    Significance and Use

    4.1 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.

    1. Scope

    1.1 These test methods cover the chemical analysis of manganese-copper alloys having chemical compositions within the following limits:


    Range, %


    68.0 to 72.0


    28.0 to 32.0


    0.03 max


    0.01 max


    0.01 max


    0.05 max


    0.01 max

    1.2 The test methods appear in the following order:



    Iron by the 1,10-Phenanthroline
     Spectrophotometric Method
     [0.003 % to 0.02 %]

    11 – 20

    Manganese by the (Ethylenedinitrilo)
     Tetraacetic Acid (EDTA)—
     Back-Titrimetric Method [28 % to 32 %]

    21 – 27

    Phosphorus by the
     Molybdivanadophosphoric Acid
     Extraction Spectrophotometric Method
     [0.002 % to 0.014 %]

    28 – 38

    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.

    1.5 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.
