8、mationThis British Standard was published by BSI and came into effect on 31 March 2006. It was prepared by Technical Committee FW/6, Flammability performance and fire testing. A list of organizations represented on this committee can be obtained on request to its secretary.SupersessionThis British S

9、tandard supersedes BS 6807:1996, which is withdrawn.Relationship with other publicationsThis British Standard extends the range of ignition sources provided by BS EN 597-1 and BS EN 597-2. It should be read in conjunction with BS EN 597-1 and BS EN 597-2 for the complete range of primary and seconda

10、ry ignition sources.Attention is drawn to BS 7177, which specifies requirements for the resistance to ignition of mattresses, divans and bed bases in various hazard classifications, when tested in accordance with this British Standard.Information about this documentThis is a full revision of the sta

11、ndard. The principal change is a clarification of progressive smouldering ignition; minor editorial changes have also been made.Tests for ignitability are usually carried out on a bare mattress, upholstered divan or upholstered bed base (see Clause 9). When different materials and products are place

12、d together the ignitability of the composite arrangement is highly dependent on the interactions between the components. For some end uses the bed assembly is already known, e.g. barracks, married quarters, hospitals and hotels, where the specifier is responsible for all the items which make up the

13、bed assembly. In these cases the mattress, upholstered divan or upholstered bed base and combinations thereof can be tested together with the respective bed covers (see Clause 10). The tests described in Clause 10 are intended solely for use where all the components of the complete bed assembly incl

14、uding sheets, etc. are known.It cannot be assumed that protection against large flaming ignition sources will automatically give protection against smouldering ignition. It is therefore necessary to submit test specimens to both cigarette tests and flaming ignition tests.Hazard warningsWARNING. Thes

15、e tests only relate to the ignitability of the materials described in the test report see Clause 12b) and Clause 12c) and are not intended to reproduce the full fire hazards that might be encountered.BS 6807:2006iv BSI 2006WARNING. This British Standard calls for the use of substances and/or procedu

16、res that can be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage.Presentational conventionsThe provisions of this standard are presented in roman (i.e. up

17、right) type. Its methods are expressed either as a set of instructions or 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 element.Contractual and legal cons

18、iderationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legal obligations.Attention is drawn to the following regulations: Furniture and Furnish

20、d describes methods for assessing the ignitability of mattresses, upholstered divans and upholstered bed bases when subjected to flaming types of primary and secondary ignition sources of differing severities.The following methods are described:a) mattress, upholstered divan or upholstered bed base

21、tested with primary ignition sources (Clause 9);b) mattress, upholstered divan or upholstered bed base and combinations thereof, tested with secondary ignition sources composed of known bed covers (Clause 10).2 Normative referencesThe following referenced documents are indispensable for the applicat

35、 practice it has been found that there is usually a clear distinction between materials that smoulder and char under the influence of the ignition source but that do not propagate further (non-progressive), and those where smouldering develops in extent and spreads (progressive).a) any test specimen

36、 that displays escalating smouldering combustion behaviour so that it is unsafe to continue the test and forcible extinction is required;b) for all ignition sources: any test specimen that smoulders until it is essentially consumed or that smoulders to the extremities of the specimen, i.e. to either

37、 side or to the full thickness of the specimen, within the duration of the test;c) for ignition sources 2 and 3: any test specimen that produces externally detectable amounts of smoke, heat or glowing 15 min after removal of the burner tube;d) for ignition sources 4, 5, 6 and 7: any test specimen th

38、at produces externally detectable amounts of smoke, heat or glowing 60 min after ignition of the crib;e) for top ignition only: any test specimen that on final examination (see Clause 11) shows evidence of smouldering by means of discoloured char that extends more than 100 mm in any horizontal direc

39、tion from the nearest part of the original position of the source.4.2 Flaming ignitionFor the purposes of this British Standard, all the following types of behaviour shall be deemed to be flaming ignition:a) any test specimen that displays escalating flaming combustion behaviour so that it is unsafe

40、 to continue the test and forcible extinction is required;b) any test specimen that burns until it is essentially consumed within the test duration;c) any test specimen on which any flame front reaches the extremities of the specimen other than the top or passes through the full thickness of the spe

41、cimen within the duration of the test. The exception is in the case of ignition from the side or below when the flame from the source reaches the top of the specimen during the course of the test and therefore this criteria does not constitute flaming ignition;d) for ignition sources 2 and 3: any te

42、st specimen that continues to flame for more than 120 s after removal of the burner tube;e) for ignition sources 4 and 5: any test specimen that continues to flame for more than 10 min after ignition of the crib; BSI 2006 5BS 6807:2006f) for ignition sources 6 and 7: any test specimen that continues

43、 to flame for more than 13 min after ignition of the crib;NOTE The times quoted in items e) and f) are essentially 2 min greater than the upper 95% probable extinction times of wood cribs determined by interlaboratory testing.g) for all sources: any test specimen from which debris causes an isolated

44、 floor fire not meeting the criteria of items d), e) or f).5 PrincipleA test specimen is subjected to a flaming ignition source placed on top of and below the test specimen.NOTE 1 The range of intensity of the primary sources has been selected to imitate that of actual sources which might be encount

45、ered in various end use environments, while the range of intensity of the secondary sources reproduces the effects of varying amounts and types of bed covers.NOTE 2 Ignition sources have been selected to supplement those in BS EN 597-1 and BS EN 597-2.NOTE 3 The tests can be used to assess the ignit

46、ability at any level but it is essential that the cigarette ignition specified in BS EN 597-1 is always included.6 Health and safety of operatorsWARNING. This British Standard calls for the use of substances and/or procedures that can be injurious to health if adequate precautions are not taken. It

47、refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage.NOTE 1 Suitable precautions might include the provision of breathing apparatus and protective clothing.NOTE 2 Attention is drawn to the Health and Safety at Work etc.

48、Act 1974 5 in respect of safety precautions.6.1 EnclosureThe tests shall be conducted in a suitable fume cupboard or purpose-built room so that individuals are not exposed to fumes (see 7.4).6.2 ExtinguishersReadily accessible means of extinguishing the test specimens shall be provided.NOTE 1 For pr

49、eference, water should be provided for smouldering fires and a fire extinguisher for flaming fires. Carbon dioxide extinguishers are not suitable for extinguishing smouldering test specimens.NOTE 2 Extinction of test specimens can be difficult and care should be taken that they are only disposed of when completely inert. It might be necessary to immerse smouldering specimens in water, or place them in a sealed non-combustible enclosure. To ensure complete safety other suitable steps might have t
