Significance and Use

These test methods for the chemical analysis of beryllium metal are primarily intended as referee methods 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 the chemical analysis of beryllium having chemical compositions within the following limits:

	Concentration
Element	Range, %
Aluminum	0.05 to 0.30
Beryllium	97.5 to 100
Beryllium Oxide	0.3 to 3
Carbon	0.05 to 0.30
Copper	0.005 to 0.10
Chromium	0.005 to 0.10
Iron	0.05 to 0.30
Magnesium	0.02 to 0.15
Nickel	0.005 to 0.10
Silicon	0.02 to 0.15

1.2 The test methods in this standard are contained in the sections indicated below.

	Sections
Chromium by the Diphenylcarbazide Photometric Test Method [0.004 to 0.04 %]	10-19
Iron by the 1,10-Phenanthroline Photometric Test Method [0.05 to 0.25 %]	20-29
Manganese by the Periodate Photometric Test Method [0.08 to 0.04 %]	30-39
