This document specifies the characteristics of pipes made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels. NOTE 1 Additional information related to the installation of PE 100-RC systems is given in EN 1555-1:2025, Annex A. NOTE 2 Additional information about the suitability of PE pipe systems for hydrogen and its admixtures is given in EN 1555-1:2025, Annex B. It also specifies the test parameters for the test methods referred to in this document. In conjunction with EN 1555-1, EN 1555-3, 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 bar 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 specified in EN 1555-5. The EN 1555 series covers a range of MOPs and gives requirements concerning colours. This documen
