12、alth Care Standards Policy Committee and is identical with IEC Publication601-2-3 “Medical electrical equipment Part2: Particular requirements for the safety of short-wave therapy equipment”, published by the International Electrotechnical Commission (IEC). In1993 the European Committee for Electrot
13、echnical Standardization (CENELEC) accepted IEC601-2-3:1991 as European Standard EN60601-2-3:1993. As a consequence of implementing the European Standard, this BritishStandard is renumbered as BS EN60601-2-3 and any reference to BS5724-2.3 should be read as a reference to BS EN60601-2-3. This Part s
14、upersedes the1983 edition of BS5724-2.3 which is withdrawn. The main difference between this edition and the previous edition is that it is based on the1989 edition of the General Standard BS5724-1. Further differences are given in the introduction. This Particular Standard amends and supplements BS
15、5724-1, hereinafter referred to as the General Standard. As stated in clause 1.3 of the General Standard, the requirements of a Particular Standard take precedence over those of the General Standard. As in the General Standard the requirements are followed by compliance tests. The numbers of the sec
16、tions and clauses in this standard refer to the related sections and clauses in the General Standard. Clauses, subclauses or figures that are additional to those of the General Standard are numbered starting from101, the additional appendix is lettered AA, and additional items aa), bb), etc. The cha
17、nges from the text of the General Standard are specified by the use of the following words. “Replacement” means that the clause, subclause or specified paragraph of the General Standard is replaced by the text of this standard. “Amendment” means that the clause, subclause or specified paragraph of t
18、he General Standard is amended as indicated by the text of this standard. “Addition” means that the text of the standard is additional to the requirements of the General Standard The Technical Committee has reviewed the provisions of CISPR Publication11, to which reference is made in clause36 of the
19、 text, and has decided that they are acceptable for use in conjunction with this standard. NOTEIn BS5724-2.3:1983, the note to clause36 of IEC601-2-3 was replaced by a reference to Statutory Instrument S.I.1895/1963 which is applicable to short-wave therapy equipment. This S.I. is expected to be wit
20、hdrawn in1992 when it will be replaced by legislation arising from the Electromagnetic Compatibility Directive89/336/EEC.

When adopting the text of the International Standard, the textual errors listed below were discovered. They have been mar

In line7 of clause42, delete “Sub-clause50.2” and substitute “Clause50 of this Particular Standard”. In line3 o
23、f51.2 delete “Sub-clause50.2” and substitute “Clause50 of this Particular Standard”. 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 its
24、elf confer immunity from legal obligations.

39、 equipment. A first edition of this Particular Standard was published in1982, based on the first edition of the General Standard, IEC Publication601-1 (1977). The present second edition of the Particular Standard refers to the second edition (1988) of the General Standard. The revision of this secon
40、d edition concerns mainly the following: 1. Low power equipment (10W) is exempted from certain requirements as it is considered that no hazard exists. 2. Equipment with inductive applicators is dealt with in more detail. 3. Some shortcomings of the first edition detected in the application of the St
41、andard are removed. The requirements of this Particular Standard take priority over those of the General Standard. The title of the General Standard has been changed in the second edition (1988) to read: “Medical electrical equipment, Part1: General requirements for safety”. The change is reflected
42、in this Particular Standard. Where it is intended that any part of the General Standard, although possibly relevant, is not to be applied, a statement to that effect is given in this Particular Standard. The numbering of sections, clauses and sub-clauses of this Particular Standard corresponds with
43、that of the General Standard. Sub-clauses or figures which are additional to thoseof the General Standard are numbered starting from101; additional appendices are lettered AA, BB, etc., and additional items aa), bb), etc. In this Standard, the following print types are used: requirements, compliance
44、 with which can be tested, and definitions: in roman type; explanations, advice, introductions, general statements, exceptions and references: in smaller type; test specifications: in italic type; TERMS DEFINED IN CLAUSE 2 OF THE GENERAL STANDARD OR THIS PARTICULAR STANDARD: SMALL CAPITALS. The requ
45、irements are followed by specifications for the relevant tests. A rationale for the more important requirements, where appropriate, is given in Appendix AA. It is considered that a knowledge of the reasons for these requirements will not only facilitate the proper application of the standard but wil
46、l, in due course, expedite any revision necessitated by changes in clinical practice or as a result of developments in technology. However, this appendix does not form part of the requirements of this Standard. The sub-clauses which have corresponding rationale statements are marked with an asterisk
47、 (*) before their number. Section 1. General 1 Scope and object This clause of the General Standard applies except as follows: 1.1 Scope Addition: This particular Standard specifies the requirements for the safety of SHORT-WAVE THERAPY EQUIPMENT as defined in sub-clause 2.1.101 hereinafter referred
48、to as EQUIPMENT having a RATED OUTPUT POWER not exceeding500W. LOW POWER EQUIPMENT as defined in subclause2.2.101 is exempted from certain requirements of this standard. 1.5 Collateral Standards Addition: The following Collateral Standards apply: IEC60601-1-1:1992, Medical electrical equipment Part1
