21/30432478 DC

This standard 21/30432478 DC BS EN 12201-1. Plastics piping systems for water supply, and for drainage and sewerage under pressure. Polyethylene (PE) is classified in these ICS categories:

• 93.030 External sewage systems
• 91.140.60 Water supply systems
• 23.040.05 Pipelines and its parts for external sewage systems
• 23.040.20 Plastics pipes

This document specifies the general aspects of polyethylene (PE) pressure piping systems (mains and service pipes) for buried or above ground applications, intended for the conveyance of water 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 test parameters for the test methods referred to in this document.

In conjunction with Parts 2 to 5 of EN 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:

1. allowable operating pressure, PFA, up to 25 bar ¹⁾

   ¹

   ⁾ 1 bar = 0,1 MPa = 10⁵ Pa; 1 MPa = 1 N/mm².

   ;

2. an operating temperature of 20 °C as a reference temperature;

3. buried in the ground;

4. sea outfalls;

5. laid in water;

6. above ground, including pipes suspended below bridges.

EN 12201 series covers a range of allowable operating pressures and gives requirements concerning colours.
