1.1 This test method covers the procedures for determining the consistency of a castable using the ball-in-hand test. The amount of water used in a castable has a significant influence on its performance.

1.2 This test method applies to castable refractories that are described in Classification C401. It also applies to such castables containing metal fibers.

1.3 This test method is not intended to determine the proper consistency for gunning, pumping, or self-flow applications.

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (See 6.2.3 for a specific safety warning.)

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
