Historical Standard: ASTM D6656-01 Standard Test Method for Determination of Chromic Oxide in Wet Blue (Perchloric Acid Oxidation)
SUPERSEDED (see Active link, below)
ASTM D6656
1. Scope
1.1 This test method covers the determination of chromic oxide in wet blue that has been partly or completely tanned with chromium compounds. In general, the samples will contain chromium content between 1 % and 5 % when calculated as chromic oxide expressed upon a dry basis otherwise referred to as moisture-free basis (mfb).
1.2 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. See Section for 9 specific safety hazards.
