1.1 这些试验方法包括测定非瓷砖烧制的无釉陶瓷餐具的吸水率、堆积密度、表观孔隙率和表观比重的程序 2. 产品、有釉或无釉瓷砖和玻璃砖。 1.2 以公制单位表示的值为标准值。括号中给出的值是英寸-磅单位的数学转换，仅供参考，不规范。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。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，并确定监管限制的适用性。 1.4 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 密度、孔隙度和比重的测量是确定陶瓷体成熟度或确定特定应用可能需要的结构财产的工具。

1.1 These test methods covers procedures for determining water absorption, bulk density, apparent porosity, and apparent specific gravity of non-tile fired unglazed ceramic whiteware 2 products, glazed or unglazed ceramic tiles, and glass tiles. 1.2 The values stated in metric units are normative. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not normative. 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 ====== 3.1 Measurement of density, porosity, and specific gravity is a tool for determining the degree of maturation of a ceramic body, or for determining structural properties that may be required for a given application.
