ISO 13517:2013规定了一种通过校准漏斗（Gustavsson流量计）确定金属粉末流动速率的方法，包括硬质合金粉末和金属粉末与有机添加剂如润滑剂的混合物。 该方法仅适用于通过指定试验孔自由流动的粉末

ISO 13517:2013 specifies a method for determining the flow rate of metallic powders, including powders for hardmetals and mixes of metallic powders and organic additives such as lubricants, by means of a calibrated funnel (Gustavsson flowmeter). The method is applicable only to powders which flow freely through the specified test orifice.
