1.1在隔热水泥的应用中，湿覆盖能力和干燥后的体积变化通常非常重要。在确定干覆盖能力的同时，可以轻松确定这些特性。因此，本试验方法涵盖了确定这三种特性的程序。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.3以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法用于测定隔热水泥干燥后的湿覆盖和体积变化。

1.1 Wet covering capacity and volume change upon drying are often of major importance in the application of thermal insulating cement. These properties can be easily determined at the same time that the determinations of dry covering capacity are made. Therefore, the procedures for determining these three properties are covered together in this test method. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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. 1.4 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. ====== Significance And Use ====== This test method is used to determine the wet covering and volume change upon drying of thermal insulating cement.
