TS EN 1555-1

TS EN 1555-1 is the general part of the standard series for polyethylene (PE) piping systems used in the supply of gaseous fuels. It sets out the common framework for PE-based gas piping systems and their components, and it also specifies the test parameters used for the test methods referenced in the standard. In practice, this kind of document helps align terminology, product families, and verification conditions across the wider gas piping standard series.

General framework for PE gas piping systems

Polyethylene is widely used in gas distribution because it combines low weight, corrosion resistance, and practical processability for pipe manufacture and installation. In gas service, the key technical concerns are long-term material behaviour, pressure performance, and compatibility of joints and components. TS EN 1555-1 is the general section of the series, so it provides the shared technical basis that supports the more specific product and component standards in the other parts of EN 1555.

Main technical areas covered by the standard

• General aspects of PE piping systems for the supply of gaseous fuels
• Test parameters needed for the test methods referred to in the standard
• A shared technical basis and terminology for use with the rest of the series
• A general framework for performance evaluation of PE-based piping systems

The standard is focused on PE piping systems for gas service, so it should not be read as a document for water, wastewater, or generic plastic piping applications. It is also not a product installation manual; rather, it defines the system family and provides the basis for how the referenced tests are parameterized. For engineers, manufacturers, and test laboratories working with gas piping, its main value is that it creates a common technical starting point for the more detailed parts of the series.
