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。试验方法是加速暴露在CO中，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====== 2.1 本试验方法用于测定各种耐火材料对暴露在CO大气中引起的崩解的相对阻力。 通过该方法获得的结果可用于选择耐共分解的耐火材料。 2.2 本试验方法适用于研究和开发，并适用于建立规范验收的共分解标准。 2.3 在大多数使用环境中，通过提供比预期更高的CO浓度来加速试样的崩解。对试样的影响可能不同于实际使用条件下耐火材料的影响。

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 and health practices and determine the applicability of regulatory limitations prior to use. ====== 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.
