1.1 These test methods cover the chemical analysis of pig iron, gray cast iron (including alloy and austenitic), white cast iron, malleable cast iron, and ductile (nodular) iron having chemical compositions within the following limits:

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

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

1.4 Some of the concentration ranges given in are too broad to be covered by a single method and therefore this standard contains multiple methods for some elements. The user must select the proper method by matching the information given in the Scope and Interference sections of each 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.

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 hazards statements are given in Section and in special "Warning" paragraphs throughout these Methods.

1.6 This test method covers the determination of manganese in concentrations from 0.10 to 2.00 %.

1.7 This method covers the determination of phosphorus in concentrations from 0.02 to 0.90 %.
