9、 the Building Services Standards Committee and was initiated by the Consumer Standards Advisory Committee, a need for such a standard having been indicated by various interested organizations. The use of a shower unit is now a widespread practice, and in many cases shower units can prove more conven
10、ient and economic than a bath. They also take up less space than conventional baths and are therefore beneficial in small flats or single person dwellings having limited floor area. They have special advantages for those who have difficulty in using a bath. Shower unit components may be purchased as
11、 individual items (e.g.shower tray, mixer valve), as groups of items (e.g.all brassware), and as complete pre-packed units ready for installing into the building. As a shower unit comprises many different components the consumer needs guidance on their choice and installation to ensure that the unit
12、, when installed, performs satisfactorily. In view of this many-faceted situation this standard is being published in the following Parts: Part 1: Guide on choice of shower units and their components for use in private dwellings; Part 2: Specification for the installation of shower units; Part 3: Sp
13、ecification for prefabricated shower enclosures; Part 4: Specification for shower heads; Part 5: Specification for prefabricated shower trays made from acrylic material; Part 6: Specification for prefabricated shower trays made from porcelain enamelled cast iron; Part 7: Specification for prefabrica
14、ted shower trays made from vitreous enamelled sheet steel; Part 8: Specification for prefabricated shower trays made from glazed ceramic. Components and installations that are not specific to shower units are covered in many other British Standards and these are referenced in this Part of this stand
15、ard. Reference is made in this standard to a number of British Standards which at the time of publication of this Part were still in draft form. As these documents are published, amendments will be issued giving the appropriate cross-references. In the meantime the purchaser should seek the advice o
16、f the manufacturer or installer on the topics not yet covered, in order to achieve an acceptable installation. 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 Britis
17、h 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, pages 1 and2, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments inco
18、rporated. This will be indicated in the amendment table on the inside front cover.BS6340-2:1983 BSI 07-1999 1 Section 1.
