It wasprepared by Sub

10、committee B/538/2, Doors, under the authority of TechnicalCommittee B/538, Doors, windows, shutters, hardware and curtain walling.

11、ithdrawn.Relationship with other publicationsThis British Standard is related to the following other standards. BS EN 14351-1 is the harmonized European product standard for windowsand external pedestrian doorsets without resistance to fire and smokeleakage characteristics. It gives a list of perfor

12、mance characteristics andclassifications of performance, but does not give guidance on determiningthe appropriate classification for any specific application. BS 6375 is the national application document in the UK, giving performancerequirements and guidance for the selection of appropriate classes

13、ofperformance from BS EN 14351-1. BS 8213-4 provides guidance on the survey and installation of replacementexternal pedestrian doorsets.Information about this documentThis is a full revision of the standard, and introduces the following principalchanges: changes taking into account the publication o

19、ves manufactured from steel skinswith a minimum thickness of 1.0 mm, where all surfaces are steel and the edgesare steel and mechanically fixed. It applies to doors whose leaves are infilledwith materials of either recycled cardboard honeycomb or mineral wool.It covers both complete doorsets, and do

20、or frames that could be used fordoorsets with non-metallic leaves.It applies to doors fitted into frames in a factory, to be installed vertically(within 15) into buildings, as single or double units, in coupled assemblies whenappropriate, of the following types:a) single leaf single-swing doors with

21、 or without side and over panels;b) double leaf single-swing doors with or without side and over panels;c) single leaf double-swing doors with or without side and over panels;d) double leaf double-swing doors with or without side and over panels.It is applicable to assemblies up to the point of inst

22、allation.This British Standard does not specify requirements for fire resistance or smokecontrol characteristics.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in thisdocument and are indispensable for its application.
