Thermostatic test chamber IP/DP Box®

temperatureagingdurability

The IP/DP (Instrument Panel/Door Panel) Box® offers an accelerated temperature limiting under glass weathering method to determine the durability and/or colorfastness of many materials. This box simulates the conditions found in the interior of an automobile. It is used primarily but not exclusively for automotive interiors. Innovative uses have included the testing of headphones, remote control devices, CD covers and window tinting films. This under glass exposure cabinet was primarily designed to accommodate non-standard specimen sizes such as complete automotive assemblies as well as standard 10 x 15 mm (4 x 6 in) samples. Controlled azimuth tracking (Arizona only) for maximum solar irradiance and fixed 45° angle facing south (Arizona and Florida) methods are available. A temperature limiting feature prevents the interior of the box from exceeding a maximum temperature by activating a linear axial fan which directs uniform air flow over the test specimens. The fan is turned off when the temperature falls 3°C (5°F) below the set point. An automatic curtain is released to shield the samples from irradiance should the black panel temperature rise less than 6°C (11°F) above the set point. Various types of windshield or side window glass can be installed for evaluating the effects of different types of glass on automotive interior components. Color, gloss measurements and visual inspections are performed at intervals according to applicable test standards or client specifications.
