1 Scope
1.1 General
1.1.1 This Standard covers co‐extruded polyethylene/aluminium/polyethylene (PE‐AL‐PE) composite pipes comprising a welded aluminium (AL) tube laminated by a melt adhesive to two layers of polyethylene (PE) in nominal sizes 1216, 1620, 2025, 2532, 3240, 4050, 5063, 6375, 7590, and 90110 and specifies requirements for materials, physical characteristics, performance testing, and markings.
Note: The first two digits of the nominal size indicate the approximate inside diameter, in mm, and the following digits indicate the nominal outside diameter, also in mm. For example, a 2025 pipe means the inside diameter is approximately 20 mm and the outside diameter is approximately 25 mm.
1.1.2 PE‐AL‐PE composite pipes covered by this Standard are intended for use in
(a) residential and commercial water supply systems;
(b) residential heating systems; and
(c) compressed air systems.
1.1.3 PE‐AL‐PE composite pipes covered by this Standard are rated for
(a) 1,200 kPa a 23 ºC; and
(b) 600 kPa at 65 ºC.
1.1.4 This Standard does not cover
(a) PE‐AL‐PE composite pipes consisting of metallic layers not welded together; and
