Standard Test Method for Chromic Oxide in Leather (Perchloric Acid Oxidation)

ASTM D2807-25

Organization:
ASTM - ASTM International
Year: 2025

Abstract: 4.1 The procedure described is specific for chromium in leather. The precision and accuracy of the methods are usually at least as good as the sampling of the leather itself. 4.2 The chromium content of leather relates to the degree of tannage obtained, and hence may be a matter for specification in the purchase of leather. The procedure described provides adequate accuracy for this purpose.

scope1.1 This test method covers the determination of chromic oxide in leathers that have been partly or completely tanned with chromium compounds. In general, the samples will contain between 1 % and 5 % chromium, calculated as chromic oxide. 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. See Section 8 for specific safety hazards. 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.
