Thermoplastics pipe and fitting systems for hot and cold water for domestic purposes and heating installations in buildings - Specification for crosslinked polyethylene (PE-X) pipes and associated fittings
This part of BS 7291 specifies general requirements and methods
of test for cross-linked polyethylene (PE-X) pipe and fitting systems
intended for use within buildings for the conveyance of cold water,
including drinking water, and heated water for use in domestic
hot and cold water distribution and heating installations. These
requirements supplement the general requirements in BS 7291-1
which are also applicable
This British Standard specifies general requirements for materials to
be used for or in the form of PE?X pipes, with or without a barrier
layer or associated fittings and components. Particular requirements
are also specified for PE-X pipe alone or jointed with push-fit and
compression fittings conforming to BS 7291 or other British Standards
intended for use with pipes conforming to this part.
This part of BS 7291 provides for pipes dimensioned to suit two
established metric series: BS ISO 4065 for thermoplastics pipes
generally and BS EN 1057 for compatibility with copper pipework
systems widely used for these applications.
