The IEEE develops its standards through

7、a consensus develop-ment process, approved by the American National Standards Institute, which brings together volunteers representing variedviewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve with-out compensation. While the IEEE

8、administers the process and establishes rules to promote fairness in the consensus devel-opment process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information containedin its standards.Use of an IEEE Standard is wholly voluntary.

Furthermore, the viewpoint expressed at thetime a standard is approved an

12、d issued is subject to change brought about through developments in the state of the art andcomments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revi-sion or reaffirmation. When a document is more than five years old and has not been

13、reaffirmed, it is reasonable to concludethat its contents, although still of some value, do not wholly reflect the present state of the art.

When the need for interpretations is brought to the attention of IEEE,

16、the Institute will initiate action to prepareappropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that anyinterpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its soci-eties

17、 and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except inthose cases where the matter has previously received formal consideration. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership af

24、ation.)There is general agreement from experience that a number of service stresses influence the service life ofelectrical insulation in electric equipment. The purpose of IEEE Std 1-2000 is to provide guidance for thepreparation of thermal-aging test procedures to determine the temperature index (

25、TI) of electrical insulatingmaterials (EIM) and the thermal class of electrical insulation systems (EIS).The main changes from IEEE Std 1-1986 are as follows:a) The title was changed from a “Standard” to a “Recommended Practice” to be consistent with thepredominant verb used in the text, “should.”b)

26、 The table of thermal classification, now Table 3, was modified to include both numerical and letterdesignations and all currently recognized temperature classes.c) The multifactor testing portion of Clause 8 has been deleted because it is beyond the scope of thisrecommended practice, which covers t

27、emperature limits.This revision has been made with the intent of harmonization with IEC 60085-1984, Thermal evaluation andclassification of electrical insulation, and IEC 60505-1999, Evaluation and qualification of electrical insula-tion systems. This work was done by a working group of IEEE Standar

28、ds Coordinating Committee 4(SCC4), Insulation Systems. The members of the SCC4 working group are also technical experts of IEC TC98, Electrical Insulation Systems. TC 98 plans to draft a revision to IEC 60085-1984.At the time this revision was completed, the SCC4 working group had the following memb
