It amends and supplements IEC 60601-1 (second edition 1988): Medical elecfrical equiprnenf - Parf 1: General requirernenfs for safefy, as amended by its amendment 1 (1991) and its amendment 2 (1995), hereinafter referred to as the General Standard. The requirement

    27、s of this Particular Standard take priority over those of the General Standard. A “General guidance and rationale” for the requirements of this Particular Standard is included in annex AA. It is considered that a knowledge of the reasons for these requirements will not only facilitate the proper app

    28、lication of the standard but will, in due course, expedite any revision necessitated by changes in clinical practice or as a result of developments in technology. However, this annex does not form part of the requirements of this Standard. An asterisk (*) by a clause or subclause number indicates th

    30、CTION ONE -GENERAL The clauses and subclauses of this section of the General Standard apply except as follows: 1 Scope and object This clause of the General Standard applies except as follows: 1.1 Scope Addifion: This Particular Standard specifies the particular safety requirements for AMBULATORY EL

    31、ECTROCARDIOGRAPHIC SYSTEMS, as defined in 2.1 01. Within the scope of this standard are systems of the following types: a) systems that provide continuous recording and continuous analysis of the ECG allowing full re-analysis giving essentially similar results. The systems may first record and store

    32、 the ECG and analyse it later on a separate unit, or record and analyse the ECG simultaneously. The type of storage media used is irrelevant with regard to this standard; b) systems that provide continuous analysis and only partial or limited recording not allowing a full re-analysis of the ECG. The

    33、 safety aspects of this standard apply to all types of systems falling in one of the above- mentioned categories. If the ambulatory electrocardiographic system offers automatic ECG analysis, minimal performance requirements for measurement and analysis functions apply. Medical electrical equipment c

    34、overed by IEC 60601-2-25 and IEC 60601-2-27 are excluded from the scope of this standard. This standard does not apply to systems that do not continuously record and analyse the ECG (for example, intermittent event recorders). 1.2 Object Replacemenf: The object of this Particular Standard is to esta

    36、 equipmenf - Parf 1: General requiremenfs for safefy, as amended by its amendment 1 (1991) and its amendment 2 (1 995). For brevity, IEC 60601-1 is referred to in this Particular Standard either as the General Standard including its collateral standards or as the General Requirement(s). The numberin

    37、g of sections and subclauses of this Particular Standard corresponds to that of the General Standard. Changes to the text of the General Standard are specified by the following words: Replacement means that the clause or subclause of the General Standard is replaced completely by the text of this Pa

    38、rticular Standard. Addition means that the text of this Particular Standard is additional to the requirements of the General Standard. Amendment means that the clause or subclause of the General Standard is amended as indicated by the text of this Particular Standard. Clauses, subclauses, tables and

    39、 figures which are additional to those of the General Standard are numbered starting from 101, additional appendices are lettered AA, BB, etc., and additional items aa), bb), etc. The term this Standard is used to make reference to the General Standard and this Particular Standard taken together. Wh

    40、ere there is no corresponding section, clause or subclause in this Particular Standard, the section, clause or subclause of the General Standard, although possibly not relevant, applies without modification; where it is intended that any part of the General Standard, although possibly relevant, is n
