About This Item
ASTM B964 is the ASTM standard for Standard Test Methods for Flow Rate of Metal Powders Using the Carney Funnel. It provides a consistent way to evaluate how metal powders move through a specified funnel arrangement, which is important for comparing powder behavior in a repeatable test setup. For organizations involved in powder production, purchasing, or quality control, this standard helps support more reliable testing and better material consistency decisions.
Overview of ASTM B964
The Standard Test Methods for Flow Rate of Metal Powders Using the Carney Funnel focuses on measuring flow behavior under a defined test condition. ASTM B964 is used to establish a common approach to flow rate evaluation so results can be compared more confidently across batches, suppliers, or internal testing programs. As an ASTM standard, it is especially relevant where powder handling performance needs to be checked in a controlled and repeatable way for technical review or acceptance purposes.
Common use cases of ASTM B964
ASTM B964 is commonly used in metal powder testing environments where flow characteristics are part of routine quality assessment. It may be applied during incoming inspection, production monitoring, product development, or supplier qualification when metal powders must be evaluated with a standardized method. The test is also useful in workflows that depend on predictable powder movement, helping teams compare material lots using a recognized technical document.
Benefits of using ASTM B964
Using ASTM B964 supports more consistent flow rate measurements and helps reduce variation in powder testing practices. That consistency can improve product evaluation, procurement decisions, and quality control records. For buyers and technical teams, the standard offers a clearer basis for comparing test results and supporting compliance with internal requirements or customer specifications. It also helps reduce ambiguity when reviewing metal powder performance data.
