This test method determines relative hydration resistance of magnesia grain.

This test method is used in industry to evaluate grain samples and is used for specification purposes in some cases.

Care must be taken in interpreting the data.

1. Scope

1.1 This test method covers the measurement of the relative resistance of magnesia grain to hydration.

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.

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