A variety of such systems are commonly used.

Link to Active This link will always route to the current Active version of the standard. Any of these that will achieve analytical accuracy equivalent to that reported for satm test method are acceptable.

These may be either wet or dry grinding devices. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Last previous edition approved in as E — 94 The discharge is terminated at a predetermined level of accumulated radiant energy from the internal standard iron line or after a?

ASTM E1086 – 14

These reference materials shall be homogeneous, and free of voids or porosity. Automatic sequencing shall be provided to actuate the? Spectral lines are listed in Table 1. F d-c charged Inductance,? These data were obtained by procedures outlined in Practice Asmt It is the responsibility of the user of this standard to establish appropriate asrm and health practices and determine the applicability of regulatory limitations prior to use. Successive excitations shall be sufficiently separated so that the discharge patterns do not overlap.

Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. Work Item s – proposed revisions of this standard. Examine the specimen after each excitation to evaluate the quality of excitation. Avoid the center of cast specimens because there is more chance of quench cracks and segregation.

Grinding materials with grit sizes ranging from 60 to have been found satisfactory. Flush, s Preburn, f1086 Exposure, s 2 10 10 or 15 Argon Flow 0.

Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. For example, a disk-shaped specimen should have a ring of excitation marks around its outer edge and approximately 6 mm 0. Work Item s – proposed revisions of this standard. Cracks, voids, pits, moisture, or inclusions will limit the sampling and the accuracy of a determination.

Qstm for Excitation and Radiation Measurement The precision data for the three unknowns is shown in Table 2. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and qstm as the reference materials.

Position the specimen so there will be a uniform pattern aastm excitations around its face. Link to Active This link will always route to the current Active version of the standard. Calculation of Results 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.

Equipment varies among laboratories. Department of Commerce, Gaithersburg, MD The samples must be sufficiently massive to prevent overheating during the atm and of a similar metallurgical condition and composition as the reference materials.

This procedure is suitable for manufacturing control and inspection testing. A minimum of three reference materials shall be used for each element. 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. Make a good electrical ground. Repeat with different random sequences at least four times.
