ASTM-B964 › Standard Test Methods for Flow Rate of Metal Powders Using the Carney Funnel
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 These test methods cover the determination of a flow rate, by use of the Carney funnel, of metal powders and powder mixtures that do not readily flow through the Hall funnel of Test Method B 213.
1.2 This is a non-destructive quantitative test performed in the laboratory.
1.3 The values stated in SI units are to be regarded as standard. The values stated in parentheses are for information only, converted according to IEEE/ASTM Standard SI 10.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
The rate and uniformity of die cavity filling are related to flow properties, which thus influence production rates and uniformity of compacted parts.
The ability of a powder to flow is a function of interparticle friction. As interparticle friction increases, flow is slowed. Some powders, often fine powders and lubricated powder mixtures, may not flow through the Hall funnel of Test Method B 213.
Test Method B 213.
Humidity and moisture content influence flow rate. Wet or moist powders may not flow through either the Hall or the Carney funnel.
These test methods are based on flow of a specific mass of powder. If flow of a specific volume of powder is preferred, Test Method B 855
These test methods may be part of the purchase agreement between powder suppliers and powder metallurgy (PM) part producers, or it can be an internal quality control test by either the supplier or the end user.
