21/30432484 DC

This standard 21/30432484 DC BS EN 12201-3. 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
• 23.040.45 Plastics fittings

This document specifies the characteristics of fittings made from polyethylene (PE) for buried and 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 1, 2, 4 and 5 of EN 12201, it is applicable to PE fittings, their joints and to joints with components of PE and 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.

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

These fittings can be of the following types:

1. fusion fittings;

   1. electrofusion fittings;

   2. spigot end fittings (for butt fusion using heated tools and electrofusion socket fusion);

   3. socket fusion fittings (see Annex A);

2. mechanical fittings;

   1. compression fittings;

   2. flanged fittings;

3. fabricated fittings (see Annex B).
