AbstractTo characterize weather as it affects plastics, measurements of surface temperature of opaque PVC panels subjected to outdoor exposure at five orientations in Ottawa, Canada, have been taken hourly for a year. Readings taken during Clear Hour periods, both day and night, have been selected, and for each panel the corresponding average daily surface temperature-time curve for each month was determined. These curves should be generally applicable to other common opaque plastics in service. They provide better appreciation of the temperature conditions to which plastics may be subjected, permit attainment of more realistic laboratory simulation of weathering, and provide input for equations predicting the behaviour of plastics on exterior exposure.
