    1、Designation: D1676 03 (Reapproved 2011)Standard Test Methods forFilm-Insulated Magnet Wire1This standard is issued under the fixed designation D1676; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A numb

    2、er in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover procedures for testing film-insulated magnet wire that is used in electrical apparatus.Thesetest methods are inten

    3、ded primarily for the evaluation of theelectrical insulating materials used. The intent is that these testmethods be used, except where modified, by individual speci-fications for particular applications.1.2 These test methods present different procedures forevaluating given properties of round, rec
