Sets out procedures for the preparation of test pieces from refractory materials by dry and wet gunning at ambient temperatures.

This Standard specifies the procedures for the preparation of test pieces from refractory materials by dry and wet gunning at ambient temperatures. NOTE: The values obtained from test pieces prepared using this method may not correspond with those obtained from test pieces of the same material prepared at a gunning installation site. This Standard does not apply to plastic gunning mixes.
