ASTM D5348

This test method is intended to determine the moisture content of fats, oils, and fatliquors used in the softening and stuffing of leather. The moisture content is measured for the purpose of quality assurance.

1. Scope

1.1 This test method covers the determination of water existing in a sample of sulfonated or sulfated oil, or both, by distilling the sample with a volatile solvent. The test method is applicable only to sulfonated and sulfated oils that do not contain the following: mineral acids, free sulfonic acids, or free sulfuric acid esters; or alkali hydroxides, carbonates or acetates: or alcohol, glycerin, diethylene glycol, acetone, or other water-miscible volatile compounds. This test method was derived from Test Methods D500, Sections 4 through 9.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
