ASTM C974 – Standard Practice for Preparing Test Specimens from Basic Refractory Castable Products by Casting
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 or products, for repetitive evaluations or comparisons of products or product quality, 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-cast specimens may differ significantly from the structure of material cast in field applications.
Scope
1.1 This practice covers a procedure for preparing test specimens from a basic refractory castable by casting prepared material in a mold. 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.
