ASTM E2050用燃烧红外线吸收法测定压型粉中碳总含量的标准试验方法

ASTM E2050 Standard Test Method for Determination of Total Carbon in Mold Powders by Combustion-Infrared Absorption Method
ASTM E2050 用燃烧红外线吸收法测定压型粉中碳总含量的标准试验方法

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 ASTM E 882.

1. Scope
1.1 This test method covers the determination of total carbon in mold powders in the concentration range from 1 to 25 %.
1.2 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.
