ASTM E396 : 12e1

Standard Test Methods for Chemical Analysis of Cadmium

Standard Details

1.1 These test methods cover the chemical analysis of cadmium having chemical compositions with the following limits:

Element	Composition, max, %

Antimony	0.001
Arsenic	0.003
Copper	0.015
Lead	0.025
Silver	0.010
Thallium	0.003
Tin	0.010
Zinc	0.035

1.2 The test methods appear in the following order:

	Sections
Antimony by the Rhodamine B Spectrophotometric Method [0.0002 % to 0.0010 %]	62-72
Arsenic by the Molybdenum Blue Spectrophotometric Method [0.001 % to 0.005 %]	40-50
Copper by the Neocuproine Spectrophotometric Method [0.002 % to 0.030 %]	10-19
Copper, Lead, Silver, and Zinc by the Atomic Absorption Method [0.004 % to 0.02 % Cu, 0.01 % to 0.05 % Pb, 0.004 % to 0.02 % Ag and 0.01 % to 0.05 % Zn]	51-61
Lead by the Dithizone Spectrophotometric Method [0.001 % to 0.05 %]	20-29
Thallium by the Rhodamine B Spectrophotometric Method [0.0003 % to 0.005%]	30-39
Tin by the 8-Quinolinol Spectrophotometric Method [0.0025 % to 0.0150 %]	73-82
