9、01-2000 National foreword This British Standard has been prepared under the direction of the Health Care Standards Policy Committee and is the English language version of EN 61168:1994 Radiotherapy simulators Functional performance characteristics, published by the European Committee for Electrotech
10、nical Standardization (CENELEC). It is identical with IEC 1168:1993 Radiotherapy simulators Functional performance characteristics, published by the International Electrotechnical Commission (IEC). It is simultaneously published as BS 5724 Medical electrical equipment Section 3.129:1994 Methods of d
11、eclaring functional performance characteristics of radiotherapy simulators. This Particular Standard thus forms part of the group of standards directed specifically at electrical equipment used in health care. This Particular Standard details procedures by which the functional performance characteri
12、stics of radiotherapy simulators which use diagnostic X-ray equipment may be determined and specified. Guidance in the application of this standard is given in BS 5724-3.129:Supplement 1, which is published simultaneously. Annex A to this Particular Standard is for information only. Attention is dra
13、wn to BS 5724-2.129 which specifies the particular requirements for the safety of radiotherapy simulators. Additional information. The following print types are used in this standard. Requirements, compliance with which can be tested, and definitions: in roman type. Explanations, advice and general
14、statements: in small roman type. Terms defined in clause 2 of BS 5724-1, in clause 2 of BS 5724-2.129, in 3.2 of this Particular Standard and in BS 6641: SMALL CAPITALS. For the purposes of this British Standard, any references to IEC page numbers in the text should be ignored. Textual errors. When
15、adopting the text of the International Standard, the textual errors listed below were discovered. They have been marked in the text and have been reported to IEC in a proposal to amend the text of the International Standard. In Table 9, after “ISOCENTRE” in the last column heading, should be inserte
16、d: “when the table top rotation is set to 0”. The sentence immediately after Table 9 should be replaced by the following: “Half the difference of the instrument readings is equal to the angle of tilt of the table top rotation axis (5) relative to the ISOCENTRIC rotation axis (6) in the direction of
17、the line joining these two axes. Half the sum of the instrument readings is equal to the angle of tilt of the table top rotation axis (5) in the direction perpendicular to the line joining axes (5) and (6).” A British Standard does not purport to include all the necessary provisions of a contract. U
18、sers of British Standards are responsible for their correct application. 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, the EN title page, pages 2 to 20, an i
19、nside 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 the inside front cover. Licensed Copy: sheffieldun sheffieldun, na, Wed Nov 08 02:24:34 GMT+00:00 2006, Uncontrolled Copy,
