14、 standard is translated, only the English version published by IEEE should be considered the approved IEEE standard. Official statements A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual shall not be considered or inferred to be the
15、official position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be c

Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting informatio
17、n or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comment
18、s and questions also receive 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 instant response to comments or questions except in those cases where the matter has previously been address
19、ed. For the same reason, IEEE does not respond to interpretation requests.

If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on
32、the IEEE- SA Website at http:/ standards .ieee .or g/ about/ sasb/ patcom/ patents .html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that ar

This guide complements IEEE Std 344, Standard for Seismic Qualification of Equipment for Nuclear Power Gen
42、erating Stations by providing specific requirements and guidance for seismic qualification of metal- enclosed power switchgear assemblies. 1Changes include IEEE Std C37.81 include the following: a) Added definitions and guidance for Seismic Category I and Seismic Category II equipment. Seismic Categ
43、ory I equipment is equivalent to equipment defined as Class 1E in the previous revision. b) Added guidance on sites with high frequency content, including a fourth Generic Response Spectra (GRS). c) Added definitions for functional failure, structural damage and triaxial test d) Revised the definiti
44、ons for: 1) Biaxial test 2) Malfunction Metal-enclosed power switchgear assemblies fall into the category of complex devices as described in IEEE Std 344; therefore, basic seismic qualification is dependent upon test data. Analysis may be used in data reduction, reconciling response spectra, and eva
45、luating changes. A method of combined test and analysis may also be used in justifying seismic qualification of similar equipment to the tested samples. It should be noted that while the primary purpose of this guide is for the application of metal-enclosed power switchgear assemblies in nuclear power generating stations, it is not restricted to this application. This guide may also be used as a guide in other applications in which the seismic response of metal-enclosed power switchgear assemblies is a consideration. 1 Information on references can be found in Clause 2.
