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 asttm from reference materials made by normal production sampling techniques and analyzed in accordance with Test Methods E 30, Eand E It is expected that work will be performed in a properly equipped e4415.
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.
Using the averages of the data for each point, determine analytical curves as directed in Practices E and E NOTE 2—Clean the excitation chamber when the counter electrode is replaced. Work Item s – proposed d415 of this standard. Excitation and Radiation Measurements B Quantitative range in accordance with Practice E They are valuable in establishing preliminary working curves and determining the precision of the instrument.
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.
Masks shall be provided in the spectrometer to eliminate scattered radiation.
The data are given in Table 7 Note Better performance is expected when reference materials and specimens are of similar metallurgical condition and composition. The mass fraction ranges of the elements listed have been established through cooperative testing 2 of reference materials.
NOTE 14—With certain spectrometers, a properly excited specimen usually exhibits a dark ring around the pitted sparked area. It is assumed that all who use this test method will be analysts capable of performing common laboratory procedures skillfully and safely. Molecular gas impurities, nitrogen, oxygen, hydrocarbons, or water vapor, either in the gas system or from improperly prepared specimens should be minimized.
It is designed for either chill-cast or rolled and forged specimens. Astj your personal account email address to request a password reset: Print 1 2 3 4 5 page sstarting from page current page.
