Plastics — Homopolymer and copolymer resins of vinyl chloride — Determination of compacted apparent bulk density

Specification of a method for the determination of the bulk density of PVC-polymers, densified by vibration under specified conditions. A weighed test portion is filled into a measuring cylinder and densified by means of a specified vibration apparatus. Calculation of the apparent bulk density from the weight and the measured volume after densification.
