Significance and Use:

This test method is intended to be used for compliance with compositional specifications for silica content. It is assumed that all who use these procedures will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that 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 E 882.

Scope:

1.1 This test method covers the determination of silica in iron ores, iron ore concentrates and agglomerates, and manganese ore in the concentration range from 0.5 to 15 %.

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 oi this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
