Plastics. Methods for determining the density of non-cellular plastics - Density gradient column method Ingestion-build-260237 Terms used in ultrasonic testingWhat is this standard about? This document specifies a gradient column method for the determination of the density of non cellular moulded or extruded plastics or pellets in void free form. Density gradient columns are columns containing a mixture of two liquids, the density in the column increasing uniformly from top to bottom. NOTE Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can
