(Test Method)Standard Test Method for Purity of Methyl Ethyl Ketone By Gas Chromatography
Standard Test Method for Purity of Methyl Ethyl Ketone By Gas Chromatography
SCOPE
1.1 This test method covers the determination of the purity of methyl ethyl ketone by gas chromatography. Impurities including water, acidity, and nonvolatile matter are measured by appropriate ASTM procedures and the results are used to normalize the chromatographic value.
1.2 For purposes of determining conformance of an observed value 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.
1.3 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
