1.1 本规程涵盖根据规程烧制耐火混凝土（可浇铸耐火材料）试样 C862码 用于铸造试样。对于高温试验方法（如试验方法）所用的加热速率，也建议采用该程序 第16章 , C583号 等，当这些方法用于测试耐火混凝土时。 1.2 以英寸-磅单位表示的数值应视为标准值。括号中给出的值仅供参考。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 本规程用于标准化按照规程制备的耐火混凝土试样的烧成条件 C862码 制定这些标准是为了尽量减少实验室之间的差异，而不是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 Test 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== 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.
