1. Scope
1.1 These test methods cover the chemical analysis of manganese-copper alloys having chemical compositions within the following limits:
Element Concentration 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 max1.2 The test methods appear in the following order:
Sections Iron by the 1,10-Phenanthroline Photo- metric Method 8 to 17 Manganese by the (Ethylenedinitrilo) Tet- raacetic Acid (EDTA--Back-Titrimet- ric Method 18 to 24 Phosphorus by the Molybdivanadophos- phoric Acid Extraction Photometric Method 25 to 351.3 This standard does not purport to address all of the safety problems, 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. For precaution to be observed in the use of certain reagents, refer to Practices E50. A specific precautionary statement is given in Note 2.
