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,

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
