EUROPEAN STANDARD EN61010- NORME EUROPEENNE EUROPAISCHE NORM October 2010 cs19.080:71.040.10 Supersedes EN 61010-1: 2001+ corr Jun 2002 English version Safety requirements for electrical equipment for measurement, control, and laboratory use Part 1: General requirements (EC61010-1:2010) Regles de securite pour appareils Sicherheitsbestimmungen fur elektrische electriques de mesurage, de regulation et Mess-, Steuer-, Regel-und Laborgerate de laboratoire Teil 1: Allgemeine Anforderungen Partie 1: Exigences generales (EC61010-1:2010) (CE|61010-1:2010) This European Standard was approved by CENELEC on 2010-10-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration Up-to-date lists and bibliographical references concerning such national standards may be obtained application to the Central Secretariat or to any CENELEC member 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, Bulgaria, Croatia, Cyprus the Czech RepubliC, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia Spain, Sweden, Switzerland and the United Kingdom CENELEC European Committee for Electrotechnical Standardization Comite Europeen de Normalisation Electrotechnique Europaisches Komitee fur Elektrotechnische Normung Management Centre: Avenue Marnix 17, B-1000 Brussels C 2010 CENELEC- All rights of exploitation in any fom and by any means reserved worldwide for CENELEC members Ref.No.EN61010-1:2010E BSEN61010-1:2010 EN61010-1:2010 Foreword The text of document 66/414/FDIS, future edition 3 of IEC 61010-1, prepared by IEC TC 66, Safety of measuring, control and laboratory equipment, was submitted to the IEC-CENELEC parallel vote and was approved by cenelec as en 61010-1 on 2010-10-01 This European standard supersedes en 61010-1: 2001 This edition includes the following significant changes from EN 61010-1: 2001, as well as numerous other changes The scope of the standard has been expanded to include all locations where these products may be used, so that both professional and non-professional versions of these products are within the scope The requirements for testing and measuring circuits(in various subclauses and the entirety of Clause 16) have been removed and included in a particular standard EN 61010-2-030 Insulation requirements(6. 7)have been completely rewritten Specific requirements have been added for solid insulation and thin-film insulation Subclause 6.7 now contains only the insulation requirements for MAINS CIRCUITS of OVERVOLTAGE CATEGORY II up to 300V, and for secondary circuits The insulation requirements for all other circuits have been moved to a new annex K Additional requirements for protection against mechanical HAZARDS (Clause 7) have been included Surface temperature limits(Clause 10) have been modified to conform to the limits of EN 563 Radiation requirements(Clause 12)have been modified, and take into account a distinction between intended emission and unintended emission Requirements for reasonably foreseeable misuse and ergonomic aspects have been added (Clause 16 A new clause (Clause 17) has been added to deal with HAZARDS and environments not covered by the standard, along with a new informative annex(Annex J)dealing with RISK assessment. A new informative annex(Annex E) addresses methods of reducing the POLLUTION DEGREE of a micro environment Requirements for the qualification of coatings for protection against PolluTIoN have been added (Annex H) A new informative annex(Annex I)has been added to further explain how to determine the WORKING oltaGE of a maINs circuit Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEc shall not be held responsible for identifying any or all such patent rights 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 2011-07-01 latest date by which the national standards conflicting with the en have to be withdrawn (dow)2013-10-01 BSEN61010-1:2010 EN61010-1:2010 Annex Za has been added by cenelec Endorsement notice The text of the International Standard IEC 61010-1: 2010 was approved by CENELEC as a European Standard without any modification In the official version, for Bibliography, the following notes have to be added for the standards indicated IEC 60079 series NOTE Harmonized in EN 60079 series( partially modified EC60085 NOtE Harmonized as en 6o085 Ec60112:1979 NOTE Harmonized as HD 214 S2: 1980(not modified) IEC 60127 series NoTE Harmonized in EN 60127 series(not modified) lEC 60204 series NOTE Harmonized in En 60204 series(partially modified) lEC 60332-1 series NOTE Harmonized in EN 60332-1 series(not modified) lEC 60332-2 series NOTE Harmonized in EN 60332-2 series(not modified lEC 60335 series NOTE Harmonized in EN 60335 series( partially modified) IEC 60364 series NOTE Harmonized in en 60364 series (partially modified ). lEC 60439 series NOTE Harmonized in EN 60439 series(partially modified). lEC 60439-1: 1999 NOTE Harmonized as En 60439-1: 1999(not modified EC60445:1999 NOTE Harmonized as en 60445: 2000(not modified) EC60447:1993 NOTE Harmonized as En 60447: 1993(not modified) lEC 60601 series NOTE Harmonized in EN 60601 series(partially modified EC60664-1 NOtE Harmonized as en 60664-1 Ec60695-10-2 NoTE Harmonized as en 60695-10-2 IEC 60950 series NOTE Harmonized in En 60950 series (partially modified).
