Many of the fabrics specif
11、ied in the 1967 edition of BS 1781 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 This new edition of BS 1781 supersedes the 1967 edition which is therefore withdrawn. Thi
12、s edition does not include any reference to standard patterns, which were formerly supplied by BSI as BS 1781P, 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 publi
13、cation of this British Standard it is proposed to formally withdraw BS 1781P. This standard does not specify requirements for the scale of sampling to be used. In appropriate cases guidance can be obtained from BS 6001. This standard has been produced following publication of BS 5815 and reference i
14、s made to that standard 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 confe
15、r immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 6, 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
16、in the amendment table on the inside front cover.
