Scope of standard 1.1 This test method covers the analysis of cast iron by spark atomic emission spectrometry for the following elements in the ranges shown (Note 1): Ranges, % Elements Applicable Range, % Quantitative Range, %A Carbon 1.9 to 3.8 1.90 to 3.8 Chromium 0 to 2.0 0.025 to 2.0 Copper 0 to 0.75 0.015 to 0.75 Manganese 0 to 1.8 0.03 to 1.8 Molybdenum 0 to 1.2 0.01 to 1.2 Nickel 0 to 2.0 0.02 to 2.0 Phosphorus 0 to 0.4 0.005 to 0.4 Silicon 0 to 2.5 0.15 to 2.5 Sulfur 0 to 0.08 0.01 to 0.08 Tin 0 to 0.14 0.004 to 0.14 Titanium 0 to 0.12 0.003 to 0.12 Vanadium 0 to 0.22 0.008 to 0.22(A) Quantitative range as directed in Practice E1601. Note 1: The ranges of the elements listed have been established through cooperative testing of reference materials. These ranges can be extended by the use of suitable reference materials. 1.2 This test method covers analysis of specimens having a diameter adequate to overlap the bore of the spark stand opening (to effect an argon seal). The specimen thickness should be sufficient to prevent overheating during excitation. A heat sink backing may be used. The maximum thickness is limited only by the height that the stand will permit. 1.3 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. 1.4 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.
