The “Powder in Flexible Die”-test, or PFD-test for short, proposes a new way of testing plastic properties of granular materials. The principal idea for the test originates from Dr. J.I Bech. The test has since been developed further and refined at IPL-DTU. The present work describes the equipment used for the test and gives a detailed description of the practical steps necessary to perform the test.
