F d-c charged Inductance,? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The resulting surface should be uniformly plane and free of defects. If wet surfacing procedure is used, dry the specimens for proper excitation in the argon atmosphere. Avoid the center of cast specimens because there is more chance of quench cracks and segregation. The ring is placed on a?
The stand shall provide an atmosphere of argon and may be water cooled. Spectrometer characteristics for two of the instruments used in this test method are described as having dispersion of 0.
Place the freshly surfaced specimen on the excitation stand in a manner to effect a gas-tight seal and adequate argon? Prepare the surface to be analyzed on a suitable belt or disk grinder. 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.
H Resistance, V Potential, V 7. Link to Active This link will always route to the current Active version of the standard. There shall be at least three calibrants for each element, spanning the required concentration range. Reagents and Materials 7. Flush, s Preburn, s Integration, s 7 20 20 Argon Flow 0. The results for each individual laboratory is on? The agreement between the results obtained by chemical methods and those obtained by this test method is displayed in Table 3.
ASTM E1086 – 14
Examine the specimen after each excitation to evaluate the quality of excitation. Interference corrections will not be necessary if: It is the atm of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Make a good electrical ground. If readings are not in conformance, repeat the standardization. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Electrode and argon are described in 7. A variety of such systems are commonly used. This procedure is suitable for manufacturing control and inspection testing. B Either iron line These data were obtained by procedures outlined in Practice E Procedure for Excitation and Radiation Measurement A variety of such systems are commonly used. Referenced Documents purchase separately The documents listed below are referenced within e10086 subject standard but are not provided as part of the standard.
ASTM International – Standard References for ASTM E – 14
One or more of the reference materials must closely approximate the composition of the specimen. Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. Cool the specimen after two excitations to prevent overheating, if required.
Calibration, Standardization, and Veri? Last previous edition approved in as E — 94 The results reported by each laboratory are on? Repeat with different random sequences at least four times. Work Item s – proposed revisions of this standard.

Active view current version of standard. Summary of Test Method 4. Follow e086 procedure for the concentration-ratio method in accordance with Practice E These reference materials shall be homogeneous, and free of voids or porosity.
A superscript epsilon e indicates an editorial asrm since the last revision or reapproval. Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. Refer to Practice E Using reference materials supplied with the unknowns, in-house reference materials, NBS and British Certi? A number in parentheses indicates the year of last reapproval. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
The radiant energy of axtm analytical lines are converted into electrical energies by photomultiplier tubes and stored on capacitors.
