Standard Details

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

Element	Concentration, 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 Photometric Method [0.0002 to 0.0010%]	62-72
Arsenic by the Molybdenum Blue Photometric Method [0.001 to 0.005%]	40-50
Copper by the Neocuproine Photometric 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 Photometric Method [0.001 to 0.05%]	20-29
Thallium by the Rhodamine B Photometric Method [0.0003 to 0.005%]	30-39
Tin by the 8-Quinolinol Photometric Method [0.0025 to 0.0150%]	73-82
