1.1 The amount of water used in a castable mix for preparing test specimens has a significant influence on the test results. These practices cover procedures for determining and measuring the consistency of castable mixes in preparing specimens for two test methods:

1.1.1 Flow-Table Test.

1.1.2 Ball-in-Hand Test.

1.2 These practices apply to regular weight castable refractories, insulating castable refractories, and castable refractories that require heavy vibration for forming, which are described in Classification C401. They also apply to such castables containing metal fibers.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.

1.4 This standard does not purport to address all of the safety problems, 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.
