Standard Test Methods for Analysis of Methanol (Withdrawn 2017)
SIGNIFICANCE AND USE
3.1 These test methods are suitable for manufacturing control and for determining compliance with specification limits for the properties designated by the test methods. For those test methods that use the procedure given in other ASTM methods, those test methods should be consulted for additional information on the significance, use, and possible interferences.
SCOPE

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 Review the current Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures and safety precautions for the chemicals used in this standard.
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. Specific hazards statements are given in Sections 5 and 15 and in 16.1, 16.4, and 52.2.2.
WITHDRAWN RATIONALE
These test methods cover chemical and physical tests for measuring the quality of methanol.
Formerly under the jurisdiction of Committee D16 on Aromatic, Industrial, Specialty and Related Chemicals, this test method was withdrawn in March 2017 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
