BS 1555-1:2010 pdf download – Plastics piping systems for the supply of gaseous fuels — Polyethylene (PE) Part 1 : General 1 Scope This part of EN 1555 specifies the general aspects of polyethylene (PE) piping systems in the field of the supplyof gaseous fuels. lt also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 2 to 5 of EN 1555 it is applicable to PE pipes fittings, and valves, their joints and tojoints with components of other materials intended to be used under the following conditions: a) a maximum operating pressure,MOP, up to and including 10 bar 1); b) an operating temperature of 20 °C as reference temperature. NOTE1 For other operating temperatures, derating coefficients should be used, see EN 1555-5[6]. EN 1555 (all parts) covers a range of maximum operating pressures and gives requirements concerning coloursand additives. NOTE2 lt is the responsibility of the purchaser or specfier to make the appropriate selections from these aspects, takinginto account their particular requirements and any relevant national regulations and installation practices or codes.
