Introduction

This document is the specification for PE80 and PE100 spigot fittings and drawn bends in the nominal size range up to and including 1000 for use with PE80 and PE100 pipe and fittings, with nominal pressure ratings up to and including 16 bar. It supersedes WIS 4-32-04.

This specification has been prepared by WRc plc under the direction of the Water Industry Engineering and Operations Committee in consultation with the British Plastics Federation.
It should be noted that the range of spigot fittings of nominal size 20 to 63 are designed for use with electrofusion couplers conforming to WIS 4-32-14, and are not intended for butt fusion jointing.

Where possible, this specification has been harmonised with the draft CEN standard for plastics piping systems for water supply – Polyethylene (PE) – Part 3 Fittings.

The dimensions and pressure ratings of the pipes with which fittings manufactured in accordance with this specification are to be used, are based on BS 5556 and are given in WIS 4-32-03, WIS 4-32-09, WIS 4-32-13, and WIS 4-32-14.

WIS 4-32-08 covers site fusion jointing of PE80 and PE100. The WSA/WRc manual for polyethylene pipe systems for water supply offers guidance to the UK Water Industry on the practical design, installation and operation of PE water pipeline systems.
