ASTM D3897
1. Scope
1.1 This practice is intended to show how the results of the chromium analysis (Test Method D 3898) and the acidity determination (Test Method D 3913) can be combined to permit calculation of the basicity of a chrome tanning liquor.
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.
