AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verificat

14、ion by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected int

15、erests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their exis

16、tence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no cir

17、cumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the sec

The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw t

23、g the use of IEC 60974-5 in the U.S. As such, any reference in this standard to an IEC 60974 part is understood to mean a reference to the equivalent ANSI/IEC 60974 part, where it exists. This standard contains all the original text as-is from IEC 60974-5, edition 2, in addition to a number of U.S.

24、Differences to the IEC standard that were identified by Accredited Standards Committee W1, Requirements for Apparatus Designed for Use in Arc Welding, Plasma Arc Cutting, and Allied Processes. Each U.S. Difference is found both in a compilation of U.S. Differences following this foreword, and insert

25、ed in the appropriate place(s) in the standard relating to the difference. Each insertion is in red text and is marked on its left by three lines (two thin, one thick). Each U.S. Difference is identified with the following format: Clause/Subclause NumberDV.Number of Difference for the Given Clause/S

26、ubclause Following this format, the example 17.1DV.3 signifies that it is the third U.S. Difference to subclause 17.1.

32、EC 60974“ ForewordDV.1 Modify the foreword by adding the following: The numbering system in this standard uses a space instead of a comma to indicate thousands and uses a comma instead of a period to indicate a decimal point. For example, 1 000 means 1,000 and 1,01 means 1.01. 2DV.1 Modify clause 2

34、ard to IEC 60974-1 shall be a reference to ANSI/IEC 60974-1. NOTE ANSI/IEC 60974-1-2008 contains the entire original text from IEC 60974-1:2005 plus U.S. Differences. 2DV.3 Modify clause 2 by replacing the reference to IEC 60974-7 with a reference to ANSI/IEC 60974-7 and adding the following text at

35、 the end of the clause: All subsequent references in this standard to IEC 60974-7 shall be a reference to ANSI/IEC 60974-7. NOTE ANSI/IEC 60974-7-2009 contains the entire original text from IEC 60974-7:2005 plus U.S. Differences. 2DV.4 Modify clause 2 by deleting the normative reference to IEC 60974

44、n (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 questions concerning standardization in the electrical and electronic fields. To this end and in ad

45、dition to other activities, IEC publishes International 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 inter

46、ested 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 collaborates closely with the International Organization for Standardization (ISO) in accordance wit

47、h 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 the relevant subjects since each technical committee has representation from all interested I

48、EC 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 that the technical content of IEC Publications is accurate, IEC cannot be held responsible for

49、 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 the 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to
