BS 5852:2006 pdf download – Methods of test for assessment of the ignitability of upholstered seating by smouldering and flaming ignition sources 1 Scope This British Standard describes methods for assessing the ignitability of single material combinations, e.g. covers and fillings used in upholstered seating, or complete items of seating, when subjected either to a smouldering cigarette or to flaming ignition sources of thermal output ranging from that of a burning match to that approximating to the burning of four double sheets of full-size newspaper, as might be applied accidentally to any item of furniture. NOTE 1 It does not necessarily cover ignition caused by deliberate acts of vandalism with arson. The following methods are described: a) upholstered seating composites tested with flaming ignition sources (sources 2 to 7) (Clause 11); b) complete items of upholstered furniture tested with smouldering or flaming ignition sources (sources 0 to 7) (Clause 12). NOTE 2 Possible ways in which the standard can be used either to indicate the potential ignitability of components in conjunction with other specified materials or where more specific information is required about design features are given in Annex B. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
