1、Designation: D 2634 07Standard Specification forMethyl Amyl Acetate (95 % Grade)1This standard is issued under the fixed designation D 2634; 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 par

2、entheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers methyl amyl acetate2(95 %grade) for use in paint, varnish, and related products.1.2 The values stated in SI units are to

3、 be regarded asstandard. No other units of measurement are included in thisstandard.1.3 For specific hazard information and guidance, see thesuppliers Material Safety Data Sheet for materials listed in thisspecification.1.4 The following applies to all specified limits in thisstandard; for purposes
