23、UIREMENTS FOR ELECTRICAL EQUIPMENT FOR MEASUREMENT, CONTROL, AND LABORATORY USE Part 2-061: Particular requirements for laboratory atomic spectrometers with thermal atomization and ionization FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardizat

24、ion comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes Internatio

25、nal Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in t

26、his preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the tw

27、o organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have th

28、e form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinter

29、pretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national

30、or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carri

31、ed out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Comm

32、ittees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn t

33、o the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be

34、held responsible for identifying any or all such patent rights. International Standard IEC 61010-2-061 has been prepared by IEC technical committee 66: Safety of measuring, control and laboratory equipment. It has the status of a group safety publication in accordance with IEC Guide 104. This third

35、edition cancels and replaces the second edition published in 2003. It constitutes a technical revision and includes the following change from the second edition: exclusion of equipment, whose size and weight make unintentional movement unlikely, from the drop test in Clause 8. notes have been re-phr

36、ased according to ISO/IEC Directives. BS EN 61010-2-061:2015 4 IEC 61010-2-061:2015 IEC 2015 The text of this standard is based on the following documents: FDIS Report on voting 66/553/FDIS 66/568/RVD Full information on the voting for the approval of this standard can be found in the report on voti

37、ng indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61010 series, under the general title: Safety requirements for electrical equipment for measurement, control, and laboratory use, may be found on the I

38、EC website. This Part 2-061 is intended to be used in conjunction with IEC 61010-1. It was established on the basis of the third edition (2010). This Part 2-061 supplements or modifies the corresponding clauses in IEC 61010-1 so as to convert that publication into the IEC standard: Safety requiremen

39、ts for laboratory atomic spectrometers with thermal atomization and ionization. Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. Where this part states “addition”, “modification” or “replacement”, or “deletion”, the relevant requ

40、irement, test specification or note in Part 1 should be adapted accordingly. In this standard: 1) the following print types are used: requirements: in roman type; NOTES: in small roman type; conformity and test: in italic type; terms used throughout this standard which have been defined in clause 3:

41、 SMALL ROMAN CAPITALS; 2) subclauses, figures, tables and notes which are additional to those in Part 1 are numbered starting from 101. The additional annexes are lettered starting from AA. The committee has decided that the contents of this publication will remain unchanged until the stability date

42、 indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. BS EN 61010-2-061:2015IEC 61010-2-061:2015 IEC 2015 5 SAFETY REQUIREMENTS FOR ELECTRI
