6、s documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus develop- ment process, approved by the American National Standards Institute, which brings to
7、gether volunteers representing varied viewpoints and interests to achieve the fi nal product. Volunteers are not necessarily members of the Institute and serve with- out compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus devel- opment proc
8、ess, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other dam- age, of any nature whatsoever, whether special,
9、indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document. The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressly disclaims any express or
10、 implied warranty, including any implied warranty of merchantability or fi tness for a specifi c purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards documents are supplied “ AS IS .” The existence of an IEEE Standard does not imply that there ar
11、e no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the a
12、rt and comments received from users of the standard. Every IEEE Standard is subjected to review at least every fi ve years for revi- sion or reaffi rmation. When a document is more than fi ve years old and has not been reaffi rmed, it is reasonable to conclude that its contents, although still of so
13、me value, do not wholly refl ect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. In publishing and making this document available, the IEEE is not suggesting or rendering professional or other services for, or on behalf
14、of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any other person or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a com- petent professional in determining the exercise of reasonable care in any g
15、iven circumstances. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specifi c applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. S
16、ince IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its soci- eties and Standards Coordinating Committees are not able to provide an i
17、nstant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affi liation with IEEE. Suggestions for changes in documents should
18、be in the form of a proposed change of text, together with appropriate supporting comments.

This standard has been
24、prepared in an effort to improve the reliability, effi ciency, and performance of severe duty totally enclosed fan-cooled ( TEFC) squirrel cage induction motors, 370 kW (500 hp) and below; and to promote uniform specifi cation of such motors in petroleum and chemical industry applications. This stan
25、- dard refl ects the thinking of representatives of the petroleum and chemical industry and their supplying motor manufacturers. It was prepared by the Motors Working Group of the Petroleum and Chemical Indus- try Committee (PCIC). At the time this standard was approved, the working group had the fo
