ASTM C973

ASTM C973 – Standard Practice for Preparing Test Specimens from Basic Refractory Gunning Products by Pressing

Description:

Significance and Use

2.1 This practice defines a procedure that ensures consistent preparation of specimens for product testing and evaluation.

2.2 This practice can be used in the laboratories of producers, users, and general-interest parties for research and development or quality-control work. It is particularly useful for interlaboratory comparisons on products, for repetitive evaluations or comparisons of products or product equality, and in specifying a uniform preparation practice for specimens for acceptance testing.

2.3 In using this practice, it must be recognized that the structure of laboratory-pressed specimens may differ significantly from the structure of material gunned in field applications.

Scope

1.1 This practice covers a procedure for preparing test specimens from basic refractory gunning products by pressing prepared material in a mold. After pressing, test specimens prepared from dolomitic mixes are subjected to a prescribed heat treatment. Specimens prepared in accordance with this procedure are intended for use in ASTM test methods.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
