Abstract
Overview
EN ISO 4892-2:2013/A1:2021 is the CEN-endorsed amendment to (Xenon‑arc lamps) for the accelerated weathering of . Amendment A1 adds an informative Annex C that introduces a formal used with xenon‑arc laboratory light sources. The change improves reproducibility and comparability of accelerated exposure results by specifying two daylight‑filter spectral types (Type I and Type II) and by clarifying how spectral irradiance is to be interpreted for Method A testing.
