8、 of technical Committee B/538, Doors, windows, shutters, hardware and curtain walling. a list of organizations represented on these committees can be obtained on request to their secretary.Supersessionthis part of BS 6375 supersedes BS 6375-2:1987, which is withdrawn.Relationship with other publicat
9、ionsBS 6375 is published in three parts:Part 1: Classification for weathertightness and guidance on selection and specification;Part 2: Specification for operation and strength characteristics;Part 3: Additional performance characteristics.it is related to the European product standard for windows a
10、nd pedestrian doors, BS En 143511)(see also Information about this document).Information about this documentthis is a full revision of the standard, and introduces the following principal changes.the standard now refers to European test methods and classes of performance. it identifies those perform
11、ance classes that are applicable to the UK market.tests previously required by PaS 23-1 for entrance doorsets have been included, although some minor changes to acceptable performance levels have been made. it is expected that PaS 23-1 will be withdrawn.BS 6375 has been prepared to provide advice on
12、 the selection of performance characteristics for windows and doorsets intended for the UK market. the full range of characteristics is also provided in the various parts of BS En 14351.BS En 14351 is the harmonized European Standard for windows and doors and is the standard that has to be reference
13、d if the product is to be CE marked. not all the characteristics listed in BS En 14351 are required for CE marking, and of those that are required, only those mandated (i.e. covered by national building regulations) in the UK need be declared.1)Only the first part of BS En 14351 has been published t
14、o date. Part 2 (Internal doors) and Part 3 (Resistance to fire and smoke) are still in preparation.BS 6375-2:2009iv BSI 2008BritiSh Standardthe majority of characteristics identified in BS En 14351 have a number of performance levels. BS 6375 provides guidance to the specifier and the manufacturer o
15、n an appropriate level for the UK market. this can be by a single value for a product characteristic or by a value for a particular service condition. For example, a doorset in a public building might need to meet a more severe level of performance for some characteristics than a doorset in a dwelli
16、ng.Specifiers are not obliged to use a particular performance level but need to be aware that unnecessarily selecting a more severe performance level can incur a cost penalty out of proportion to the performance advantage.BS En 14351 and BS 6375 cover a range of products and characteristics and are
17、therefore divided into parts. BS En 14351 is divided into product groups and BS 6375 is divided into performance characteristics. not all characteristics will be applicable to all product groups or to all end uses. in addition, BS 6375 may be used for product groups not covered by BS En 14351. BS 63
18、75 does not identify a recommended performance level for any characteristic that is recommended in national regulations (e.g. U values for windows); these levels are subject to statute.if a manufacturer wishes to declare a CE marked performance this has to be declared against the appropriate part of
19、 BS En 14351. Manufacturers wishing to CE mark products are advised to seek advice from the relevant national regulatory authority.this part of BS 6375 identifies in separate clauses the requirements that are applicable to windows and those that are applicable to doorsets.Presentational conventionst
20、he provisions of this standard are presented in roman (i.e. upright) type. its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative el

22、0091 ScopeBS 6375 is the national application document for BS En 14351 and identifies the characteristics and classes of performance appropriate for windows and internal/external pedestrian doorsets intended for the UK. it is applicable to both factory-glazed and site-glazed products.this part of BS
23、 6375 specifies performance requirements for the operation and strength of manually operated windows and internal/external pedestrian doorsets in their fully finished condition.2 Normative referencesthe following referenced documents are indispensable for the application of this document.

32、tics are necessary for every product or enduse situation. Characteristics should only be selected where the enduse situations make it necessary.NOTE 3 The order in which these characteristics are listed is not significant except that it maintains the order in which the characteristics are identified
33、 in BS EN 14351.NOTE 4 All the possible performance levels are given in BS EN 14351.NOTE 5 BS EN 14351 requires manufacturers to provide handling, installation, maintenance and care instructions with their products to ensure that all those characteristics required of a product are achieved.5 Perform

37、BS En 14609 for resistance to static torsion, the window shall meet the requirements of Class 3 as defined by BS En 13115:2001.5.2.2 RackingWhen tested in accordance with BS En 14608 for racking, the window shall meet the requirements of Class 3 as defined by BS En 13115:2001.5.3 Load-bearing capaci

39、 most unfavourable position and/or direction.5.4 Impact resistancethe recommended class for impact resistance for the UK is Class 0. if a higher class is declared, the window shall be tested in accordance with BS En 13049 and classified in accordance with table 2.NOTE 1 There are six classes of perf
40、ormance for this test, including a Class 0, but to date there is no experience in the UK of the effect of this test on windows, nor has any need for such a test been previously identified.NOTE 2 This test is used to assess the safe fixing of glass or other fragmental material in a window intended fo
41、r use at a level where protection is required from falling through to a lower level, e.g. windows at ground level externally providing light to a basement.NOTE 3 In view of the windows intended use (see Note 2) it might be necessary to carry out the test from both sides.table 2 Impact resistance for

45、uations, in buildings varying from entrance doors to shops, where little incentive to exercise care exists. To facilitate doorset performance selection, four classes of duty have been identified (see Table 3), against each of which the suggested level of performance has been given relative to each p
46、erformance characteristic.NOTE 2 Where an enhanced security characteristic (e.g. PAS 24) is required, the performance levels identified in this standard might be different. Reference should be made to the enhanced security standard for the appropriate levels of performance.table 3 Categories of use
