Significance and Use:

This test method is a comparative method intended primarily to test materials for compliance with compositional specifications or for monitoring. 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.

This test method is used to monitor the feed to blast furnaces for process control.

Scope:

1.1 This test method covers a relative measure of the resistance of iron ore pellets and sinter to degradation by impact and by abrasion.

1.2 The values as stated in SI units are to be regarded as the standard. The values in parentheses are given for information only.

1.3 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.
