14、ven parts of the newly revised and restructured BS 6262.BS 6262:1982 is being revised and also restructured to simplify its use and will be published in seven parts: Part 1: General methodology for the selection of glazing; Part 2: Code of practice for heat, light and sound; Part 3: Code of practice

15、 for fire, security and wind loading; Part 4: Code of practice for safety related to human impact; Part 5: Code of practice for frame design considerations; Part 6: Code of practice for special applications; Part 7: Code of practice for provision of information.Requirements for standards of workmans

16、hip for glazing have been published separately 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, the recommendations in this part of the standard should be used in conjunc

17、tion with those in the other parts.As a code of practice, this British Standard takes the form of 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 p

21、 fire safety, security and wind loading.These recommendations apply only when the glass is installed in a glazing system specifically designed for the purpose.These recommendations do not apply to:a) patent glazing (see BS 5516-1);b) glass in non-vertical applications (see BS 5516-2)c) glazing for c

22、ommercial greenhouses (see BS 5502-21);d) glazing for domestic greenhouses.Requirements for standards of workmanship for glazing have been published separately as BS 8000-7 and, therefore, this subject is not dealt with in this standard.2 Normative referencesThe following referenced documents are in

42、8 October 2005Figure 1 Definition of sizeBS 6262-3:20054 Fire4.1 Regulations and test standardsStructural fire precautions might need to consider the performance of glass and plastics glazing sheet materials. These precautions are controlled for new building work by building regulations and bylaws a

43、nd by other fire safety legislation for occupied premises.For new buildings, control is exercised separately in England (excluding Inner London) and Wales, Inner London, Scotland and Northern Ireland. The extent of control depends on the type of glass or plastics glazing sheet material and the metho

44、d of specification, the particular location and the applicable regulations (see BS 6262-1:2005, Annex A) 1, 2, 3.In determining the appropriate fire properties of glazing the tests given in Table 1 apply. Both European Standards and British Standards are accepted, but these should not be mixed and m

45、atched.NOTE Building regulations generally only apply to the provision of reasonable standards of health and safety for people in buildings. Requirements other than regulatory ones (e.g. property protection) might need to be taken into account.Generally, regulations are written in terms of performan

46、ce under the standard fire tests but BS 5588 and other codes of practice dealing with means of escape in case of fire make specific mention in connection with the use of glass when fire resistance is required.Table 1 British and European StandardsBritish Standards European StandardsReaction to fireB

47、S 476-4:1970. This test determines whether building materials are non-combustible within the meaning of the definition. Determination of combustibility is made by reference to the duration of any flaming or the increase in the temperature of the sample or furnace above a defined limit.BS 476-6:1989.

48、 The tests provide a means of comparing the contribution of building materials to the growth of a fire by measuring the rate of heat evolution. The performance is expressed as a numerical index from 0 to 100 or more, low values indicating a low rate of heat release.BS 476-7:1987. The tests are used

49、to determine the tendency of materials to support the spread of flames across their surfaces and specifies a method of classification. The performances are expressed as four classes, class 1 representing the best performance.NOTE For Class 0, Tp(a) and Tp(b) see the appropriate building regulations 1, 2, 3.According to European Commission Decision 96/603/EC (consolidated 2003/424/EC)
