1.1本试验方法涵盖了通过流动表法测定可浇铸耐火材料混合物稠度的程序。 1.2本试验方法适用于C 401类中所述的常规重量浇注耐火材料、绝缘浇注耐火材料和成型时需要剧烈振动的浇注耐火材料。它们也适用于含有金属纤维的此类浇注料。 1.3以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.4本标准无意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。

1.1 This test method covers the procedure for determining the consistency of castable refractory mixes by the flow table method. 1.2 This test method applies to regular weight castable refractories, insulating castable refractories, and castable refractories that require heavy vibration for forming, which are described in Classification C 401. They also apply to such castables containing metal fibers. 1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use.
