Metallic powders — Determination of flow rate by means of a calibrated funnel (Hall flowmeter) 金属粉末 - 通过校准漏斗测定流量（霍尔流量计）

发布日期： 2018-04-04

ISO 4490:2018规定了一种通过校准漏斗（霍尔流量计）测定金属粉末（包括硬质金属粉末）流速的方法。
该方法仅适用于自由流过规定测试孔的粉末。

ISO 4490:2018 specifies a method for determining the flow rate of metallic powders, including powders for hard metals, by means of a calibrated funnel (Hall flowmeter).
The method is applicable only to powders which flow freely through the specified test orifice.
