Defines requirements for the materials, mechanical performance, dimensions, and effect on water quality of polyethylene pipes with an aluminium barrier layer, and associated fittings/joints for potable water supply installed in contaminated ground.

This British Standard specifies requirements for the materials, mechanical performance, dimensions, and effect on water quality of polyethylene pipes with an aluminium barrier layer, and associated fittings/joints for potable water supply installed in contaminated ground. It is applicable to TypeA and TypeB pipes with nominal sizes up to and including 630mm, with the following characteristics. TypeA: pipes where one or more polymer layers form a core pipe which is designed to bear the stresses associated with long term hydrostatic pressure, with the aluminium layer and outer polymer layer being barrier and protection layers respectively, and regarded as not bearing stresses arising from internal pressure. TypeB: pipes where one or more polymer layers and the aluminium layer bear the stresses associated with long term hydrostatic pressure. NOTE See 4.2 for pressure classes. This British Standard also covers the requirements for fittings and joints, manufactured by system manufacturers or others for use with one or more barrier pipe systems.
