1.1This test method provides for the analysis of high manganese steel by spark atomic emission spectrometry for the following elements in the ranges shown:

Elements	Conposition Range, %

Aluminum (Al)	0.02 to 0.15
Carbon (C)	0.3 to 1.4
Chromium (Cr)	0.25 to 2.00
Manganese (Mn)	8.0 to 16.2
Molybdenum (Mo)	0.03 to 2.0
Nickel (Ni)	0.05 to 4.0
Phosphorus (P)	0.025 to 0.06
Silicon (Si)	0.25 to 1.5

Note 1-The ranges represent the actual levels at which this method was tested.² These composition ranges can be extended to higher compositions by the use of suitable reference materials. Sulfur is not included because differences in results between laboratories exceeded acceptable limits at all analyte levels.

1.2This test method may involve hazardous materials, operations, and equipment. 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.
