- Scope
- 1.1 This test method covers the determination by gas chromatography of propylene glycol monomethyl ether (PM), dipropylene glycol monomethyl ether (DPM), and propylene glycol monomethyl ether acetate (PMA). Note 1???Propylene glycol monomethyl ether (PM) is a mixture of two isomers: 1-methoxy-2-propanol and 2-methoxy-1-propanol.
8199;Dipropylene glycol monomethyl ether (DPM) is a mixture of four isomers: 1-(2-methoxy-1-methylethoxy)-2-propanol is one of the major isomers.
8199;Propylene glycol monomethyl ether acetate (PMA) is a mixture of two isomers: 1-methoxy-2-acetoxypropane and 2-methoxy-1-acetoxypropane.1.1.1 This test method covers the determination of PM in the range from 98 to 1008201;%, and DPM in the range from 0.08 to 0.68201;%.
1.2 Water and acid cannot be determined by this test method and must be measured in accordance with Test Methods D1364 and D1613, and the results used to normalize the chromatographic data.
1.3 The following applies to all specified limits in this standard; for purposes of determining conformance with this standard, an observed value or a calculated value 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.
1.6 This standard does not purport to address all of the safety concern......
