GSO ISO 4582:2015 塑料 测定暴露于玻璃、自然风化或实验室光源下的日光后的颜色变化和性能变化
Plastics -- Determination of changes in colour and variations in properties after exposure to daylight under glass, natural weathering or laboratory light sources
This International Standard describes procedures used to determine changes in colour and other appearance properties, and variations in mechanical or other properties, of plastics that have been exposed to daylight behind glass, to natural weathering or to light from a laboratory source. The procedure used to analyse data depends on whether the test used to characterize the materials being exposed is destructive or non-destructive. The exposures are conducted under conditions described in specific exposure standards.
