Weather tests on the new Xenotest 440
Atlas Material Testing Technology has released a new weathering instrument suitable for performing accelerated testing on plastic and other materials. The key features of the mid-sized, air-cooled xenon device, which has been named Xenotest 440, are speed and economy of resources.
The system uses lamp operating technology as well as ultrasonic humidifiers to reduce water consumption. XenoLogic is the name of the group’s twin-lamp operating technology which permits the instrument to reach high irradiance levels of 120 W/m2 of total UV radiation. By testing at higher irradiance levels, test times can be “significantly reduced” compared to standard weathering tests, claims Atlas.
XenoLogic is said to offer an extended lamp service life as it synchronises two 2200 W xenon lamps inside the chamber at the lowest possible stress level, which also leads improved light efficiency. Atlas says that the two xenon lamps combined can last over 4000 hours under standard testing levels of 40-60 W/m2. This increases instrument uptime and reduces lamp operating costs by as much as 30% or more.
The Xenotest 440 features a 10 x 6.8 cm test position (among others), which is suitable for plastic, paint and coating specimens.
