1.1 本规程包括使用折射计测定地板抛光剂中的不挥发物（总固体）。本规程也适用于地板抛光剂中使用的树脂溶液和蜡乳液。 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 根据试验方法，抛光剂、树脂溶液和蜡乳液的固体（不挥发物）测定需要2到4小时 D2834 ，不计算准备时间。 4.2 固体/折射率曲线提供了在几分钟内确定固体的方法。 4.3 本规程特别适用于抛光剂和抛光组件生产的质量控制和过程控制。

1.1 This practice covers the use of a refractometer for determining the nonvolatile matter (total solids) in floor polishes. This practice is also applicable to resin solutions and wax emulsions used in floor polishes. 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 Solids (nonvolatile matter) determinations of polishes, resin solutions, and wax emulsions take 2 to 4 h in accordance with Test Method D2834 , not counting preparation time. 4.2 Curves of solids/refractive index provide a means for determining solids in a matter of minutes. 4.3 This practice is particularly useful for quality control and in process control for the production of polishes and polish components.
