Annex A (informative) Factors that decrease the degree or
correlation between accelerated tests
using laboratory light sources and
actual-use exposures
Annex B (informative) Procedures for measuring the irradiance
uniformity in the specimen exposure area
Figure B.1 - Measurement of irradiance in devices using a
rotating specimen drum
Figure B.2 - Measurement of irradiance uniformity in devices
with a flat specimen plane
Figure B.3 - Typical plot of measured property for a reference
material showing a linear change with radiant
exposure and for a material that shows an induction
period before any measurable property change.
