Plastics piping systems for water supply and for buried and above-ground drainage and sewerage
under pressure ― unplasticized poly (vinyl
chloride) (PVC-U) Part 3: Fittings
Description
This part of ISO 1452 specifies the characteristics of fittings made from unplasticized poly(vinyl chloride) (PVC-U) for piping systems intended for water supply and for buried and above-ground drainage and
sewerage under pressure.
It also specifies the test parameters for the test methods referred to in this part of ISO 1452.
In conjunction with ISO 1452-1, ISO 1452-2 and ISO 1452-5, it is applicable to PVC-U fittings and to joints
with components of PVC-U, other plastics and non-plastics materials intended to be used for the following:
a) water mains and services buried in the ground;
b) conveyance of water above ground for both outside and inside buildings;
c) buried and above-ground drainage and sewerage under pressure.
It is applicable to fittings in piping systems intended for the supply of water under pressure up to and including
25 °C (cold water), intended for human consumption and for general purposes as well as for waste water
under pressure.
This part of ISO 1452 is also applicable to components for the conveyance of water and waste water up to
and including 45 °C. For temperatures between 25 °C and 45 °C, Figure A.1 of ISO 1452-2:2009 applies.
NOTE 1 The producer and the end-user can come to agreement on the possibilities of use for temperatures above
45 °C on a case-by-case basis.
Depending on the jointing method, this part of ISO 1452 is applicable to the following types of fittings:
⎯ fittings for solvent cementing;
PVC-U fittings can be manufactured by injection-moulding and/or be fabricated from pipe.
This part of ISO 1452 is also applicable to PVC-U flange adapters and to the corresponding flanges made
from various materials.
This part of ISO 1452 covers a range of fitting sizes and pressure classes and gives requirements concerning
colours.
NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects,
taking into account their particular requirements and any relevant national regulations and installation practices or codes.
