This part of ISO18549 describes two methods for the determination of the time (flow rate) it takes for a given quantity of a heated powder mix, based on iron or steel powders and to be used for warm compaction, to pass through a funnel with a given orifice diameter.
Method A uses a funnel with an orifice of 2,5mm and a test portion of 50g and is, to a large extent, based on the method standardized in ISO4490. The method can only be used for powder mixes that flow freely through the 2,5mm orifice in the heated condition.
Method B uses a funnel with an orifice of 5mm and a test portion with a size of 150g.
Both methods cover a testing temperature range of 60°C to 180°C and either of them can be selected after agreement between the parties involved.
