It supersedes BS 4660:1989 which is withdrawn. The nominal sizes of the fittings covered by this standar
9、d are 110 and 160, in accordance with BS 2782-11:Method 1121B:1998 (ISO 161-1:1996). The major changes between this edition and the previous edition are as follows. a) Pipes, bends, branches and couplers have been removed and are covered in BS EN 1401-1:1998. This edition specifies ancillary access
10、fittings not covered by BS EN 1401-1:1998. b) Dimensions and requirements for joint sockets, including seal-retaining components, have been clarified and the minimum wall thickness of sockets has been brought into line with BS EN 1401-1:1998. c) The title and scope have been modified, from “Unplasti
11、cized poly(vinyl chloride) (PVCU) fittings ” to “Thermoplastics ancillary access fittings ”, to recognize the fact that this standard does (and always has) specified some requirements for certain fittings of thermoplastics materials other than PVC-U. Annex A, which is normative, specifies a method o
12、f test for the impact resistance of polyolefin fittings. Annex B, which is normative, specifies a method of test for the water seal of a trapped gully. Annex C, which is informative, gives guidance on quality control testing. A bibliography is included. Attention is drawn to ENV 1401-3, BS 5955-6, B
13、S EN 1610 and BS EN 752, which give guidance on storage, handling and installation.
