SUNTEST XXL+ ST - Atlas

Advanced Automotive Component Testing with SUNTEST XXL+ ST

The Atlas SUNTEST XXL+ ST is an extra-large xenon weathering instrument especially tailored towards the needs of automotive parts testing. This dedicated model is designed for testing automotive interior and exterior methods per the Society of Automotive Engineers (SAE) J2412 and J1527 test methods, providing comprehensive weathering testing capabilities for automotive components.

Best-in-Class Testing Chamber Design

Its horizontal 2925 cm² exposure area and tall chamber height is best-in-class for 3-D specimens testing, allowing for easy testing of small-to midsized interior and exterior components such as trim, gaskets and door handles. The chamber’s extended height of 44 cm – unique for this class of xenon instrument – allows for better control of irradiation and temperature conditions.

SAE Standard Compliance

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. The instrument can also be configured for VW exterior standards PV3929 and PV3930 (Florida-Test).

Advanced Features for Accelerated Testing

Additional SAE-specific features that come standard include a specimen front spray and back spray system – both of which are fully pre-programmed on the touchscreen controller. The SUNTEST instrument allows for shorter test times by using extended UV filters that transmit more short wavelength UV into the test chamber than common Daylight filters, promoting further acceleration of the test.
