Abstract
Overview
- adopted by CEN - defines a calibrated, reproducible . The standard specifies procedures to obtain comparable values of absorptance by calorimetric measurement: absorptance is reported as the ratio of radiant flux converted into heat and absorbed by the component to the incident radiant flux. The method assumes absorptance remains effectively constant during the temperature changes experienced in the test and notes that only thermally converted absorption is measured (non‑thermal processes are not detected).
