ASTM D2800-92(1998)

Отменен
Standard Test Method for Preparation of Methyl Esters From Oils for Determination of Fatty Acid Composition by Gas-Liquid Chromatography (Withdrawn 2007) — 2 стр.
Причина отмены

This test method covers a rapid procedure for conversion of animal and vegetable fatty oils into methyl esters of the fatty acids suitable for analysis by gas-liquid chromatography.

Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in March 2007 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the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.

Область применения

1.1 This test method covers a rapid procedure for conversion of animal and vegetable fatty oils into methyl esters of the fatty acids suitable for analysis by gas-liquid chromatography.

1.2 This test method is believed to be applicable to most drying oils used in the paint industry including linseed, soya, safflower, and cottonseed oils. Unsaturated oils with a tendency to undergo alkaline isomerization or to polymerize in the presence of boron trifluoride (BF3) may give erroneous results. Unsaponifiables are not removed.

1.3 This standard does not purport to address all of the safety problems, 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. For specific hazard statements, see 5.4 and Note 1.
