1.1 本试验方法包括测定密度为1.1的玻璃或无孔固体的密度 克/厘米 3. 至3.3 克/厘米 3. . 它可用于测定陶瓷或固体的表观密度，最好是已知孔隙度。 1.2 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。 1.3 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 玻璃密度的水槽-浮子比较仪测试方法提供了评估玻璃小片或样品密度的最准确（但便于实际应用）方法。 所获得的数据对于规范下的生产、验收或拒收的日常质量控制以及研发中的特殊目的非常有用。 4.2 尽管该测试范围仅限于1.1的密度范围 克/厘米 3. 至3.3克/厘米 3. 原则上，可通过使用其他混溶液体（试验方法）将其扩展到更高密度 F77 )例如水和丙二酸铊甲酸盐（约5.0 g/cm 3. ). 然而，在较高密度下，液体的稳定性和测试精度可能会有所降低。

1.1 This test method covers the determination of the density of glass or nonporous solids of density from 1.1 g/cm 3 to 3.3 g/cm 3 . It can be used to determine the apparent density of ceramics or solids, preferably of known porosity. 1.2 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. 1.3 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 The sink-float comparator method of test for glass density provides the most accurate (yet convenient for practical applications) method of evaluating the density of small pieces or specimens of glass. The data obtained are useful for daily quality control of production, acceptance or rejection under specifications, and for special purposes in research and development. 4.2 Although this test scope is limited to a density range from 1.1 g/cm 3 to 3.3 g/cm 3 , it may be extended (in principle) to higher densities by the use of other miscible liquids (Test Method F77 ) such as water and thallium malonate-formate (approximately 5.0 g/cm 3 ). The stability of the liquid and the precision of the test may be reduced somewhat, however, at higher densities.
