bands given in Table 1. If any
level exceeds the dosage band or if a type (see Table 1) is changed, this variation in formulation constitutes a
change in material.
The use of reprocessed and/or recycled material (which is referred to as "reprocessable and recyclable
material" in EN 1401-1 until further revision) shall be considered as a change in formulation when the change
in addition exceeds the tolerance bands given in Table 2.
The values of the parts X added to 100 parts by mass of PVC shall be specified by the manufacturer in the
quality plan.
