Описание
Причина отменыThese 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under the jurisdiction of Committee D16 on Aromatic, Industrial, Specialty and Related Chemicals, this test method was withdrawn in March 2017 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the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.

Значение и использование

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.
