Significance and Use
4.1 This test method provides a measurement of inhibitor level in vinyl acetate. The results of these measurements can be used for specification acceptance.
1.1 This test method covers the determination of hydroquinone in the range from 1 to 20 ppm in refined, commercially available, vinyl acetate.
1.2 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 Practice E29.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
