12、 The recommendations for the co-ordination of dimensions in building as laid down in BS2900 “Recommendations for the co-ordination of dimensions in building. Glossary of terms”, and BS4011 “Recommendations for the co-ordination of dimensions in building. Basic sizes for building components and assem
13、blies” are embodied where appropriate in this standard. The metric values are given in SI units; for further information reference should be made to BS3763 “The International System of units (SI)” and PD5686, “Theuse of SI units”. The revision of this British Standard has been aimed at retaining the
14、 main dimensions of the previous issue, but allowing manufacturers freedom of design within these requirements. To this end the dimensions have been listed in tabular form and any illustrations likely to be misconstrued as indicating design have been eliminated. The materials known as stoneware and
15、earthenware have been omitted as they are no longer used in an appreciable quantity. The British Standards dealing with the quality of material, and finish, of vitreous china, taps and wastes suitable for these wash basins are as follows: BS504, Drawn lead traps. BS1010, Draw-off taps and stopvalves
16、 for water services (screwdown pattern). BS1184, Copper and copper alloy traps. BS3380, Wastes for sanitary appliances and overflows for baths Part 1. Wastes (excluding skeleton sink wastes) and bath overflows. BS3402, Quality of vitreous china sanitary appliances. BS3943, Plastics waste traps. Cert

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a Br
18、itish Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1to4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments inc
