Standard Test Method for Chromic Oxide in Ashed Wet Blue (Perchloric Acid Oxidation)

Importancia y uso:

5.1 The procedure described is specific for chromium in Wet Blue. Vanadium is the only common interfering element and this is rarely present in quantity. The precision and accuracy of the methods are usually at least as good as the sampling of the Wet Blue itself, and the accuracy of previously performed test methods.

5.2 The chromium content of Wet Blue is related to the degree of tannage obtained, and hence may be a matter for specification in the purchase of Wet Blue. The procedure described provides adequate accuracy for this purpose.
