This document specifies the characteristics of fusion fittings made from polyethylene (PE) as well as of mechanical fittings for piping systems in the field of the supply of gaseous fuels. It also specifies the test parameters for the test methods referred to in this document. In conjunction with EN 1555-1, EN 1555-2, EN 1555-4 and EN 1555-5, 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) a maximum operating pressure (MOP), up to and including 10 bar1, at a design reference temperature of 20 °C; b) an operating temperature between -20 °C and 40 °C. For operating temperatures between 20 °C and 40 °C, derating coefficients are defined in EN 1555-5. The EN 1555 series covers a range of MOPs and gives requirements concerning colours. This document is applicable for fittings of the following types: a) electrofusion socket fittings; b) electrofusion saddle fittings; c) spigot end fittings (for butt fusion using heated tools and electrofusion); d) mechanical fittings.
