Many of the fabrics specified in the1
10、967 edition of BS1781 for sheets, sheeting, pillowslips and miscellaneous cloths have been deleted since they are no longer purchased in sufficient quantities to justify inclusion in this revision. This new edition of BS1781 supersedes the1967 edition which is therefore withdrawn. This edition does
11、not include any reference to standard patterns, which were formerly supplied by BSI as BS1781P, and could be used to assess properties not specified in the standard. Standard patterns may now be available from the purchasing authority mentioned in the tender or contract, and on publication of this B
12、ritish Standard it is proposed to formally withdraw BS1781P. This standard does not specify requirements for the scale of sampling to be used. In appropriate cases guidance can be obtained from BS6001. This standard has been produced following publication of BS5815 and reference is made to that stan
13、dard for dimensions of sheets, sheeting and pillowslips. A British Standard does not 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 leg
14、al obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 to6, 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
