This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Spectral lines are listed in Table 1. A variety of such systems are commonly used. There shall be at least three calibrants for each element, spanning the required concentration range. Preparation of Samples 9. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory 1e086 prior to use.

If readings are not in conformance, repeat the standardization. The radiant energy of selected analytical lines are converted into electrical energies by photomultiplier tubes and stored on capacitors. Calculation of Results Calibration, Standardization, and Veri? Precision and Bias 2 Avoid the center of cast specimens because there is more chance of quench cracks and segregation. 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.

This procedure is suitable for manufacturing control and inspection testing. A variety of such systems are commonly used. Make the necessary corrections either by adjusting the controls on the readout or by applying arithmetic corrections.

One or more of the reference materials must closely approximate the composition of the specimen. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The d1086 must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials.

Spectrometer characteristics for two of the instruments used in this test method are described as having dispersion of 0. Link to Active This link will always route to the current Active version of the standard. W1086 view current version of standard. Originally approved in This procedure is suitable for manufacturing control and inspection testing.

Examine the specimen after each excitation to evaluate the quality of excitation. This represents a total of 15 determinations. The discharge is terminated at a predetermined level of accumulated radiant energy from 1e086 internal standard iron line or after a? Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

Electrode and argon are described in 7. These data were obtained by procedures outlined in Practice E The precision data for the three unknowns is shown in Table 2.

The agreement between the results obtained by chemical methods and those obtained by this test method is displayed in Table 3. Place the freshly surfaced specimen on the excitation stand in a manner to effect a gas-tight seal and adequate argon? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may r1086.

Successive excitations shall be sufficiently separated so that the discharge patterns do not overlap. Cracks, voids, pits, moisture, or inclusions will limit the sampling and the accuracy of a determination.

If wet surfacing procedure is used, dry the specimens for proper excitation in the argon atmosphere. Current edition approved Jan. Grinding materials with grit sizes ranging from 60 to have been found satisfactory.
