GBT 16913-2008粉尘物理试验方法 粉尘安息角测定仪（注入限定底面法）

GBT 16913-2008 powder physical test method of powder angle of repose tester (injection limit underside method)

该产品供生产、经营、使用单位实验室对粉尘的物理性能测定使用。

The product is used for the physical performance of powder in production, operation and use of unit laboratories.

二、原理Principle:

将足够满溢料盘的粉尘从漏斗口注入到水平料盘上；测量粉尘堆积斜面与底部水平面所夹锐角，即粉尘安息角。

Inject enough powder from the funnel into the horizontal disc.Measure the acute angle between the incline and the bottom of the surface of the powder, namely the powder angle of repose
