Description

This Standard specifies a flame atomic absorption spectrometric method for the determination of lead content between 0.01% and 10% in copper alloys containing a maximum of 10% aluminium, 80% copper, 5% iron, 5% manganese, 40% nickel, 3% silicon, 10% tin and 40% zinc.

Scope

This Standard sets out the flame atomic absorption spectrometric method for the determination of lead in copper alloys. It is applicable to the range of 0.01% to 10% lead. The method has been found satisfactory in the presence of the following elements up to the concentrations indicated:

• Aluminium     10%
• Copper            80%
• Iron                  5%
• Manganese     5%
• Nickel               40%
• Silicon              3%
• Tin                   10%
• Zinc                 40%
