Page 3 EN ISO 4490:2001 Provläsningsexemplar / Preview Metallic powders Determination of flow time by means of a calibrated funnel (Hall flowmeter) 1 Scope This International Standard specifies a method for determining the flow time of metallic powders, including powders for hardmetals, by means of a calibrated funnel (Hall flowmeter). The method is applicable only to powders which flow freely through the specified test orifice. 2 Principle Measurement of the time required for 50 g of a metallic powder to flow through the orifice of a calibrated funnel of standardized dimensions. 3 Apparatus 3.1 Calibrated funnel, having the dimensions shown in Figure 1 (see clause 4). The funnel shall be made of a non-magnetic, corrosion-resistant metallic material having sufficient wall thickness and hardness to withstand distortion and excessive wear. 1) 3.2 Stand and horizontal vibration-free base, to support the funnel rigidly, e.g. as indicated in Figure 2. 1) 3.3 Balance, of sufficient capacity, capable of weighing the test portion to an accuracy of ± 0,05 g. 3.4 Stopwatch, capable of measuring elapsed time to an accuracy of ± 0,1 s. 3.5 Chinese emery grit, a reference powder used for calibration of the funnel. 1) 1) Apparatus complying with 3.1 and 3.2, and standard Chinese emery grit can be purchased from AcuPowder International, LLC, 901 Lehigh Avenue, Union, NJ 07083, USA. This information is given for the convenience of users of this International Standard and does not constitute an endorsement by ISO of the company named above. Equivalent products may be used if they can be shown to lead to the same results.
