ASTM D1617-90(2001)

Standard Test Method for Ester Value of Solvents and Thinners

SCOPE
1.1 This test method covers the determination of the ester value of solvents and thinners used in lacquers and other coatings.  
1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Note 2.
1.3 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
