ASTM E539-19 - 1.3.2019
 
Significance and Use

5.1 This method is suitable for providing data on the chemical composition of titanium alloys having compositions within the scope of the standard. It is intended for routine production control and for determination of chemical composition for the purpose of certifying material specification compliance. Additionally, the analytical performance data included with this method may be used as a benchmark to determine if similar X-ray spectrometers provide equivalent precision and accuracy.

5.2 Compositions outside the ranges in 1.1 may be reported if proper method validation is performed. Refer to Guide E2857 for information on method validation.
