ASTM E106-83(2004) - 1.6.2004
 
Significance and Use

These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials 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 work will be performed in a properly equipped laboratory.

 
1. Scope

1.1 These test methods cover procedures for the chemical analysis of copper-beryllium alloys having chemical compositions within the following limits: ElementConcentrationRange,%Copper97 to 98Beryllium0.4 to 2.05Nickel0.0 to 0.30Cobalt0.0 to 0.3Iron0.0 to 0.30

1.2 The analytical procedures appear in the following order:

SectionsCopper by the Electrolytic MethodBeryllium:Phosphate Gravimetric MethodAluminon (Photometric) MethodNickel by the Dimethylglyoxime (Photometric) MethodCobalt by the Nitroso-R-Salt (Photometric) MethodIron by the Thiocyanate (Photometric) Method

1.3 This test method covers the determination of beryllium in concentrations from 0.1 to 3.0 %.
