1.1本实施规程涵盖了耐火混凝土（可浇铸耐火材料）制成的试样的烧制，符合铸造试样的实施规程C862。当高温试验方法（如方法C16、C583等）用于测试耐火混凝土时，也建议将该程序用于高温试验方法的加热速率。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 3.1本规程用于标准化按照规程C862制备的耐火混凝土试样的燃烧条件。制定这些标准是为了最大限度地减少实验室之间的差异，并且不试图复制任何特定的现场应用。

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. ====== 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.
