Significance and Use

These test methods for the chemical analysis of cadmium are primarily intended to test such material for compliance with compositional specifications in Specification B440. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.

1. Scope

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

1.3 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. Specific precautionary information is given in Section 6 and 25.8.
