Significance and Use | ||||||||||||||
This test method for the determination of total carbon in mold powders is primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory and that proper waste disposal procedures will be followed. Appropriate quality control practices must be followed such as those described in Guide E882. |

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 1—As 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. |
