1.1这些试验方法旨在作为短期试验，用于评估碳砖的物理性能及其在浸入服务中不同温度下的耐化学性。这些试验方法提供了一种确定碳砖试样和试验介质中以下变化的方法: 1.1.1碳砖试样的重量、外观和抗压强度。 1.1.2碳砖试样测试之前、期间和之后的测试介质外观。 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 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====== 4.1通过这些试验方法获得的结果应作为选择特定应用的耐化学性碳砖的指南，而不是唯一依据。未尝试将在各种实际使用条件下可能影响碳砖性能的所有因素纳入这些试验方法。

1.1 These test methods are intended for use as short-term tests for evaluating the physical properties of carbon brick and their chemical resistance at various temperatures in immersion service. These test methods provide a means of determining the following changes in the carbon brick specimen and the test media: 1.1.1 Weight, appearance, and compressive strength of the carbon brick specimen. 1.1.2 Appearance of the test media before, during, and after testing of the carbon brick specimen. 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 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 ====== 4.1 The results obtained by these test methods should serve as a guide in, but not as the sole basis for, the selection of a chemical-resistant carbon brick for a particular application. No attempt has been made to incorporate into these test methods all the factors that may affect the performance of carbon brick when subjected to various actual service conditions.
