适用范围：1.1 This standard prescribes a method for the determination of flame resistance of textile floor coverings in a horizontal position when exposed to a small source of ignition under controlled laboratory conditions.1.2 The method is applicable to all types of textile floor coverings irrespective of their cons-truction or their fibre composition. The method may also be applicable to unfinished material.1.3 The results obtained on specimens in a hori-zontal position, as specified in this standard, do not apply to the behaviour of the textile floor covering when used in another position, parti-cularly in a vertical position.NOTE — The method should be used solely to assess the properties of materials or systems in response to heat and flame under controlled laboratory conditions and should not be used for the evaluation or regulation of the hazard of textile floor coverings under actual fire conditions. The method has been used extensively in the trade for acceptance testing and is considered satis-factory as a test for acceptance of merchandise, provided that an appropriate sampling plan such as given IS 7877 ( Part 1 ) : 1978. Methods of sampling and tests for hand made carpets: Part 1 Sampling and selection of areas of physical tests, is used.
