Description

1.1 These test methods cover the measurement of apparent density, bulk factor, and where applicable, the pourability of plastic materials such as molding powders. Different procedures are given for application to the various forms of these materials that are commonly encountered, from fine powders and granules to large flakes and cut fibers.

1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
