ASTM D1617-22

Standard Test Method for Ester Value of Solvents and Thinners

SIGNIFICANCE AND USE
4.1 This test method is useful in determining the assay of solvents and thinners which are esters or solutions of esters of carboxylic acid. The ester value is calculated as percent ester. This test method has its greatest application where the solvent or thinner is not a pure ester. This test method may be used in assessing compliance to specification.
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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.  
1.4 For hazard information and guidance, see the supplier’s Material Safety Data Sheet.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see 8.6.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
