9、 Part of BS 6859 has been prepared under the direction of the Health Care Standards Committee at the request of the Department of Health and Social Security. BS 6859 is published in two Parts, Part 1 specifying requirements for mobile general operating tables. Attention is drawn to BS 5724-2.22 whic
10、h specifies requirements for safety of general operating tables. BS 2891 which specifies requirements for operating table covers and pads is currently being revised. When the revision is published, clause 8 of this Part of BS 6859 will be amended to refer to it. Appendix A gives recommendations for
11、design of transporters which, although outside the scope of this Part of BS 6859, may be used with certain tables which have removable tops. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct applica
12、tion. Compliance with a British 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, pages 1 to 6, an inside back cover and a back cover. This standard has been updated (see copyright date)
13、and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

14、s for fixed-pedestal general operating tables with tops of four or more sections. Fixed-pedestal operating tables intended for use with specialist procedures and accessories to tables are outside the scope of this Part of BS 6859, except that dimensions for accessory clamps have been specified to en
15、sure interchangeability of accessories between tables. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Dimensions and height NOTEFigure 1 shows schematic representations of a typical fixed-pedestal general operating table. 2.1 Table top The leng

22、m. 3.4 Lateral tilt see Figure 2(c) It shall be possible to tilt the table top laterally to either side to a position where the angle between the table top and the horizontal is at least 15 but does not exceed 20. 3.5 Break-back point see Figure 2(d) and Figure 2(e) At the break-back point, the tabl
23、e top shall be capable of flexion to 130 in any position where all sections are above the horizontal. The table top shall be capable of extension to an angle of not less than 220 between the upper surfaces when all sections are below the horizontal. 3.6 Chair or sitting position It shall be possible
24、 to adjust the sections of the table top to form a chair or sitting position. 3.7 Head section The head section shall be capable of adjustment through any angle between 45 1 downwards and 20 upwards.

25、ing the adjustment control. 3.8 Single leg section The leg section on tables with a single leg section shall be adjustable downwards through a minimum angle of 100. 3.9 Divided leg section The two leg sections on tables with a divided leg section shall be capable of rotation outwards in a horizontal
26、 plane to subtend an angle of not less than 100 and each shall also be independently adjustable downwards through a minimum angle of 100. 3.10 Detachable sections 3.10.1 In the case of tables with a single leg section, if the table top is not removable and both head and leg sections are detachable,
27、the head and leg sections shall be interchangeable. 3.10.2 Detachable sections shall not be removable without the release of a locating or locking device.
