This part of BS 5516, together with BS 5516-1, supersedes BS 5516:1991, which is withdrawn. It revises al
16、l or part of Clauses 6, 7, 10.3 to 10.5, 10.6.2, 10.6.3, 10.8, 12, 14 to 19, 20.1, 20.3, 20.4, 21 to 24, 25.1, 25.2, 25.4, 25.6, 25.8, 25.9, 26 to 29, and Annex A to Annex F and Annex J to Annex K of BS 5516:1991. BS 5516:1991 has been revised and restructured to simplify its use and will be publish
17、ed in three parts covering the following areas: Part 1: Code of practice for design and installation of sloping and vertical patent glazing; Part 2: Code of practice for sloping glazing; Part 3: Special applications. Requirements for standards of workmanship for glazing have been published separatel
18、y as BS 8000-7 and, therefore, this subject is not dealt with in this standard. Since the correct selection of materials to be used in glazing for buildings depends on many factors, attention is drawn to the other parts of this standard. As a code of practice, this British Standard takes the form of
19、 guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its corr
20、ect application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and iv, pages 1 to 83 and a back cover. The BSI copyright notice displayed in this document indicates

It includ
22、es those situations where the sloping glazing extends down to floor level. These recommendations apply only when the glass is installed in an appropriate glazing system. These recommendations do not apply to: a) vertical glazing (see BS 6262); b) glazing for commercial greenhouses (see BS 5502-21);
23、c) glazing for domestic greenhouses; d) sloping glazing which is to be used as a walking surface (see BS 5516-3); e) profiled plastics sheets. NOTE There are occasions, as with some curved glazing, where parts of a pane might be vertical, while other parts might be sloping. In this case, attention i
24、s drawn to both BS 6262 and BS 5516. Requirements for standards of workmanship for glazing have been published separately as BS 8000-7 and, therefore, this subject is not within the scope of this standard. Since the correct selection of materials to be used in glazing for buildings depends on many f
25、actors, attention is drawn to the recommendations in the other parts of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
