1、Designation: D2694 05 (Reapproved 2011)Standard Specification forDiethylene Glycol1, 2This standard is issued under the fixed designation D2694; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in

2、 parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers diethylene glycol for use in thepreparation of surface coatings.1.2 The following applies to all specified limits in
