Standard Test Method for Analysis of Cast Iron by Spark Atomic Emission Spectrometry
 N E1999

Annotation

This test method covers the analysis of cast iron by spark atomic emission spectrometry for the following elements in the concentration ranges shown (Note 1):

NOTE 1—The concentration ranges of the elements listed have been established through cooperative testing of reference materials. These concentration ranges can be extended by the use of suitable reference materials.

This test method covers analysis of specimens having a diameter adequate to overlap the bore of the spark stand opening (to effect an argon seal). The specimen thickness should be sufficient to prevent overheating during excitation. A heat sink backing may be used. The maximum thickness is limited only by the height that the stand will permit.

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.
