The crushing strength aids the pellet producer in the determination of quality problems associated with the production of pellets.

The crushing strength is often used by the pellet consumer as a quality indicator for performance in the blast furnace.

1. Scope

1.1 This test method describes a method for determining the crushing strength of fired iron ore pellets. Cylindrical agglomerates, briquettes, and reduced pellets are not covered by this test method.

1.2 The values as stated in SI units are to be regarded as the standards. 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
