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).
