Scope

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.
