1、Designation: D5638 05 (Reapproved 2010)An American National StandardStandard Test Method forChemical Resistance of Electrical Insulating Varnishes1This standard is issued under the fixed designation D5638; the number immediately following the designation indicates the year oforiginal adoption or, in

2、 the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the mechanical performance ofinsulating varnishes after exp

3、osure to various chemicals.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this
