1.1 本试验方法涵盖了耐火材料在一氧化碳（CO）分解作用下的比较行为。测试方法是加速暴露于CO，以在相对较短的时间内确定潜在的材料行为。 1.2 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.4 本国际标准是根据《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的世界贸易组织技术性贸易壁垒（TBT）委员会发布的离子。 ======意义和用途====== 2.1 本试验方法用于测定各种耐火材料对暴露于一氧化碳气氛中引起的崩解的相对抵抗力。通过该方法获得的结果可用于选择耐CO分解的耐火材料。 2.2 该试验方法适用于研发和建立质量标准验收的CO崩解标准。 2.3 在大多数使用环境中，通过提供比预期更高浓度的CO来加速试样的崩解。对试样的影响可能不同于在实际使用条件下对耐火材料的影响。

1.1 This test method covers the comparative behavior of refractories under the disintegrating action of carbon monoxide (CO). The test method is an accelerated exposure to CO to determine potential material behavior in a relatively short time. 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, 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 ====== 2.1 This test method is used to determine the relative resistance of various refractories to disintegration caused by exposure to a CO atmosphere. The results obtained by this method can be used to select refractories that are resistant to CO disintegration. 2.2 This test method is suitable for research and development and for establishing CO disintegration criteria for specification acceptance. 2.3 The disintegration of test specimens is accelerated by providing a higher concentration of CO than anticipated in most service environments. The effects on the test specimens may be different than those found for refractories in actual service conditions.
