TS EN 1555-1

TS EN 1555-1. OFFICIAL SCOPE IS UNAVAILABLE. This standard belongs to the family of polyethylene (PE) plastics piping systems used for the supply of gaseous fuels, and it provides the general technical basis for that family. In practical terms, it helps frame the common terminology, general principles, and system-level context for PE pipes, fittings, and related components used in gas distribution networks. The appeal of PE in this field is generally linked to corrosion resistance, low weight, installation flexibility, and the suitability of fusion-type joining methods.

General context for PE gas piping systems

From an engineering perspective, PE piping is widely associated with buried gas networks and utility distribution work. Polyethylene behaves differently from metals, so design considerations typically include long-term stress behaviour, temperature influence, joining integrity, and overall system continuity. Standards in this area support consistent terminology and help ensure that components within the same product family are discussed and selected using the same technical framework.

What Part 1 means in this series

As Part 1, this document is the general part of the series rather than a component-specific product standard. Its value is in setting the common foundation for later parts that address particular pipe, fitting, or system requirements. For users, that means it is especially relevant as a reference for understanding the scope, terminology, and boundaries of the PE gas supply system family.

• Covers the general basis for PE piping systems for gaseous fuels.
• Polyethylene is a common plastic material in gas distribution infrastructure.
• Part 1 provides the shared technical framework for the series.
• General engineering topics include corrosion behaviour, flexibility, and joining methods.
