This standard specifies a method for determining the apparent density of free-flowing plastic materials in powder or granular form using a specified funnel. The core of the method involves calculating density by measuring the mass of a known volume of material, which serves as a reference for evaluating the flowability of molding compounds and optimizing packaging and mold design. The key specialized instrument for conducting this test is the apparent density tester, which primarily consists of a base, a support frame, a funnel of specified dimensions, a baffle, and a 100-milliliter receiver (or measuring cup). During the test, the material is allowed to flow freely from the funnel into the receiver below, leveled, and then weighed to calculate the apparent density.
