1.1 This test method 2 covers the X-ray fluorescence analysis of titanium alloys for the following elements in the ranges indicated: Element Range, % Aluminum 0.041 to 8.00 Chromium 0.013 to 4.00 Copper 0.015 to 0.60 Iron 0.023 to 2.00 Manganese 0.003 to 9.50 Molybdenum 0.005 to 4.00 Nickel 0.005 to 0.80 Niobium 0.004 to 7.50 Palladium 0.014 to 0.200 Ruthenium 0.019 to 0.050 Silicon 0.014 to 0.15 Tin 0.017 to 3.00 Vanadium 0.017 to 15.50 Yttrium 0.0011 to 0.0100 Zirconium 0.007 to 4.00 1.2 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 10 . 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== 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.
