Description of ASTM-D3545 2012ASTM D3545 - 06(2012)Standard Test Method for Alcohol Content and Purity of Acetate Esters by Gas ChromatographyActive Standard ASTM D3545 | Developed by Subcommittee: D01.35 Book of Standards Volume: 06.04 ASTM D3545Significance and Use 4.1 This test method is useful for identifying and for determining the quantity of various impurities in acetate esters. 4.2 Total purity of the acetate esters must be determined by use of other appropriate ASTM procedures with this test method. 1. Scope 1.1 This test method covers the determination by gas chromatography of the ester content and the corresponding alcohol content of acetate esters. This test method has been applied to ethyl, n -propyl, isopropyl, n -butyl, isobutyl, and 2-ethoxyethyl acetates. 1.2 Water, and in some cases acetic acid, cannot be determined by this test method and must be measured by other appropriate ASTM procedures and the results used to normalize the chromatographic value. 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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 For specific hazard information and guidance, see the supplier's Material Safety Data Sheet for material listed in this specification. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
