1. Scope

This standard (Part 1) lays down requirements for buried polyethylene socket fittings using heated tools, where the shape and composition of the fitting is suitable for fusion with polyethylene pipes complying with IS 14885 : 2001 ‘Polythylene pipes for the supply of gaseous fuels - Specification’ and spigot fittings conforming to IS 15927 (Part 2) : 2010 ‘Polyethylene fittings for use with polyethylene pipes for the supply of gaseous fuels - Specification: Part 2 Spigot fittings for butt fusion, for socket fusion using heated tools and for use with electro fusion fittings’, for the supply of gaseous fuels for nominal outside diameters ranging from 16 mm to 125 mm with SDR 11 and SDR 17.6. Material grades PE 80 and PE 100, pressures 5.5 bar (see Note) and 7 bars and operating temperatures from - 5°C to 40°C.

NOTE - 1 bar = 10⁵ N/m² = 0.1 MPa.
