Make the necessary corrections either by adjusting the controls on the readout or by applying arithmetic corrections. Reagents and Materials 7.
The primary slit width is 20 to 50? Other internal standard and analytical lines, such as those listed in Table 2, may be used provided that it can be shown experimentally that equivalent precision and accuracy are obtained. Individual reprints single or multiple copies e4155 this standard may be obtained by contacting ASTM asm the above address or at phonefaxor service astm.
It is designed for chill-cast, rolled, and forged specimens. Means of changing the?
NOTE 2—Clean the excitation chamber when the counter electrode is replaced. Cut a 13 to mm 1? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.
A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Automatic sequencing shall be provided to actuate the? With a thoriated tungsten electrode, it ast, been reported that a hundred or more excitations can usually be made before replacement. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Once established, maintain the parameters consistently.
Repeat with different random sequences at least two times. Axtm previous edition E — With that equipment, a smooth, white, texture burn without the characteristic dark ring adtm an improperly excited specimen. Current edition approved Nov. Make certain that the specimens are homogeneous and free from voids and pits in the region to be excited Note 5. If results do not fall within the control limits established in 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.
H Resistance, V Peak voltage, V residual 2.
The following mold types have been found to produce acceptable samples: The specimen surface should be kept clean w415 the specimen is the electron emitter, and electron emission is inhibited by oily, dirty surfaces. However, because of differences between these CRMs and the production specimens prepared by the sampling procedures recommended for this test method, curves based on CRMs may in very unusual circumstances need to be corrected with values from reference materials made by normal production sampling techniques and analyzed in accordance with Test Methods E 30, Esatm E Print 1 2 3 4 5 page sstarting from page current page.
They are valuable in establishing preliminary working curves and determining the precision of the instrument. Nominal values found to be adequate are listed as follows: However, it is not required asmt all applications of this standard.

The spark chamber shall be mounted directly on the spectrometer, and shall be provided with a spark stand to hold a? Each laboratory should establish a suitable check procedure.
It is assumed that all who use this test method will be analysts capable of performing common laboratory procedures skillfully and safely.
