Make certain that the specimens are homogeneous and free from voids and pits in the region to be excited Note 5. NOTE 10—When astmm values are established, maintain them carefully.
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.
If within the potential range the tube is either too sensitive or too insensitive for the element concentration range, select another photomultiplier. The reference materials and specimens should be of similar metallurgical condition and composition. Remember me for one month. Last previous edition E — B Interferences are dependent upon instrument design, dispersion, spectrum line choices, and excitation conditions, aetm those listed require con?
The spark chamber shall be mounted directly on e41 spectrometer, and shall be provided with a spark stand to hold a? The absorption of the radiation by air in this region is overcome by evacuating the spectrometer and?
It is designed for either chill-cast or rolled and forged specimens. The number of acceptable excitations on an electrode varies from one instrument to another, and should be established e41 each laboratory. The mass fraction ranges of the elements listed have been established through cooperative testing 2 of reference materials. Each laboratory should establish a suitable check procedure.
Secondary slit width is 50 to ? Excitation and Exposure Using the averages of the data for each point, determine analytical curves as directed e15 Practices E and E NOTE 14—With certain spectrometers, a properly excited specimen usually exhibits a dark ring around the pitted sparked area.
A number in parentheses indicates the year of last reapproval. B Quantitative range in accordance with Adtm E Precision and Bias Means of changing the?
The mass fraction ranges of the elements listed have been established through cooperative testing 2 of reference materials. Masks shall be provided in the spectrometer to eliminate scattered radiation.
ASTM E415 – 17
Other internal standard and analytical lines, such as those listed in Table 2, may be used provided that it can be shown experimentally that equivalent precision and accuracy are obtained. The specimen thickness should be between 10 e451 38 mm.
The ring is placed on a? 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.
There were no books found for the applied search filters. Preparation of Apparatus NOTE 7—The instructions given herein apply to most spectrometers; however, some settings and adjustments may need to be varied, and additional preparation of the equipment may be required. They are valuable in establishing preliminary working curves and determining the precision of the instrument.
These cover all or part of the concentration ranges listed in 1. Better performance is expected when reference materials and specimens are of similar metallurgical condition and composition.
