Over deze norm
This document specifies the definitions and requirements for ancillary fittings and shallow chambers installed underground in non-pressure drainage and sewerage systems and manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) intended for use for: - non-pressure underground drainage and sewerage outside the building structure (application area code “U”), and - non-pressure underground drainage and sewerage for both buried in ground within the building structure (application area code “D”) and outside the building structure. This is reflected in the marking of products by “U” and “UD”. It also covers the jointing of the ancillary fittings and shallow chambers to the pipework system. The ancillary fittings covered by this standard are the following: - sealed access fittings; - rodding point covers; - rodding tees; - mechanical saddles. Ancillary fittings according to this document are intended for use in pedestrian or vehicular traffic areas. Ancillary fittings can be installed to a maximum depth of 6,0 m from ground level, with the exception of rodding point covers. Shallow chambers according to this document are intended for use in private drains located in pedestrian areas above the ground water table, to a maximum depth of 2,0 m from ground level to the invert of the main channel. This document covers shallow chambers with flow profile bases, and their joints to the piping system.
