This European Standard exists in three official versions(English, French, German ). A version in any other language made by translation under the responsibility of a CEnelec member into its own language and notified to the central secretariat has the same status as the official versions CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway Portugal, Spain, Sweden, Switzerland and United Kingdom CENELEC European Committee for Electrotechnical Standardization Comite Europeen de normalisation Electrotechnique Europaisches Komitee

was submitted to the lEC-CENELEC parallel vote and was approved by cenelec as en 61010-1 on 2001-01-01 This European standard supersedes en 61010-1: 1993 and its amendment A2: 1995 However, EN 61010-1: 1993, with its amendment A2: 1995, remains current for any part 2 first edition standard which has not been superseded by a part 2 second edition standard and which refers to EN61010-1:1993 The following dates were fixed latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop)201-1101 latest date by which the national standards conflicting with the en have to be withdrawn (dow)2004-01-01 Annexes designated"normative"are part of the body of the standard In this standard annexes a to h and za are normative Annex Za has been added by cenelec In this standard, the following print types are used requirements and definitions: in roman type NOTES: in smaller roman typ conformity: in italic type terms used throughout this standard which have been defined in clause 3: SMALL ROMAN CAPITALS Endorsement notice The text of the International Standard IEC 61010-1: 2001 was approved by CENELEc as a
