(Test Method)Standard Test Methods for Chemical Analysis of Manganese-Copper Alloys
Standard Test Methods for Chemical Analysis of Manganese-Copper Alloys
SIGNIFICANCE AND USE
These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
SCOPE
1.1 These test methods cover the chemical analysis of manganese-copper alloys having chemical compositions within the following limits:
1.2 The test methods appear in the following order:
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
11.1 This test method covers the determination of iron in concentrations from 0.003 % to 0.02 %.
21.1 This test method covers the determination of manganese in concentrations from 28.0 % to 32.0 %.
28.1 This test method covers the determination of phosphorus in concentrations from 0.002 % to 0.014 %.
