Standard Practice for Preparing Refractory Specimens by Cold Gunning

Importancia y uso:

3.1 The properties of refractories can be affected by their method of installation. This practice attempts to minimize the variables encountered during installation by pneumatic gunning.

3.2 This practice provides parameters to produce gunned specimens for use in other ASTM test methods.

3.3 This practice may be used to produce specimens for acceptance testing, service evaluation, manufacturing control, and research and development.

3.4 Differences between various kinds of equipment and the differences in procedures and operator techniques may result in significant variations in the physical properties of the gunned specimens. It is recommended that the same operator use the same equipment to produce specimens for referee testing agreed to by the involved testing parties. The specific operating parameters should be shown in the report.

3.5 Although this practice is specifically designed for refractories containing calcium aluminate cement, it may be used with minor modifications for gun mixes containing other bond systems.
