ASTM D5556-95(2011)

Standard Test Method for Determination of the Moisture and Other Volatile Matter Contained in Fats and Oils Used in Fat Liquors and Softening Compounds

SIGNIFICANCE AND USE
This test method is intended for use in the determination of the moisture and other volatile matter contained in fats and oils used in the softening and stuffing of leather, as well as those used in the manufacture of products for such purpose.
SCOPE
1.1 This test method covers the determination of moisture and other volatile material under conditions of the test. It is applicable to all fats and oils, including emulsions.
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 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.
