This test method2 covers the analysis of austenitic
stainless steel by spark atomic emission vacuum spectrometry for
the following elements in the ranges shown
This test method is designed for the routine analysis of
chill-cast disks or inspection testing of stainless steel samples
that have a flat surface of at least 13 mm (0.5 in.) in diameter.
The samples must be sufficiently massive to prevent overheating
during the discharge and of a similar metallurgical condition and
composition as the reference materials.
One or more of the reference materials must closely approximate
the composition of the specimen. The technique of analyzing
reference materials with unknowns and performing the indicated
mathematical corrections may also be used to correct for
interference effects and to compensate for errors resulting from
instrument drift. A variety of such systems are commonly used. Any
of these that will achieve analytical accuracy equivalent to that
reported for this test method are acceptable.
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.
