1 Scope
This document specifies the characteristics of fusion fittings made from polyethylene
(PE) as well as of mechanical fittings for buried and above ground applications, intended for the conveyance of water for
human consumption, raw water prior to treatment, drains and sewers under pressure,
vacuum sewer systems, and water for other purposes, with the exception of industrial
application.
NOTE 1 For PE components intended for the conveyance of water for human consumption and raw
water prior to treatment, attention is drawn to subclause 6.6 of this document. Components manufactured for water for other purposes, drains and
sewers, and vacuum sewer systems are possibly not suitable for water supply for human
consumption.
NOTE 2 Industrial application is covered by EN ISO 15494 [4].
The intended uses include sea outfalls, laid in water and pipes suspended below bridges.
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with EN 12201‑1, EN 12201‑2, EN 12201‑4 and EN 12201‑5, this document is applicable to PE pipes, fittings and valves, their joints and joints
with components of PE and other materials intended to be used under the following
conditions:
a) allowable operating pressure, PFA, up to 25 bar 1 ;
