Metallic powders - Determination of flow rate by means of a calibrated funnel (Hall flowmeter) (ISO 4490:2018) 金属粉末 - 通过校准漏斗(霍尔流量计)测定流量
发布日期: 2018-05-30
实施日期: 2018-05-30
ISO 4490:2018规定了一种通过校准漏斗(霍尔流量计)确定金属粉末(包括硬质金属粉末)流速的方法。 该方法仅适用于通过指定测试孔口自由流动的粉末。
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.
