详细信息   
文摘

These test methods are primarily intended to test refined nickel metal for compliance with compositional specifications. 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 the analytical work will be performed in a properly equipped laboratory under appropriate quality control practices.

1.1 These test methods apply to the chemical analysis of refined nickel and other forms of metallic nickel having chemical compositions within the following limits:

ElementWeight %
Antimony, less than0.005
Arsenic, less than0.005
Bismuth, less than0.01
Cadmium, less than0.0025
Carbon, max0.03
Cobalt, max1.00
Copper, max1.00
Hydrogen, max0.003
Iron, max0.15
Lead, less than0.01
Manganese, less than0.20
Nickel, min98.0
Nitrogen, less than0.50
Oxygen, less than0.03
Phosphorus, less than0.005
Selenium, less than0.0010
Silicon, less than0.005
Silver, less than0.01
Sulfur, max0.01
Tellurium, less than0.0010
Thallium, less than0.0010
Tin, less than0.005
Zinc, less than0.015

1.2 These test methods may be used to determine the following elements by the methods indicated below:

Antimony, Arsenic, Bismuth, Cadmium, Lead, Selenium, Silver, Tellurium, Tin, and Thallium by the Electrothermal Atomic Absorption Method
Bismuth, Cadmium, Cobalt, Copper, Iron, Lead, Manganese, Silver, and Zinc by the Flame Atomic Absorption Method
Carbon, Total, by the Combustion-Instrumental Method
Nickel by the Dimethylglyoxime Gravimetric Method
Nitrogen by the Inert Gas Fusion Thermal Conductivity Method
Oxygen by the Inert Gas Fusion Method
Sulfur by the Infrared Absorption Method
Sulfur by the Methylene Blue Spectrophotometric Method After Generation of Hydrogen Sulfide

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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. For specific precautions, see Section 6.
