A variety of such systems are commonly used. There shall be at least three calibrants for each element, spanning the required concentration range. The wall thickness of the mold should be 32 mm 1. Interference corrections will not be necessary if: 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.

The discharge is terminated at a predetermined level of accumulated radiant energy from the internal standard iron line or after a? 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? Successive excitations shall be sufficiently separated so that the discharge patterns do not overlap.

The radiant energy of selected analytical lines are converted into electrical energies by photomultiplier tubes and stored on capacitors. Flush, s Preburn, s Exposure, s 2 10 10 or 15 Argon Flow 0. A variety of such systems are commonly used. 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.

Make the necessary corrections either by adjusting the controls on the readout or by applying arithmetic corrections. 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. A minimum of three reference materials shall w1086 used for each element. If the readout is not in direct concentration units, use this value to obtain the concentrations from f1086 curves, or related scale values and concentration by reference to a table that has been previously prepared.

A variety of such systems are commonly used.

ASTM E1086 – 14

Your comments will receive careful consideration at a meeting ast, the responsible technical committee, which you may attend. Cracks, voids, pits, moisture, or inclusions will limit the sampling and the accuracy of a determination. 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 results for each individual laboratory is on? 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.

Examine the specimen after each excitation to evaluate the quality of excitation. Historical Version s – view previous versions of standard. Prepare the surface of the specimens and reference materials in a similar manner. If wet surfacing procedure is used, dry the specimens for proper excitation in the argon atmosphere.

These reference materials shall be homogeneous, and free of voids or porosity. Spectral lines are listed in Table 1.

Make a good electrical ground. If readings are not in conformance, repeat the standardization. Summary of Test Method 4. Grinding materials with grit sizes ranging from 60 to have been found satisfactory. Current edition approved Jan. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Calibration, Standardization, and Veri? The resulting surface should be uniformly plane and free of wstm. F d-c e086 Inductance,?

Position the specimen so there will be a uniform pattern of excitations around its face.

This procedure is suitable for manufacturing control and inspection testing. Cool the specimen after two excitations to prevent s1086, if required. Preparation of Samples 9. Precision and Bias 2 A number in parentheses indicates the year of last reapproval. Last previous edition approved in as E — 94 Electrode and argon are described in 7.

For example, a disk-shaped specimen should have a ring of excitation marks around its outer edge and approximately 6 mm 0.
