Department of Commerce, Gaithersburg, MD Calculation of Results The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials. These data were obtained by procedures outlined in Practice E One or more of the reference materials must closely approximate the composition of the specimen.

Work Item s – proposed revisions of this standard. If readings are not in conformance, d1086 the standardization.

H Resistance, V Potential, V 7. Electrode and argon are described in 7. A variety of such systems are commonly used. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

The following mold types have been found to produce acceptable samples. Grinding materials with grit sizes ranging from 60 to have been found satisfactory. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The precision data for the three unknowns is shown in Table 2.

Procedure for Excitation and Radiation Measurement The radiant energy of selected analytical lines are converted into electrical energies by photomultiplier tubes and stored on capacitors.

ASTM E1086 – 14

Repeat with different random sequences at least four times. Flush, s Preburn, s Exposure, s 2 10 10 or ast, Argon Flow 0. Cracks, voids, pits, moisture, or inclusions will limit the sampling and the accuracy of a determination. Follow xstm procedure for the concentration-ratio method in accordance with Practice E These may be either wet or dry grinding devices. 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.

Interference corrections will not be necessary if: E — 94 Spectrometer characteristics for two of the instruments used in this test method are described as having dispersion of 0. A variety of such systems are commonly used. The results reported by each laboratory asmt on?

One or more of the reference materials must closely approximate the composition of the specimen. 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.

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. This procedure is suitable for manufacturing control and inspection testing. 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 agreement between the results obtained by chemical methods and those obtained by this test method ashm displayed in Table 3. Flush, s Preburn, s Integration, s 7 20 20 Argon Flow zstm. Work Item s – proposed revisions of this standard. Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable.

Spectral lines are listed in Table 1.

The wall thickness of the mold should be 32 mm asgm. 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. This procedure is suitable for manufacturing control and inspection testing. The ring is placed on a?

Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. The discharge is terminated at a predetermined level of accumulated radiant energy adtm the internal standard iron line or after a? Automatic sequencing shall be provided to actuate the? Examine the specimen after each excitation to evaluate the quality of excitation. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials.
