21、OPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface (UL) This UL Standard is based on IEC Publication 61010-2-051: third edition, Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use Part 2-051: Particular
22、 Requirements for Laboratory Equipment for Mixing and Stirring. IEC publication 61010-2-051 is copyrighted by the IEC. Efforts have been made to synchronize the UL edition number with that of the corresponding IEC standard with which this standard is harmonized. As a result, one or more UL edition n
23、umbers have been skipped to match that of the IEC edition number. This UL Standard 61010-2-051 Standard for Safety for Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use Part 2-051: Particular Requirements for Laboratory Equipment for Mixing and Stirring, is to
24、be used in conjunction with the third edition of UL 61010-1. The requirements for laboratory equipment for the heating of materials are contained in this Part 2 Standard and UL 61010-2-051. Requirements of this Part 2 Standard, where stated, amend the requirements of UL 61010-1. Where a particular s
25、ubclause of UL 61010-1 is not mentioned in UL 61010-2-051, the UL 61010-1 subclause applies. The text, gures and tables of IEC Publication Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use Part 2-051: Particular Requirements for Laboratory Equipment for Mixing
26、and Stirring, IEC 61010-2-051, copyright March, 2015 are used in this Standard with the consent of the IEC and the American National Standards Institute (ANSI).

30、ION FROM UL INTERNATIONAL ELECTROTECHNICAL COMMISSION SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT FOR MEASUREMENT, CONTROL AND LABORATORY USE Part 2-051: Particular requirements for laboratory equipment for mixing and stirring FOREWORD 1) The International Electrotechnical Commission (IEC) is a wor
31、ldwide organization for standardization 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 elds. To this end and in addition to other ac
32、tivities, IEC publishes International Standards, Technical Specications, Technical Reports, Publicly Available Specications (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 d
33、ealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determine
34、d by agreement between the two 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
35、. 3) IEC Publications have the 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
36、 are used or for any misinterpretation 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 an
37、d the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certication bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not respons
38、ible for any services carried out by independent certication 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 committ
39、ees and IEC National Committees 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
40、. 8) Attention is drawn to 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
41、rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61010-2-051 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 I
42、EC Guide 104. JULY 31, 2015 UL 61010-2-051 (IEC 61010-2-051:2015) 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL This third edition cancels and replaces the second edition published in 2003. It constitutes a technical revision and includes
43、 the following signicant changes from the second edition, as well as numerous other changes: exclusion of equipment, whose size and weight make unintentional movement unlikely, from the drop test in Clause 8; added requirement for interlock systems containing electric/electronic or programmable comp
44、onents to Clause 15; notes have been re-phrased according to ISO/IEC Directives. The text of this standard is based on the following documents: FDIS Report on voting 66/552/FDIS 66/567/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated
45、 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 IEC website.
46、This Part 2-051 is intended to be used in conjunction with IEC 61010-1. It was established on the basis of the third edition (2010). This Part 2-051 supplements or modies the corresponding clauses in IEC 61010-1 so as to convert that publication into the IEC standard: Safety requirements for laborat
47、ory equipment for mixing and stirring. 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”, “modication”, “replacement”, or “deletion” the relevant requirement, test specication or note in Part 1 sh
48、ould 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 dened in Clause 3: SMALL ROMAN CAPITALS; 2) subclauses, gures, table
49、s and notes which are additional to those in Part 1 are numbered starting from 101. Additional annexes are lettered starting from AA. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under http:/webstore.iec.ch in the data related to the specic publication.
