This part of EN 1452 specifies the general aspects of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of water supply.
In conjunction with Parts 2 to 5 of EN 1452 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 following:
a) water mains and services buried in ground;
b) conveyance of water above ground for both outside and inside buildings;
for the supply of water under pressure at approximately 20 ℃ (cold water) intended for human consumption and for general purposes.
This standard is also applicable to components for the conveyance of water up to and including 45 ℃.
NOTE For temperatures between 25 ℃ and 45 ℃ figure A.1 given in annex A of EN 1452-2:1999 applies.
