Specifies requirements for macro-composite pipes and associated fittings for the conveyance of fluids including compressed air, gaseous fuels and water in agricultural, industrial, domestic and other applications in sizes ranging from 14 to 25 mm outside diameter. The macro-composite pipes covered by This Standard consist of a welded aluminium tube encapsulated in, and bonded to, an inner and an outer layer of polyethylene or cross-linked polyethylene.

This Standard specifies requirements for macro-composite pipes and associated fittings for the conveyance of fluids including compressed air, gaseous fuels and water in agricultural, industrial, domestic and other applications in sizes ranging from 14 to 25 mm outside diameter.The macro-composite pipes covered by this Standard consist of an aluminium core encapsulated in, and bonded to, an inner and an outer layer of polyethylene or cross-linked polyethylene.NOTE: Advisory information on the determination of compliance with this Standard is given in Appendix A.
