3.1 This test method is used to measure the specific gravity of all oils and liquid fats that are used to soften leather, or that are used in products to soften leather. The specific gravity is one parameter that can be used to monitor the quality of these products.

1.1 This test method covers the determination of the specific gravity of oils and liquid fats by calculating the ratio of the weight of a unit volume of the sample to the weight of a unit volume of water at 25°C.

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.

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.
