NOTE 13—The range of anode to cathode potentials for a given tube should be speci? Repeat with different random sequences at least two times.

ASTM-E, –

Center the analytical gap on the optical axes of the spectrometer. The number of acceptable excitations on an electrode varies from one instrument to e4155, and should be established in each laboratory.

Rough grind the cut surface by grinding on a belt surfacer, either wet or dry, with 50 to grit abrasive belt. The following mold types have been found to produce acceptable samples: Use either a 3, 4, or 5-mm If you like to ee415 a quick demo, let us know at support madcad.

Current edition approved Nov. Standardization will be done anytime veri? However, e41 boron nitride disks are used to mechanically restrict the excited area of the sample, a properly excited specimen may not exhibit a dark ring.

NOTE 2—Clean the excitation chamber when the counter electrode is replaced. Refer to Practice E for steel sampling procedures.

Users of this standard are expressly advised that determination of the e4155 of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. NOTE 9—The manner and frequency of positioning or checking the position of the exit slits will depend on factors such as: The potentials on the capacitors may be read directly, or a number of different readout systems may be employed which yield linear or logarithmic functions of the potentials and which may be displayed as relative numbers or as numbers calibrated directly in terms of percent.
