Weathering testing of materials & components under extended UV conditions

SKU: 2f899891de9b Categories: , ,


The Atlas SUNTEST XXL+ ST is an extra-large xenon lamp flatbed instrument especially tailored towards the needs automotive parts testing. A dedicated model for testing automotive interior & exterior methods per the Society of Automotive Engineers (SAE) J2412 and J2527 test methods.

Its horizontal 2925 cm2 exposure area and tall chamber height is best-in-class for 3-D specimens testing.

The SUNTEST XXL+ ST is used to test automotive interior trim components against their hot lightfastness (SAE J2412) and automotive exterior materials against their weather-fastness (SAE J2527). Both protocols were developed by the American automotive industry and both use extended amounts of short wavelength UV to promote further acceleration of the test (exterior J2527 has a daylight spectrum option).
