37、 i.e.BS 6859-1:1987 1) . 10 Information to be supplied by the manufacturer The manufacturer shall provide a statement of the attenuation of the table top. NOTERecommendations for radio-translucency of the table top are given in Appendix B. Table 1 Tests and requirements for paint and plastics coati
38、ng finishes 1) Marking BS 6859-1:1987 on or in relation to a product represents a manufacturers 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
39、person making the claim. Such a declaration is not to be confused with third party certification of conformity, which may also be desirable. Test Method Requirements 1. Bend test BS3900-E1 using the type2 apparatus and a6mm mandrel and burnished steel No cracks or loss of adhesion when examined with
40、 normal corrected vision 2. Scratch resistance BS3900-E2. Loaded with2 000g No bare metal visible 3. Impact resistance BS3900-E3. Indent to3mm No loss of adhesion 4. Cupping test BS3900-E4.

41、nBS6859-1:1987 4 BSI 11-1999 Appendix A Recommendations for design of mobile general operating tables A.1 Table base The base of the table should be designed to minimize obstruction to the feet and legs of the theatre staff. A.2 Floor loading Operating tables can impose heavy loads on floors, partic
42、ularly when used to transport patients within the operating department. To minimize wear to the floor, the wheels and/or castors should be of such numbers, dimensions and materials that will result in low static and dynamic pressure on floor surfaces commensurate with ease of mobility. Suspension ar
43、rangements of wheels and/or castors should ensure that all wheels and/or castors make full contact with floor surfaces whilst the table is being moved. A.3 Brake The release of the braking mechanism should not result in a significant uncontrolled drop in the height of the table top. Appendix B Recom
44、mendations for radio-translucency of the table top The table top, excluding the mattress, should have an attenuation equivalent 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
45、an X-ray source assembly operated at an X-ray tube voltage of100kV with a total filtration of2.5mm aluminium. The percentage ripple of the X-ray tube voltage should be less than10%.
