ASTM D5346-17

Standard Test Method for Determination of the Pour Point of Petroleum Oil Used in Fatliquors and Softening Compounds

SIGNIFICANCE AND USE
3.1 This test method is intended to determine the pour point of petroleum oils used in the softening and stuffing of leather, as well as those used in the manufacture of products for such purpose. The pour point of petroleum oils is measured for the purpose of quality assurance.
SCOPE
1.1 This test method covers the determination of the pour point of petroleum oils used in the softening and stuffing of leather, and in the manufacture of fatliquors and other softening and stuffing compounds. This test method was derived from Test Method D97 and ALCA Method H-18.  
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, health and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
