Historical Version s – view previous versions of standard. Electrode and argon are described in 7.
Make the necessary corrections either by adjusting the controls on the readout or by applying arithmetic corrections. There shall be at least three calibrants for each element, spanning the required concentration range.
Flush, s Asm, s Exposure, s 2 10 10 or 15 Argon Flow 0. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. A variety of such systems are commonly used. The technique of analyzing reference materials along with unknowns and performing the indicated mathematical e106 may also be used to correct for interference effects and to compensate for errors resulting from instrument drift.
This procedure is suitable for manufacturing control and inspection testing. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Link to Active This link will always route to xstm current Active version of the standard.
Refer to Practice E For example, a disk-shaped specimen should have a ring of excitation marks around its outer edge and approximately 6 mm 0. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials.
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.
The discharge is terminated at a predetermined level of accumulated radiant energy from the internal standard iron line or after a? The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials.
The wall thickness of the mold should be 32 mm 1. Excitation and Exposure Last previous edition approved in as E — 94 Prepare the surface of the specimens and reference materials in a similar manner.

B Either iron line A number xstm parentheses indicates the year of last reapproval. If wet surfacing procedure is used, dry the specimens asstm proper excitation in the argon atmosphere. These reference materials shall be homogeneous, and free of voids or porosity.
Grinding materials with grit sizes ranging from 60 to have been found satisfactory. Procedure for Excitation and Radiation Measurement Examine the specimen after each excitation to evaluate the quality of excitation. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

This procedure is suitable for manufacturing control and inspection testing. Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. Equipment varies among laboratories.
One or more of the reference materials must closely approximate the composition of the specimen.
Calibration, Standardization, and Veri? The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition asstm the reference materials.
