Abstract
Overview
ISO 4892-2:2013/Amd 1:2021 is an amendment to the international standard specifying methods for exposing plastics to laboratory light sources, focusing on xenon-arc lamps. This amendment introduces and defines the classification of daylight filters, which play a critical role in simulating natural sunlight under controlled conditions for the purpose of accelerated weathering and aging tests of plastic materials. Published by the International Organization for Standardization (ISO), this document supports the reproducibility and comparability of test results by providing a clear distinction between two main types of daylight filters.
