Abstract
A method is provided for measuring the tendency to and degree which a synthetic resinous particulate solid will block or agglomerate. The method comprises the steps of (a) forming a cake of a synthetic resinous particulate solid by compressing the particulate solid between substantially parallel surfaces at an elevated temperature, and (b) measuring the force required to break the cake by an elongated triangular-shaped wedge which is forced into the cake at a constant rate of speed.
