英文名称：Coating powders — Part 2: Determination of density by gas comparison pyknometer (referee method)

发布日期：1992-12

标准范围

该方法可用于所有类型的涂层粉末，操作简单，但需要比通常用于密度测定更昂贵的仪器。它基于通过测量置换气体的体积来确定称重试验部分的体积。这是通过平衡由于气体置换而产生的压差来实现的。

The method can be used for all types of coating powder, is simple to carry out, but requires more expensive instrumentation than is often used for density determinations. It is based on the determination of the volume of a weighed test portion by measuring the volume of the gas displaced. This is achieved by equalizing the pressure difference which arises due to the displacement of the gas.
