A second revision was published in 1960 as CP 152 and this was subsequently revised in 1966, 1972 and 1982.The 1982 ed

38、ition of the code is currently 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

39、considerations; Part 6: Special 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has now been published and supersedes subclauses 4.7, 5.7, 6.7, Table 11, appendix A and Figures 43 and 44 which are withdrawn.The drawings contained

40、in this code are diagrammatic, 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

43、ernal walls and 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) b

Toleranc

45、es on glass thicknesses should be in accordance with BS 952-1.NOTE 2 It 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, shou

46、ld be reasonably applied.2 ReferencesThe titles of the publications referred to in this code are listed on the inside back cover.3 DefinitionsFor the purposes of this code the following definitions apply.3.1 aspect ratiothe ratio of the longer side of a pane to its shorter side3.2 back beddingthat p
