【国外标准】 Standard Test Method for Acetone in Methanol (Withdrawn 2011)

This test method can be used to detect residual amounts of carbonyl compounds in synthetic and natural methanol. The carbonyl compounds are quantified by comparison to a known standard of acetone solution.Carbonyl compounds may be present as a result of contamination during storage, distribution, or manufacture. This test method may be used in assessing compliance with a specification.1.1 This test method covers a procedure for detecting the presence of acetone in methanol in amounts greater than 0.003 weight %.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 E 29.1.4 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.1.5 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
