9、5-2-ENGL 1797 1bZL+bbS b57330 bLL BS EN IS0 10545-2 : 1997 National foreword This British Standard has been prepared by Technical Committee B/539 and is the English language version of EN IS0 105452 : 1997 CemmzC tiles - Part 2: Detmination of dimensions and su?fice quality, published by the Europea

10、n Committee for Standardization (CEN). It is technically equivalent to IS0 105452 : 1995, including its Technical Corrigendum 1 : 1997, published by the International Organization for Standardization (ISO). It supersedes BS 6431 : Part 10 : 1984, which will be withdrawn when Parts 1 to 16 of BS EN I

11、S0 10545 have all been published. This Part of BS EN IS0 10545 was originally drafted by CEN/rC 67, Ceramic tiles, as EN 98, published in 1984, and confirmed in 1991. Subsequently the European Standard was revised by IS0 as a Part of IS0 10545, which has now been approved by CEN as a Part of EN IS0

12、10545. The editorial modifications mentioned in the EN IS0 foreword have been made in this BS EN IS0 text. The technical changes from the method described in BS 6431 : Part 10 are as follows. For the measurement of straightness of sides, rectangular and surface flatness, a single diagrammatic figure

13、 replaces figures 1 and 2. The material of the calibrating plate for this measuring apparatus is not restricted to steel when measuring straightness and rectangulans. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprise
