1.2 The test methods in this standard are contained in the sections indicated as follows:

SectionsAluminum, Total by the 8-Quinolinol Gravimetric Method (0.20 to7.00 %)62 to 69Chromium by the Atomic Absorption Method (0.018 to 1.00 %)100 to 109Chromium by the Peroxydisulfate Oxidation-Titration Method(0.10 to 33.00 %)110 to 118Cobalt by the Ion-Exchange-Potentiometric Titration Method (2 to75 %)34 to 41Cobalt by the Nitroso-R-Salt Photometric Method (0.10 to5.0 %)42 to 51Copper by Neocuproine Photometric Method (0.010 to 10.00 %)52 to 61Iron by the Silver Reduction Titrimetric Method (1.0 to 50.0 %)127 to 134Manganese by the Metaperiodate Photometric Method (0.05 to2.00 %)8 to 17Molybdenum by the Ion Exchange-8-Hydroxyquinoline Gravi-metric Method (1.5 to 30 %)119 to 126Molybdenum by the Photometric Method (0.01 to 1.50 %)88 to 99Nickel by the Dimethylglyoxime Gravimetric Method (0.1 to84.0 %)70 to 77Niobium by the Ion Exchange-Cupferron Gravimetric Method(0.5 to 6.0 %)135 to 142Silicon by the Gravimetric Method (0.05 to 5.00 %)27 to 33Sulfur by the Combustion-Iodate Titration Method (0.006 to0.1 %)18 to 26Tantalum by the Ion Exchange-Pyrogallol SpectrophotometricMethod (0.03 to 1.0%)143 to 151Tin by the Solvent Extraction-Atomic Absorption Method (0.002to 0.10 %)78 to 87

1.3 Methods for the determination of several elements not included in these test methods can be found in Test Methods E 30, E 76, and E 1019.

1.4 Some of the concentration ranges given in are too broad to be covered by a single method, and therefore, these test methods contain multiple methods for some elements. The user must select the proper test method by matching the information given in the scope and interference sections of each test method with the composition of the alloy to be analyzed.

1.5 The values stated in SI units are to be regarded as standard. In some cases, exceptions allowed in Practice E 380 are also used.

1.6 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7 and in special caution and warning paragraphs throughout these test methods.
