1.1 本规程涵盖在实验室条件下混合、浇注和养护整体耐火混凝土试样，以用于进一步测试。它不适用于主要用于喷涂应用的整体浇注耐火材料。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 具体试验方法需要不同的试样尺寸。参考这些试验方法，以确定样品的尺寸和数量，这将是样品所需的。 1.4 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、健康和环境实践，并确定监管限制的适用性。 1.5 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 本规程用于标准化其他测试方法下用于测试和评估的耐火混凝土试样的混合、模具条件、放置和养护。 3.2 本规程规范了生产耐火混凝土样本的实验室条件，以尽量减少实验室之间的差异，并且不试图复制现场安装的条件。 3.3 本规程可用于制备裁判测试中使用的试样。

1.1 This practice covers the mixing, casting, and curing of monolithic refractory concrete specimens under laboratory conditions for use in further testing. It does not apply to monolithic castable refractories intended primarily for gunning applications. 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. 1.3 Various specimen sizes are required for specific test methods. Refer to these test methods to determine the size and number of specimens, which will be required from the sample. 1.4 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. 1.5 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 mixing, mold conditions, placement, and curing of refractory concrete specimens to be used for testing and evaluation under other test methods. 3.2 This practice standardizes laboratory conditions for producing refractory concrete specimens to minimize laboratory-to-laboratory variation and does not attempt to duplicate the conditions of field installations. 3.3 This practice can be used for the preparation of specimens used in referee testing.
