IEC publication 60730-2-6 is copyrighted by the IEC. This edition has been issued to
27、satisfy UL Standards policy or state other reason, including an administrative new edition, or out of necessity to incorporate extensive revisions. This UL Standard 60730-2-6, Standard for Automatic Electrical Controls Part 2-6: Particular Requirements for Automatic Electrical Pressure Sensing Contr
28、ols Including Mechanical Requirements, is to be used in conjunction with the fth edition of UL 60730-1. The requirements for electric actuators are contained in this Part 2 Standard and UL 60730-1. Requirements of this Part 2 Standard, where stated, amend the requirements of UL 60730-1. Where a part
29、icular subclause of UL 60730-1 is not mentioned in UL 60730-2-6, the UL 60730-1 subclause applies. These materials are subject to copyright claims of IEC and UL.

Note Although the intended primary application of this Standar
31、d is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. The previous version of UL 60730-2-6 included national differences to the following IEC requirements: 15.1.101, 18.102.2, 18.102.3,
32、 and H26.11. These national differences were deleted in this version of UL 60730-2-6.

The standard may not include all types of these National Differences. DR These are National Differences based on the national regulatory requirements.
35、 D1 These are National Differences which are based on basic safety principles and requirements, elimination of which would compromise safety for consumers and users of products. D2 These are national differences from IEC requirements based on existing safety practices. These requirements reect natio

Each national difference contains a description of what the national difference entails. Typically one of the following words is used to explain how the text of the national differenc

41、 controls including mechanical requirements FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
42、 questions concerning standardization in the electrical and electronic elds. To this end and in addition to other activities, IEC publishes International Standards, Technical Specications, Technical Reports, Publicly Available Specications (PAS) and Guides (hereafter referred to as “IEC Publication(
43、s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collab
44、orates closely with the International Organization for Standardization (ISO) in accordance with conditions determined 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
45、 the relevant subjects since each technical committee has representation from all interested IEC National Committees. 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
46、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 misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to th
47、e maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and 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 bod
48、ies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible 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 I
49、EC or its directors, employees, servants or agents including individual experts and members of its technical committees 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. 8) Attention is drawn to the Normative references cited in this
