8、has been prepared under the direction of the Textiles and Clothing Standards Committee. It is a revision of BS 5287:1976 which is withdrawn. Assessment of the behaviour of textile floor coverings tested in accordance with BS 4790 is valuable in determining the ease with which the textile floor cover
9、ing would ignite under practical conditions, e.g. when a burning cigarette, a hot coal, or a similar source of ignition is dropped on it. It is emphasized that the method of test described in BS 4790 is not intended to give an overall indication of the potential fire hazard presented by a textile fl
10、oor covering under actual conditions of use. Other methods of test, such as the radiant panel test 1)described in ASTM-E648:1978 2) , may be used to assess the performance of textile floor coverings in a fire situation. This test is intended to indicate the spread of flame under conditions of contro
11、lled heat flux and may lead to a further British Standard. In this revision two forms of giving information on the performance of textile floor coverings when tested according to BS 4790 are specified. In the first a pass criterion is specified for textile floor coverings for domestic use. In the se
12、cond three more detailed categories of performance for contract use are specified on the basis of the radius of the effects of ignition. Both forms of providing this information take account of the specimen mounting method used in the test. Information relating to the practical meaning of “radius of
13、 ignition” is given in Appendix A. As a result of these considerations, very careful attention should be given to the statement made on the textile floor covering label and in sales literature in regard to flammability. It should be simple, unambiguous and authoritative. A British Standard does not
14、purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside fro

16、oratory trial in ISO/TC38, as Draft Proposal9239. 2) Available from the Library, BSI, Linford Wood, Milton Keynes MK14 6LE.BS5287:1988 BSI 07-1999 1 1 Scope This British Standard specifies the form of assessment of the behaviour of textile floor coverings when subjected to the small source of igniti
17、on test described in BS 4790; and gives requirements for conveying the information obtained to domestic and contract users. It is applicable to all types of textile floor coverings used in the horizontal position. NOTE 1The test method described in BS 4790 is used in this standard to provide some as
18、sessment of the potential hazard of textile floor coverings being ignited from a small ignition source such as a lighted match, a burning cigarette or a glowing coal. In no circumstances should the test results thus obtained be used to assess the contribution the textile floor coverings will make to
19、 an established fire. NOTE 2The titles of the publications referred to in this standard are listed on the inside back cover. 2 Testing and labelling The textile floor coverings shall be tested in accordance with BS 4790 using the specimen mounting method 1, 2 or 3. The mounting method selected shall
20、 be the one which most closely resembles the method to be used for laying the textile floor covering. According to its observed behaviour under test, a specimen shall be considered satisfactory if the radius of the affected area is not greater than75mm. The minimum information to be given on the man
21、ufacturers label for domestic users shall be: For contract use the minimum information describing the observed behaviour under test shall be as given in Table 1. NOTEOther tests, such as the radiant panel test referred to in the foreword, may be used to provide additional information on the label. I
22、f both the area of the exposed use-surface and the area of the under-surface are measured in the test the greater of the two measurements shall be used to record the observed behaviour under test.

26、face of the material to be tested and the greatest radius of the effects of ignition from the point of application of the nut is measured both on the use-surface and on the under-surface. A result up to and including35mm, which can be described as “low radius of effects of ignition”, indicates that
27、if the material is ignited from a small source such as a lighted match or a glowing coal, it will not spread flame under normal conditions in the absence of supporting thermal radiation. A result greater than35mm and up to75mm, which can be described as “medium radius of effects of ignition”, indica
28、tes that if the material is ignited it will spread flame to a limited extent only. A result of over75mm, which can be described as “high radius of effects of ignition”, indicates that the material will ignite and may continue to spread flame.BS5287:1988 BSI 07-1999 Publications referred to BS 4790,
