SUPERSEDED (see Active link, below)
ASTM E2050
1. Scope
1.1 This test method covers the determination of total carbon in mold powders in the concentration range from 1 % to 25 %.
Note 1As used in this test method, percentage or % refers to a mass fraction of the form (wt / wt %) (g/100g).
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This test method has been evaluated in accordance with Practice E1601 and Guide E1763 . Unless otherwise noted in the precision and bias section, the lower limit in the scope of each method specifies the lowest analyte content that may be analyzed with acceptable error (defined as a nominal 5 % risk of obtaining a 50 % or larger relative difference in results on the same test sample in two laboratories).
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
