INTERNATIONAL ELECTROTECHNICAL COMMISSION
MEDICAL ELECTRICAL EQUIPMENT
Part 2: Particular requirements for the safety of
nerve and muscle stimulators
FOREWORD

1) The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all

the National Committees having a special interest therein are represented, express, as nearly as possible, an international

consensus of opinion on the subjects dealt with.

2) They have the form of recommendations for inte rnational use and they are accepted by the National Committees in that

sense.

In order to promote international unification, the IEC expresses the wish that all National Committees should adopt the

text of the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence

between the IEC recommendation and the corresponding national rules should, as far as possible, be clearly indicated

in the latter.
PREFACE

This Particular Standard has been prepared by Sub-Committee 62D: Electromedical equipment, of IEC Technical

Committee No. 62: Electrical equipment in medical practice.
The text of this standard is based upon the following documents:
Six Months' Rule Report on Voting
62D(CO)29 62D(CO)32

Further information can be found in the Report on Voting indicated in the table above.

This Particular Standard amends and supplements IEC Publication 601-1 (first edition 1977): Safety of medical electrical

equipment, Part 1: General Requirements, hereinafter referred to as the General Standard. The requirements of this

Particular Standard take priority over those of the General Standard. The title of the General Standard will be changed in

the next edition to read: Medical electrical equipment, Part 1: General requirements for safety. This change is anticipated

in the title of this Particular Standard.

The numbering of sections, clauses and sub-clauses of this Particular Standard corresponds with that of the General

Standard.

Sub-clauses or 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), 6b), etc.
In this standard, the following print types are used:

requirements, compliance 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 requirements are followed by specifications for the relevant tests.

Following the decision taken by Sub-Committee 62D at the meeting in Washington in 1979, 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 will, in due course, expedite any revision necessitated by changes in clinical practice or as a result

of the requirements of this standard.
of developments in technology. However, this appendix does not form pa rt
