BS 4660:2022 发布历史

1   Scope This British Standard specifies requirements for ancillary fittings of nominal sizes 110 and 160 installed underground in non‑pressure drainage and sewerage systems, manufactured from unplasticized poly(vinyl chloride) ( PVC-U ), polypropylene ( PP ), polypropylene with mineral modifier ( PP -MD) or polyethylene ( PE ) and intended for use for: a) non‑pressure underground drainage and sewerage outside the building structure (application area code “U”); and b) non‑pressure underground drainage and sewerage both buried in ground within the building structure (application area code “D”) and outside the building structure. NOTE This is reflected in the marking of products by “U” and “UD”. This British Standard also covers the jointing of the ancillary fittings to the pipework system. The ancillary fittings, which are designed to be buried in the ground, can be installed to a maximum depth of 6.0 m from the ground level (with the exception of gullies and channel fittings ) and are intended for use in pedestrian and vehicular trafficked areas. The ancillary fittings covered in this British Standard are:
