1.1These 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

1.2The 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

1.3Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This 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.

1.5This 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.
