BS EN 1555-1:2021

This standard BS EN 1555-1:2021 Plastics piping systems for the supply of gaseous fuels. Polyethylene (PE) is classified in these ICS categories:

• 91.140.40 Gas supply systems
• 01.040.23 Fluid systems and components for general use (Vocabularies)
• 01.040.91 Construction materials and building (Vocabularies)
• 23.040.01 Pipeline components and pipelines in general

This document specifies the general aspects of polyethylene (PE) 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 Parts 2 to 5 of EN 1555 , this document is applicable to PE pipes, fittings, and valves, their joints and to joints with components of other materials intended to be used under the following conditions:

1. a maximum operating pressure, MOP, up to and including 10 bar ¹

   ¹

   1 bar = 0,1 MPa = 10 ⁵ Pa; 1 MPa = 1 N/mm ².

   at a reference temperature of 20 °C for design purposes;
   
   

2. an operating temperature between -20 °C and 40 °C.

EN 1555 (all parts) covers a range of maximum operating pressures and gives requirements concerning colours.
