This Standard describes a procedure for laboratory preparation of test pieces from castable refractory materials.NOTE: The values obtained from test pieces prepared using this method may not correspond with those obtained from test pieces prepared using non-vibratory, or other vibratory, methods. This Standard applies to dense, mediumweight and lightweight castables containing either hydraulic cements or other binders. It does not apply to castable refractories intended primarily for gun application, or to low-cement castables.NOTE: Preparation of test pieces from low-cement castables is covered by AS 1774.4.2.A method for measuring the consistency of unshaped castable refractories is given in Appendix A.
