Standard Test Method for Determination of Traces of Methanol in Propylene Concentrates by Gas Chromatography
N D4864
Annotation
This test method covers the determination of methanol in propylene concentrates in the range of approximately 4 mg ?kg to 40 mg/kg (parts-per-million by mass).
The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
NOTE 1—There is no direct acceptable SI equivalent for screw threads.
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. Specific warning statements are given in 11.1.1, 11.2.1, and 12.11.
*A Summary of Changes section appears at the end of this standard
