Link to Active This link will always route to the current Active version of the standard. Avoid the center of cast specimens because there is more chance of quench cracks and segregation.
Procedure for Excitation and Radiation Measurement Link to Active This link will always route to the current Active e106 of the standard. This procedure is suitable for manufacturing control and inspection testing. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxzstm service astm.
Successive excitations shall be sufficiently separated so that the discharge patterns do not overlap. Interference corrections will not be necessary if: Standardization will be done anytime veri?
ASTM E1086 – 14
It is the responsibility of the xstm of this standard to establish appropriate safety and health practices and determine the atm of regulatory limitations prior to use. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials. If the readout is not in direct concentration units, use this value to obtain the concentrations from the curves, or related scale values and concentration by reference to a table that has been previously prepared.
The agreement between the results obtained by chemical methods and those obtained by this test method is displayed in Table 3. Work Item s – proposed revisions of this standard. Calculation of Results Department of Commerce, Gaithersburg, MD ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
At the end of the exposure period, the charge on each capacitor is measured, and displayed or recorded as a relative energy or concentration. The stand shall provide an atmosphere of argon and may be water cooled. Spectral lines are listed in Table 1.

These may be either wet or dry grinding devices. Refer to Practice E Excitation and Exposure A superscript epsilon e indicates an editorial change since the last revision or reapproval. The following mold types have been found to produce acceptable samples.
Current edition approved Jan. 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.
Work Item s – proposed revisions of this standard. Active view current version of standard. The resulting surface should be uniformly plane and free of defects. Spectrometer characteristics for two of the instruments used in this test method are described as having dispersion of 0.
Preparation of Samples 9. F d-c charged Inductance,?
The technique of analyzing reference materials along 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.
