13、authority of the Mechanical Engineering Industry Standards Institution. It is based upon proposals prepared by the Association of Hydraulic Equipment Manufacturers and forms an essential part of the metrication programme of the fluid power industry. It is published in association with BS 5200 “Dimen
14、sions of hydraulic hose connectors and adaptors”. 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 legal obli
15、gations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 4, 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 on
16、the inside front cover.

17、ulic fluid power applications. The long tangent elbows are suitable for the manufacture of compression fittings; the 55 mm radius elbow has been excluded for this application. It is the responsibility of the purchaser to ensure that the remaining dimensions not specified in this standard, the materi
18、als and the production processes, compatible with both service pressure and fluids, are stated in the purchasing contract. 2 Reference The title of the British Standard referred to in this standard is given on the inside back cover. 3 Dimensions 3.1 The envelope dimensions for 90 short tangent elbow
19、s shall be as detailed in Table 1. 3.2 The envelope dimensions for 90 long tangent elbows shall be as detailed in Table 2. 3.3 The envelope dimensions for 135 short tangent elbows shall be as detailed in Table 3. 3.4 The envelope dimensions for 135 long tangent elbows shall be as detailed in Table 4
