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.
