Standard Test Method for Purity of Methyl Ethyl Ketone By Gas Chromatography
N D2804
Annotation
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.
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 E29.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
For hazard information and guidance, see the supplier's Material Safety Data Sheet.
*A Summary of Changes section appears at the end of this standard
