《GB/T 21354-2008粉末产品振实密度测定通用方法》由TC63(全国化学标准化技术委员会)归口,TC63SC1(全国化学标准化技术委员会无机化工分会)执行,主管部门为中国石油和化学工业联合会。
本标准规定了粉末产品振实密度测定的通用方法,即在一定条件下容器中的粉末振实。
1 Scope
This standard specifies a method for the determination of tap density, i.e. the density of a powder that has been tapped in a container under specified conditions.
2 Principle
A specified amount of powder in a container is tapped by means of a tapping apparatus until no further decrease in the volume of the powder takes place. The mass of the powder divided by its volume after the test gives its tap density.
The tapping may be carried out by hand.
