7、 2016. Itwas prepared by Subcommittee B/538/1, Windows and Doors. A list oforganizations represented on this subcommittee can be obtained on request toits secretary.SupersessionThis British Standard supersedes BS 4873:2009, which is withdrawn.Relationship with other publicationsThe requirements and
8、properties for aluminium window and door extrusions arespecified in BS EN 755-1, BS EN 755-2, BS EN 755-9, BS EN 12020-1 andBS EN 12020-2.This British Standard also relates to the following standards.a) BS EN 14351-1 is the harmonized European product standard for windowsand external pedestrian door
9、sets without resistance to fire and smokeleakage characteristics. It gives a list of performance characteristics andclassifications of performance, but does not give guidance on determiningthe appropriate classification for any specific application.b) The BS 6375 series are the national application
10、documents in the UK, givingperformance requirements and guidance for the selection of appropriateclasses of performance from BS EN 14351-1.c) BS 8213-4 provides guidance on the survey and installation of windows andexternal pedestrian doorsets.Information about this documentThis is a full revision o
11、f the standard, and introduces changes which take intoaccount:a) the development of window and doorset design; andb) the publication of new and revised European Standards.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Itsrequirements are express
12、ed in sentences in which the principal auxiliary verb is“shall”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Requirements in this standard are drafted in accordance with Rules for thestructure and drafting of
13、 UK standards, subclause J.1.1, which states,“Requirements should be expressed using wording such as: When tested asdescribed in Annex A, the product shall .”. This means that only those productsthat are capable of passing the specified test will be deemed to conform to thisstandard.Contractual and
14、legal considerationsThis publication does not purport to include all the necessary provisions of acontract. Users are responsible for its correct application.BRITISH STANDARDBS 4873:2016ii The British Standards Institution 2016Compliance with a British Standard cannot confer immunity from legaloblig

16、ows and external pedestrian doorsets,thermally or non-thermally improved, including constituent materials andglazing.This British Standard does not apply to composite doorsets as defined inBS 8529, but it does cover doorsets that are predominantly aluminium framed(stile and rail construction) with r
17、eplaceable composite panels.This British Standard applies to windows and doorsets fabricated in a factory, tobe installed vertically (15) into the external face of buildings, as single ormulti-light units, or in coupled assemblies where appropriate, of the followingtypes:a) windows:1) hinged: side-h
18、ung, top-hung, bottom-hung, tilt before turn or turnbefore tilt;2) projecting: side-hung and top-hung (including reversible windows);3) pivoted: horizontal and vertical;4) sliding: horizontal and vertical (including tilting-in sash to vertical);5) fixed lights;6) fixed casement;7) parallel opening;8
19、) double opening French casement;9) louvred, adjustable;b) doorsets:1) single leaf, single-swing or double-swing hinged or pivoted doors withor without side lights and top lights;2) double leaf, single-swing or double-swing hinged or pivoted doors withor without side lights and top lights;3) sliding
20、 doors (includes tilt and slide and lift and slide doors);4) sliding folding doors.This British Standard is applicable to windows in which a casement or sash framemember is no longer than 3 m and in which a door leaf frame member is nolonger than 3.5 m. This British Standard does not apply to curtai
21、n walls thatspan across horizontal structural members of floors, but it is applicable towindows or doorsets fitted within a curtain walling system.This British Standard is not applicable to secondary windows applied to convertexisting single windows into double or coupled windows.NOTE Guidance on th
