What is BS EN 1555‑1 about?
BS EN 1555‑1 is the first part of the multi-series standard of European standards on ‘Plastic piping system and ducting system’. BS EN 1555. 1555‑1 specifies the general aspects of polyethylene (PE) piping systems in the field of the supply of gaseous fuels.
In conjunction with Parts 2 to 5 of EN 1555, BS EN 1555‑1 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:
- A maximum operating pressure, MOP, up to and including 10 bar1 at a reference temperature of 20 °C for design purposes
- An operating temperature between -20 °C and 40 °C.
Who is BS EN 1555‑1 for?
BS EN 1555‑1 on plastics piping systems is useful for:
- PE manufacturers and quality testing personnel
- Industries dealing with gaseous fuels such as mining, oil, and gas
- PE pipe specifiers and installers
Why should you use BS EN 1555‑1?
Piping systems are used to transport all known liquid or gaseous fluids, as well as pasty materials or pulp and fluids in suspension, over the entire pressure and temperature range used in industrial and residential applications. Their flexibility characteristics allow plastic pipes often to be changed around angles and obstructions without requiring extra joints and fittings.
With these features in mind, BS EN 1555-1 will help you build a safe and efficient piping system when it comes to supply of gaseous fuels.
BS EN 1555‑1 covers geometrical and material definitions for the manufacture of the compound, Polyethylene used in plastics piping systems for the supply of gaseous fuels which would make your piping system reliable and efficient.
Today, apart from its wide use in the oil and gas production industry, PE is also the material of choice for leak-free method of transporting natural gas to homes and industries. As the buyer of BS EN 1555-2, your business can be assured of best industry practice that will help build customer reliability and confidence and ease safety concerns.
What’s changed since the last update?
BS EN 1555‑1:2021 supersedes EN 1555-1:2010. BS EN 1555‑1:2021 includes some technical changes with respect to EN 1555-1:2010. These include:
- PE 100-RC type materials with enhanced resistance to slow crack growth have been added
- Annex A now discusses the performance of this type of material and gives additional information for nonconventional installation techniques
- The size range has been increased to 800 mm diameter
- Test methods have been updated
- New test methods have been added for PE 100-RC materials
