Members of the committees serve voluntarily and
6、 without compensation. They are notnecessarily members of the Institute. The standards developed within IEEE represent a consensus of the broadexpertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interestin participating in the development
7、of the standard.Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no otherways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEEStandard. Furthermore, the viewpoint expressed at
8、 the time a standard is approved and issued is subject to changebrought about through developments in the state of the art and comments received from users of the standard. EveryIEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is morethan
9、five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of somevalue, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have thelatest edition of any IEEE Standard.Comments for revision of IEEE S
10、tandards are welcome from any interested party, regardless of membership affiliationwith IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together withappropriate supporting comments.Interpretations: Occasionally questions may arise regarding the meaning
11、 of portions of standards as they relate tospecific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiateaction to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it isimportant to ensure
12、 that any interpretation has also received the concurrence of a balance of interests. For this reason,IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instantresponse to interpretation requests except in those cases where the matter has previousl

18、ies of airswitches over a range of ambient temperatures. This is accomplished through a family of loadability factor curves.The Standards Committee on Power Switchgear, C37, which reviewed and approved this standard, had the followingpersonnel at the time of approval:E.
