BS PD ISO/TS 19022:2016

BS PD ISO/TS 19022:2016 specifies a test method which allows predicting the aging rate of materialspecimens, e.g. plastics, under interest independent of the aging mechanisms as a function of radiantexposure. The UV irradiance of a simulated solar radiation (with a laboratory radiation source) will beextended above the normal maximum level on earth surface while keeping all relevant temperatureparameters fixed.NOTE For translucent plastics, the surface temperatures are below the white standard temperature. Inaddition, the maximum temperature is not on the irradiated surface, it is somewhere inside the plastic material.Cross References:ISO 4582ISO 4892-1ISO 9370ISO 10640ISO/TR 17801 ISO 877-3ISO 4892-2ISO 4892-3ISO/TR 18486CIE Publication No. 85:1989
