|Standard number:||21/30432490 DC|
|Status:||Draft for Comment|
This standard 21/30432490 DC BS EN 12201-5. Plastics piping systems for water supply, and for drainage and sewerage under pressure. Polyethylene (PE) is classified in these ICS categories:
- 23.040.20 Plastics pipes
This document specifies the characteristics of the fitness for purpose of the assembled piping systems intended for the conveyance of water intended for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes.
It also specifies the method of preparation of test piece joints, and the tests to be carried out on these joints for assessing the fitness for purpose of the system under normal and extreme conditions.
For PE components intended for the conveyance of water for human consumption and raw water prior to treatment attention is drawn to the introduction of this document. Components manufactured for water for other purposes are possibly not suitable for water supply for human consumption.
It specifies the test parameters for the test methods referred to in this document.
This document is intended only to be used by the product manufacturer to assess the performance of components according to prEN 12201‑2, prEN 12201‑3, or prEN 12201‑4 when joined together under normal and extreme conditions. It is not intended for on-site testing of pipe systems.
In conjunction with Parts 1 to 4 of prEN 12201 it is applicable to PE pipes, fittings, valves, their joints and to joints with components of other materials intended to be used under the following conditions:
allowable operating pressure, PFA, up to 25 bar1)1
) 1 bar = 0,1 MPa. = 105 Pa; 1 MPa = 1 N/mm2
an operating temperature of 20 °C as a reference temperature for design purposes;
buried in the ground;
laid in water;
above ground, including pipes suspended below bridges.
For applications operating at constant temperatures greater than 20 °C up to 40 °C, see prEN 12201‑1:2021, Annex A.
The EN 12201 series covers a range of allowable operating pressures and gives requirements concerning colours.
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 guidance or regulations and installation practices or codes.
