The test method has been developed to fulfil the need for an accurate
10、 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 not purport to
11、 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 front cover,
12、pagesi andii, pages1 to4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS5920:1980 BSI 11-1999 1 1 Scope This British Standard specifies a m
13、ethod for the determination of dimensions of textile floor covering test specimens for use in the dimensional stability test methods described in BS4682. It is applicable to textile floor coverings of all types, with maximum thickness15mm. NOTEThickness dimensions may be determined by the method des
14、cribed in BS4051. 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 specimens are measured using micrometer gauges. 4 Apparatus NOTEThis apparatus is suitable also for use in the methods for dete
15、rmination of dimensions of tiles described in BS5921. The following apparatus is required. 4.1 A rigid, durable, smooth and waterproof baseboard, e.g.of metal or marine plywood coated with a plastics laminate, of a size suitable to accommodate the test specimen. Two stop bars, approximately25mm wide
16、 and15mm high, are fitted at right angles along two adjacent sides with a gap of approximately1mm at the corner. On each of the two opposite sides, two cut-outs or slots are made approximately20mm wide and at least20mm long, to accommodate the presser feet of the dial gauge micrometers. The slots ar
17、e 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 direction of manufacture to the nearest0.1mm; c) details of any deviations from the standard test procedure.4 blankBS5920:1980 BSI 11-1999
