Sistemet e tubacioneve plastike për drenim dhe largimin e ujrave të zeza nën presion - Polivinil kloridi i pa plastifikuar ( PVC - U ) - Pjesa 1: Specifikime per pjeset perberese dhe sistemin

Plastics piping systems for buried and above-ground drainage and sewerage under pressure - Unplasticized poly(vinyl chloride) (PVC-U) - Part 1: Specifications for piping components and the system

Scope

This European Standard specifies requirements for unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of buried and above-ground drainage and sewerage under pressure.
In conjunction with one or more of Parts 1 to 5 of EN 1452 and ENV 1452-6, it is applicable to PVC-U pipes, fittings, valves and ancillary equipment, their joints and to joints with components of other plastics and non-plastics materials intended to be used for the conveyance of sewage and drainage under pressure at approximately 20 °C as follows:
a) buried in the ground;
b) sea outfalls;
c) laid in inland waters and/or in ducts;
d) suspended below bridges.
This standard is also applicable to components for the continuous conveyance of sewage and drainage up to and including 45 °C as required in EN 773 [1].
NOTE 1 In this case the pressure derating factors given in EN 1452-2:1999, Figure A.1 apply.
NOTE 2 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).
