DIN ISO 4582:2025-12

This document specifies methods for determining changes in colour and other appearance properties, and variations in mechanical or other properties, of plastics that have been exposed to glass-filtered solar radiation, to natural weathering or to simulated solar radiation 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 specified in specific exposure standards (for example, the ISO 877 series and the ISO 4892 series). The responsible national standardization committee is Working Committee NA 054-01-04 AA "Verhalten gegen Umwelteinflüsse" ("Environmental resistance") at DIN Standards Committee Plastics (FNK).
