It amends and supplements IEC 60601-1 (second edition, 1988), including its amendments 1 (1991) and 2 (1995) hereinafter referred to as the General Standard. The requirements of this Particular Standard take priority ove

36、r those of the General Standard, entitled Medical electrical equipment Part 1: General requirements for safety. 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 no

37、t only facilitate the proper application 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

38、or subclause number indicates that some explanatory notes are given in Annex AA.

39、E 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 Addition: This Particular Standard specifies requirements for the safety, including essential performance

40、, of RECORDING AND ANALYSING SINGLE CHANNEL AND MULTICHANNEL ELECTROCARDIOGRAPHS as defined in 2.101, 2.111, 2.117, 2.123, 2.126, hereinafter referred to as EQUIPMENT. The EQUIPMENT may be attended or unattended. This Particular Standard complements IEC 60601-2-25 and its Amendment 1 (1999). 1.2 Obj

41、ect Replacement: The object of this Particular Standard is to establish particular requirements, in addition to the requirements of IEC 60601-2-25, for the safety, including essential performance of RECORDING AND ANALYSING SINGLE CHANNEL AND MULTICHANNEL ELECTROCARDIOGRAPHS. These requirements shall

42、 apply particularly to RECORDING ELECTROCARDIOGRAPHS; ELECTROCARDIOGRAPHS which are part of other MEDICAL ELECTRICAL EQUIPMENT, for example exercise testing systems, if this EQUIPMENT is used to record ECGs for diagnostic purposes; ELECTROCARDIOGRAPHS which are used as output units for ECG data base

43、 management systems or ELECTROCARDIOGRAPHS which are used as output units located at other places than the recording unit; ANALYSING ELECTROCARDIOGRAPHS, systems, and computing devices which by means of electronic data processing and pattern recognition derive measurements (e.g. intervals and amplit

44、udes) and diagnostic statements from the ECG; those parts of PATIENT monitors or other specialised ELECTROCARDIOGRAPHS that are capable of performing the functions of the ANALYSING ELECTROCARDIOGRAPHS. This standard shall not apply to Holter ELECTROCARDIOGRAPHS, invasive electrocardiography, PATIENT

45、 monitoring systems and high-resolution ELECTROCARDIOGRAPHS (e.g. HIS bundle ELECTROCARDIOGRAPHS, ELECTROCARDIOGRAPHS for late potential detection) other than stated above. Page6 EN60601251:2003 1.3 Particular Standards Addition: This Particular Standard refers to IEC 60601-1:1988, Medical electrica

46、l equipment Part 1: General requirements for safety, as amended by its Amendment 1 (1991) and Amendment 2 (1995), hereafter referred to as the General Standard, and to IEC 60601-2-25:1993, Medical electrical equipment Part 2-25: Particular requirements for the safety of electrocardiographs and its A

47、mendment 1 (1999). The General Standard also takes into account IEC 60601-1-2:1993, Medical electrical equipment Part 1: General requirements for safety 2. Collateral Standard: Electromagnetic compatibility Requirements and tests, and IEC 60601-1-4:1996, Medical electrical equipment Part 1: General
