13、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 interests. Substantial agreement means much more than a simple majority, but not necessa
14、rily 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 existence does not in any respect preclude anyone, whether he has approved the standards
15、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 circumstances give an interpretation of any American National Standard. Moreover, no per
16、son 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 secretariat or sponsor whose name appears on the title page of this standard. Caution No
17、tice: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard.

21、 first edition of this standard was essentially based on the EEI-NEMA Standard Wet-Process Porcelain Insulators (Apparatus, Cap and Pin Type), EEI TDJ-58, NEMA 146-1956. (EEI is the Edison Electric Institute; NEMA is the National Electrical Manufacturers Association). Subsequent revisions were devel
22、oped by the American National Standards Committee on Insulators for Electric Power Lines, C29. This standard has been revised four times by the C29 Committee. The principal differences between this revision and the 1980 edition include: 1) moving packing recommendations to the Appendix 2) changing t
23、he description of the test for ferrous metal parts galvanizing 3) replacing the figures with a table of dimensions and characteristics 4) requiring electrical tests to be made on completely assembled insulators This standard was processed and approved for submittal to ANSI by Accredited Standards Co
24、mmittee on Insulators for Electric Power Lines, C29. Committee approval of the standard does not necessarily imply that all committee members voted for approval.
