Plastics piping systems for buried and above-ground drainage and sewerage under pressure - Unplasticized poly(vinyl chloride) (PVC-U) - Part 2: Guidance for the assessment of conformity CEN/TS 1456-2:2003

Publication date:   Oct 23, 2003

Scope

This Technical Specification gives guidance for the assessment of conformity intended to be included in the manufacturer's quality plan as part of the quality management system.
It includes:
a) requirements for materials, components, joints and assemblies given in EN 1456-1;
b) requirements for the manufacturer's quality management system;
NOTE 1 It is recommended that the quality management system conforms to EN ISO 9001 [1];
c) definitions and procedures to be applied if third party certification is involved.
NOTE 2 If third party certification is involved, it is recommended that the certification body is accredited to EN 45011[2] or EN 45012[3], as applicable.
In conjunction with EN 1456-1 it is applicable to PVC-U piping systems intended to be used for the conveyance of sewage and drainage under pressure at approximately 20 °C:
a) buried in the ground;
b) sea outfalls;
c) laid in inland waters and/or in ducts;
d) suspended below bridges.
This specification is also applicable to PVC-U piping systems for the continuous conveyance of sewage and drainage up to and including 45 °C as required in EN 773 [4].
NOTE 3 In this case the pressure derating factors given in Figure A.1 of EN 1452-2:1999 apply.
NOTE 4 No pressure reduction is necessary for the drainage of waste waters at short-term peak temperatures up to 45 °C (cumulated for 2 years during a service life of 50 years).
