    Significance and Use

    3.1 This practice is used to standardize the firing conditions of refractory concrete specimens prepared in accordance with Practice C862. The standards are set down to minimize laboratory-to-laboratory variation and do not attempt to duplicate any particular field applications.

    1. Scope

    1.1 This practice covers the firing of specimens made from refractory concretes (castable refractories) in accordance with Practice C862 for cast specimens. The procedure is also recommended for heating rates to be used for high-temperature test methods such as Methods C16, C583, etc., when these methods are used to test refractory concretes.

    1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
