19、 Limited, under licence fromThe British Standards Institution, and came into effect on 30thApril 2016. It wasprepared by Subcommittee B/542/6, Corrugated sheeting materials, under theauthority of Technical Committee B/542, Roofing and cladding products fordiscontinuous laying. A list of organization
20、s represented on this Subcommitteecan be obtained on request to its secretary.SupersessionThis British Standard supersedes BS 5427-1:1996, which is withdrawn.Information about this documentThis is a full revision of the standard. It takes into account recent changes anddevelopments in materials, com
21、ponents, cladding systems and design practice,such as sheeting profiles, surface coatings, fixing systems, thermal insulation, theuse of liners, and alleviation of condensation.Use of this documentAs a code of practice, this British Standard takes the form of guidance andrecommendations. It should n
22、ot be quoted as if it were a specification andparticular care should be taken to ensure that claims of compliance are notmisleading.Any user claiming compliance with this British Standard is expected to be able tojustify any course of action that deviates from its recommendations.It has been assumed
23、 in the preparation of this British Standard that theexecution of its provisions will be entrusted to appropriately qualified andexperienced people, for whose use it has been produced.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Itsrecommendat
24、ions are expressed in sentences in which the principal auxiliaryverb is “should”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include a
25、ll the necessary provisions of acontract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legalobligations.BRITISH STANDARDBS 5427:2016iv The British Standards Institution 20161 ScopeThis British Standard gives recommendations for the
26、design and construction ofexternal cladding assemblies for roofs and walls of buildings in the UK, usinglongitudinally profiled sheeting as the external surface, including standing seam.It is not applicable to profiled sheeting used as a supporting substrate, decking,structural liner trays, fully su
27、pported profiled sheets, structural compositeformations of profiled metal sheeting and concrete, small element cladding orexceptional applications, such as buildings for cold storage.The principal profiled sheeting materials covered by this British Standard aresteel, aluminium, fibre cement, bitumen
28、 fibre and plastics, including insulatedsandwich panel assemblies of profiled sheeting, thermal insulation and linings.In addition to referencing performance recommendations, materials andcomponents identified by other British Standards, advice on other materialsand components which are in common us
29、e but not covered by other BritishStandards is also given.This British Standard is intended for use by designers, manufacturers andinstallers of the roofing products.This British Standard excludes profiled sheets used for structural purposes.2 Normative referencesThe following documents, in whole or
