1.1 本试验方法涵盖取样、试样制备和建筑铸石吸收的测定。 1.2 本试验方法描述了两个程序:( 1. )冷水和( 2. )沸水。试验方法的使用者应规定所需的方法。如果没有规定，将使用冷水程序。 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、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本试验方法用于测定铸石的吸收率。吸收率是衡量铸石孔隙度的一个指标，因此也是衡量其耐候性和结构应力的一个指标。

1.1 This test method covers the sampling, preparation of specimens, and determination of the absorption of architectural cast stone. 1.2 This test method describes two procedures: ( 1 ) cold water and ( 2 ) boiling water. The user of the test method should stipulate which is desired. If no stipulation is made, the cold water procedure will be used. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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 ====== 4.1 This test method is to be used in determining the absorption of cast stone. Absorption is one measure of porosity of cast stone and, hence, its resistance to weathering and structural stress.
