The agreement between the results obtained by chemical methods and those obtained by this test method is displayed in Table 3. Reagents and Materials 7. This procedure is suitable for manufacturing control and inspection testing.
ASTM E1086 – 14
Make the necessary corrections either by adjusting the controls on the adtm or by applying arithmetic corrections. Summary of Test Method 4. Work Item s – proposed revisions of this standard.
Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. Automatic sequencing shall be provided to actuate the? These data were obtained by procedures outlined in Practice E The following mold types have been found to produce acceptable samples.
The ring is placed on a? The discharge is terminated at a predetermined level of accumulated radiant energy from the internal standard iron line or after a? The precision data for the three unknowns is shown in Table 2.
Astmm lines are listed in Table 1. Excitation and Exposure One or more of the reference materials must closely approximate the composition of atsm specimen. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition asm composition as the reference materials.

Department of Commerce, Gaithersburg, MD Originally approved in The technique of analyzing reference materials along with unknowns and performing the e1806 mathematical corrections may also be used to correct for interference effects and to compensate for errors resulting from instrument drift. At the end of the exposure period, the charge on each capacitor is measured, and displayed or recorded as a relative energy or concentration.

This represents a total of 15 determinations. Interference corrections will not be necessary if: A minimum of three reference materials shall be used for each element. A superscript epsilon e indicates an editorial change since the last revision or reapproval. A number in parentheses indicates the year of last reapproval.
Equipment varies among laboratories. 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.
