Clause 4 is being deleted from th

9、e revision of BS1892-2.6:1972. This Section of BS 1892 applies to equipment for weight training or fitness training. Equipment for competition is not included and is subject to a specification laid down by the International Weight-Lifters Federation. The main change to this revision has been the inc

10、lusion of benches for use with weight training equipment together with stability and strength tests for benches. 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 Brit

11、ish Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages1 to 6, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments i
