Summary

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 Spectrometry 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

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary information is given in Section 6, , , and .

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Significance and Use:

4.1 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.
