37、side back cover BS 6262:1982 BSI 09-2000v Foreword This code of practice was first published, as BS 973, in 1941 and revised under the same number in 1945. A second revision was published in 1960 as CP 152 and this was subsequently revised in 1966, 1972 and 1982. The 1982 edition of the code is curr
38、ently being revised under the direction of Technical Committee B/520 and will be published in seven Parts covering the following areas: Part 1: General; Part 2: Heat, light and sound; Part 3: Fire, security and wind loading; Part 4: Safety Human impact; Part 5: Frame design considerations; Part 6: S
39、pecial applications; Part 7: Provision of information. Part 4 which gives recommendations related to safety from human impact has now been published and supersedes subclauses 4.7, 5.7, 6.7, Table 11, appendix A and Figures 43 and 44 which are withdrawn. The drawings contained in this code are diagra
40、mmatic, their purpose being only to complement the text and indicate design principles. 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 British Standard does not of
41、itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i to vi, pages 1 to 84, an inside back cover and a back cover.

42、ng in this document indicates the most recent changes by amendment. vi blank BS 6262:1982 BSI 09-20001 1 Scope This code of practice gives recommendations for the design, installation and maintenance of vertically glazed (see 3.40) glass and plastics glazing sheet materials for the external walls an
43、d interiors of buildings. The recommendations in this code do not apply to: a) patent glazing (see BS 5516); b) glazing of furniture and fittings; c) glazing of barriers and balustrades (see BS 6180); d) glazing of commercial greenhouses (see BS 5502); e) glazing of domestic greenhouses; f) bent, pr
44、ofiled and corrugated glass; g) glass blocks; h) glass lens lights (precast and cast in situ); i) glass and plastics bullions; j) thermoformed plastics panels; k) corrugated plastics sheeting (reinforced and unreinforced). NOTE 1All dimensions given in this code for thickness are nominal. Tolerances
45、 on glass thicknesses should be in accordance with BS 952-1. NOTE 2It is not possible to state individual tolerances on all the installation dimensions contained in this code. These dimensions, which are based on considered good practice in the glazing industry and assume skilled workmanship, should
46、 be reasonably applied. 2 References The titles of the publications referred to in this code are listed on the inside back cover. 3 Definitions For the purposes of this code the following definitions apply. 3.1 aspect ratio the ratio of the longer side of a pane to its shorter side 3.2 back bedding
47、that portion of the glazing material between the face of the glass or plastics and the rebate upstand after the glass or plastics has been pushed into position NOTESee 3.4. 3.3 bead or glazing bead a strip of wood, metal or other suitable rigid material attached to the surround to retain the glass o
48、r plastics 3.4 bedding the glazing material placed in the rebate, into which the glass or plastics is bedded 3.5 blocks a) location blocks. Pieces of resilient material used between the edges of the glass or plastics (other than the bottom edge) and the surround to prevent relative movement between
49、the pane and the surround. b) setting blocks. Pieces of resilient material used between the bottom edge of the glass or plastics and the surround to support and centralize the pane in the surround. NOTESee also 3.11. 3.6 butt jointing the positioning of the edges of panes close together and the filling of the space between them 3.7 capping a sealant applied to fill the space remaining above a strip glazing material posi
