ASTM E 2594:2020

1.1 This test method describes the inductively coupled plasma atomic emission spectrometric analysis of nickel alloys, such as specified by Committee B02, and having chemical compositions within the following limits: Element Application Range (%) Aluminum 0.01-1.00 Boron 0.001-0.050 Calcium 0.001-0.05 Carbon 0.10-0.20 Chromium 0.01-33.0 Cobalt 0.10-20.0 Copper 0.01-3.00 Iron 0.01-50.0 Lead 0.001-0.01 Magnesium 0.0001-0.100 Manganese 0.01-3.0 Molybdenum 0.01-30.0 Niobium 0.01-6.0 Nickel 25.0-80.0 Nitrogen 0.001-0.20 Oxygen 0.0001-0.003 Phosphorous 0.001-0.030 Sulfur 0.0001-0.010 Silicon 0.01-1.50 Tantalum 0.005-0.10 Tin 0.001-0.020 Titanium 0.001-6.0 Tungsten 0.01-5.0 Vanadium 0.01-1.0 Zirconium 0.01-0.10 1.2 The following elements may be determined using this test method. The test method user should carefully evaluate the precision and bias statements of this test method to determine applicability of the test method for the intended use. Element Quantification Range (%) Aluminum 0.060-1.40 Boron 0.002-0.020 Calcium 0.001-0.003 Copper 0.010-0.52 Magnesium 0.001-0.10 Manganese 0.002-0.65 Niobium 0.020-5.5 Phosphorous 0.004-0.030 Tantalum 0.010-0.050 Tin 0.002-0.018 Titanium 0.020-3.1 Tungsten 0.007-0.11 Vanadium 0.010-0.50 Zirconium 0.002-0.10 1.3 This test method has only been interlaboratory tested for the elements and ranges specified. It may be possible to extend this test method to other elements or different quantification ranges provided that method validation is performed that includes evaluation of method sensitivity, precision, and bias as described in this document. Additionally, the validation study must evaluate the acceptability of sample preparation methodology using reference materials or spike recoveries, or both. The user is cautioned to carefully evaluate the validation data against the laboratory's data quality objectives. Method validation of scope extensions is also a requirement of ISO/IEC17025. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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 warning statements are given in 8.2.6.3 and safety hazard statements are given in Section 9 . 1.6 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.
