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.
