If within the potential range the tube is either too sensitive or too insensitive for the element concentration range, select another photomultiplier. NOTE 12—A high-purity argon atmosphere is required at the analytical gap.
Current edition approved Nov. It is not within the scope of an ASTM test method to prescribe the minute details of the apparatus preparation which may differ not only for each manufacturer, but also for different equipment from the same manufacturer.
The wall thickness of the mold is approximately 32 mm 11? Masks shall be provided in the spectrometer to eliminate scattered radiation. In general this condition will not affect analytical performance for the?
The data are given in Table 7 Note Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Land Use and Development.
However, if boron nitride disks are used to mechanically restrict the excited area of the sample, a properly excited specimen may not exhibit a dark ring. Molecular gas impurities, nitrogen, oxygen, hydrocarbons, or water vapor, either in the gas system or from improperly prepared specimens should be minimized.
The number of acceptable excitations on an electrode varies from one instrument to another, and should be established in each laboratory. The ring is placed on a? If you like to setup a quick demo, let us know at support madcad. However, it is not required for all applications of this standard. The absorption of the radiation by air in this region is overcome by evacuating the spectrometer and?
The reference materials and specimens should be of similar metallurgical condition and composition. Included, in addition to the original data of Test Method E — 71, are data from cooperative testing of a broader range of reference materials to expand the element concentration ranges. These cover all or part of the concentration ranges listed in 1.
Means of changing the? With that equipment, a smooth, white, texture burn without the characteristic dark ring indicates an improperly excited specimen.

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.
Excitation and Exposure NOTE 8—The lines listed in Table 1 have proven satisfactory for the elements and concentration ranges described in the scope. Calibration, Standardization, and Veri? Other internal standard and analytical lines, such as those listed in Table 2, may be used provided e145 it can be shown experimentally that equivalent precision and accuracy are obtained.
There shall be at least three calibrants for each element, spanning the required concentration range. Are you sure you want to empty ast cart?
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. However, because of differences between these CRMs and the production specimens prepared by the sampling procedures recommended for this test method, curves based on CRMs may in very unusual circumstances need to be corrected with values from reference materials made by normal production sampling techniques and analyzed in accordance with Test Methods E 30, Eand E If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
It is designed for chill-cast, rolled, and forged specimens. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
