The results reported by each laboratory are on? Satm corrections will not be necessary if: Follow the procedure for the concentration-ratio method in accordance with Practice E These data were obtained by procedures outlined in Practice E Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Precision and Bias 2 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 ring is placed on a? 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. Department of Commerce, Gaithersburg, MD Standardization will be done anytime veri?
Electrode and argon are described in 7. Spectrometer characteristics for two of the instruments used in this test method are described as having dispersion of 0. The following mold types have been found to produce acceptable samples. A variety of such systems are commonly used. E — 94 The stand shall provide an atmosphere of argon and may be water cooled.
Make a good electrical ground. 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 s1086. If wet surfacing procedure is used, dry the specimens for proper excitation in the argon atmosphere.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

A variety of such systems are commonly used. The radiant energy of asfm analytical lines are converted into electrical energies by photomultiplier tubes and stored on capacitors. Originally approved in The precision data for the three unknowns is shown in Table 2. Successive excitations shall be sufficiently separated so that the discharge patterns aetm not overlap. W1086 wall f1086 of the mold should be 32 mm 1.
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. Work Item s – proposed revisions of this standard. Cool the specimen after two excitations to prevent overheating, if required. It is the responsibility astj the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Prepare the surface to be analyzed on a suitable belt or disk grinder. Link to Active This link will always route to the current Active version of the standard. Equipment varies among laboratories. Work Item s – proposed revisions of this standard. A superscript epsilon e indicates an editorial change since the last revision or reapproval. A minimum of three reference materials shall be used for each element.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? This procedure is suitable for manufacturing control and inspection testing. Flush, s Preburn, s Exposure, s 2 10 10 or 15 Argon Flow 0.
ASTM E1086 – 14
This represents a total of 15 determinations. Position the specimen so there will be a uniform pattern of excitations around its face.
Using reference materials supplied with the unknowns, in-house reference materials, NBS and British Certi? The resulting surface should be uniformly plane and free of defects. Preparation of Samples 9. Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable.
Examine the specimen after each excitation to evaluate the quality of excitation.
