BS PD CEN/TS 1046:2021

This document gives the recommended practise for underground open trench installation and commissioning of thermoplastics piping systems to be used for the conveyance of water under pressure (in addition to EN 805) and for the discharge of wastewater under gravity (in addition to EN 1610).

In the field of non-pressure underground drainage and sewerage this is reflected in the marking of products by application code "U" and "UD":
— outside the building structure (U);
— both buried in ground within the building structure (application area code "D") and outside the building (application area code "UD").

This document covers also installation and/or connections to valves, manholes, inspection chambers, gullies and other ancillary components in piping systems.

All current amendments available at time of purchase are included with the purchase of this document.
