Abstract
Overview
ISO 1265:2007 - Plastics - Poly(vinyl chloride) resins - Determination of number of impurities and foreign particles - defines a visual, quantitative method for assessing particulate contamination in flattened surfaces of poly(vinyl chloride) (PVC) resins. The standard specifies a controlled counting procedure using a glass plate with a 300 mm × 300 mm grid and a rigid backing plate covered with glazed white paper. It is due to their finely divided state.
