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
ADOPTED_FROM:CEN/TS 1456-2:2003
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).
