Full Description

1.1 These test methods cover the chemical analysis of manganese-copper alloys having chemical compositions within the following limits:
Element Range, % Copper 68.0 to 72.0 Manganese 28.0 to 32.0 Carbon 0.03 max Iron 0.01 max Phosphorus 0.01 max Silicon 0.05 max Sulfur 0.01 max
1.2 The test methods appear in the following order:
  Sections 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 Units-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, health, and environmental 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.
