8、f BS6859 has been prepared under the direction of the Health Care Standards Committee at the request of the Department of Health and Social Security. BS6859 is published in two Parts, Part1 specifying requirements for mobile general operating tables. Attention is drawn to BS5724-2.22 which specifies
9、 requirements for safety of general operating tables. BS2891 which specifies requirements for operating table covers and pads is currently being revised. When the revision is published, clause8 of this Part of BS6859 will be amended to refer to it. Appendix A gives recommendations for design of tran
10、sporters which, although outside the scope of this Part of BS6859, 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 application. Complianc
11、e 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, pagesi andii, pages1 to6, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had am
12、endments incorporated. This will be indicated in the amendment table on the inside front cover.BS6859-2:1987 BSI 09-1999 1 1 Scope This Part of BS6859 specifies requirements for fixed-pedestal general operating tables with tops of four or more sections.

37、turers declaration of conformity, i.e.a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is therefore solely the responsibility of the person making the claim. Such a declaration is not to be confused with third party certif

41、se with removable table tops A.1 Transfer of the table top between the pedestal and transporter should be possible by manual control. A.2 The table top should be locked into the pedestal on takeover of the table top from the transporter. A.3 Any prepositioning of the patient or addition and fixation
42、 of accessories should not affect the stability of a transporter/top combination. A.4 Provision should be made to immobilize the transporter. A.5 To prevent damage to floors and to ensure ease of manoeuvring, the transporter should be fitted with large diameter wheels. A.6 Table tops, whilst located
43、 on their transporter, should be capable of achieving a Trendelenburg position see Figure 2(a) of not less than15 . A.7 The transporter should have cot sides. Appendix BRecommendations for radio-translucency of the table top The table top, excluding the mattress, should have an attenuation equivalen
44、t to no greater than1mm thickness of aluminium, determined from measurements of air Kerma under narrow beam conditions. The measurements should be made with X-radiation from an X-ray source assembly operated at an X-ray tube voltage of100kV with a total filtration of2.5mm aluminium. The percentage r
45、ipple of the X-ray tube voltage should be less than10%. NOTEThe break-back point need not be at the centre of the table top.
