TS EN 1555-1

TS EN 1555-1 is the first part of the standard for plastics piping systems made of polyethylene (PE) intended for the supply of gaseous fuels. Rather than defining individual pipe dimensions or fittings, this part establishes the common technical framework for PE gas piping systems, so the related parts of the series can be read and applied consistently.

General framework for PE gas piping systems

PE is widely used in gas service because it is a thermoplastic with good flexibility, corrosion resistance and well-established joining techniques. In gaseous fuel applications, the key issues are material performance over time, pressure behaviour and the integrity of joints. This general part serves as the shared technical basis for that field, including the terminology and overall approach used across the series.

According to its scope, this part covers the general aspects of polyethylene piping systems in the supply of gaseous fuels. It also specifies the test parameters for the test methods referred to in the standard. In practice, that means the document helps align the conditions under which referenced tests are carried out, while the detailed test methods themselves belong to the cited standards.

How this part relates to the rest of the series

• The other parts of EN 1555 address specific components and application details within the same system family.
• This part acts as the common reference point for terminology and the basic technical framework.
• In gas piping, material selection, joining performance, pressure resistance and long-term behaviour are considered together.

This listing represents a withdrawn TS EN 1555-1 edition. Even so, it remains useful for understanding the technical relationships that underpin PE gas piping system design and assessment.
