The test method has been developed to fulfil the need for
11、 an accurate means of determining the dimensions of textile floor coverings using apparatus that is appropriate for use with test specimens or tiles. The dimensions of the principal items of apparatus are not, therefore, provided in view of the diversity of specimen sizes. A British Standard does no
12、t 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 f
13、ront cover, pages i and ii, pages 1 to 4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated.

It is applicable to t
15、extile floor coverings of all types, with maximum thickness 15 mm. NOTEThickness dimensions may be determined by the method described in BS 4051. 2 References The titles of the publications referred to in this standard are listed on the inside back cover. 3 Principle Dimensions along and across test
16、 specimens are measured using micrometer gauges. 4 Apparatus NOTEThis apparatus is suitable also for use in the methods for determination of dimensions of tiles described in BS 5921. The following apparatus is required. 4.1 A rigid, durable, smooth and waterproof baseboard, e.g. of metal or marine p
17、lywood coated with a plastics laminate, of a size suitable to accommodate the test specimen. Two stop bars, approximately 25 mm wide and 15 mm high, are fitted at right angles along two adjacent sides with a gap of approximately 1 mm at the corner. On each of the two opposite sides, two cut-outs or
18、slots are made approximately 20 mm wide and at least 20 mm long, to accommodate the presser feet of the dial gauge micrometers. The slots are positioned at % and b) the individual values, for each specimen, of the dimensions in the direction of manufacture and in the direction at right angles to the
19、 direction of manufacture to the nearest 0.1 mm; c) details of any deviations from the standard test procedure.
