Abstract
Methods and apparatus for accurate service life prediction by exposing a test specimen to operating parameters of a multi-variable micro-environment cycle in an accelerated weathering test apparatus including an irradiance source, a temperature adjustment source and a moisture adjustment source connected to a controller to: expose the test specimen to the operating parameters of the multi-variable micro-environment cycle recreated in the test chamber; monitor the exposure of the test specimen to the multi-variable micro-environment cycle to generate run-time variables; and adjust the run-time variables to reconcile to the operating parameters.
