ISO11507 UV Aging Test Chamber Weathering Test Machine

ISO 11507 is an international standard that specifies the exposure conditions for paint coatings in artificial weathering tests. The tests use fluorescent UV lamps and condensation or water spray. The tests simulate the degradation caused by exposure to sunlight and weather conditions. 

UV aging test chamber is applicable to predict the relative durability of non-metallic materials such as paint, coating and plastic through light-water exposure accelerated aging test.Especially suitable for observing the physical properties of particularly durable materials, such as gloss reduction, fading, fog shadow, strength reduction, pulverization, cracking, foaming and embrittlement.

As with other laboratory accelerated tests, the test results of this device cannot be used instead of natural exposure to determine the actual durability of materials, but the comparative test conditions provided by this device are quite practical for rapidly evaluating the anti-aging properties of materials, screening or improving new and old formulations, and monitoring product quality.

As ultraviolet light is the main factor that causes the deterioration of the durability of outdoor products, coupled with the relatively stable spectral energy distribution of fluorescent lamps and low price, ultraviolet light aging test box has become the most widely used weathering test machine in the world by virtue of its advantages of speed, convenience and economy.This device, as a simple model, is especially suitable for experiments with limited economic conditions.

The design of rotating plate frame adopted by this device can well compensate for the uneven light radiation caused by many factors such as lamp tube aging and different batches, thus saving the heavy workload of the general instrument which needs to change the plate position regularly in order.

Since moisture is an important factor in accelerating aging, this device USES water spray to simulate the influence of moisture.By setting the spraying time, we can get closer to some final environmental conditions, such as mechanical erosion favored by temperature change or rain erosion.

The device can also adjust the rate of photochemical reaction through temperature control mechanism in an appropriate range.

In order to meet the requirement of durability of weather tester, the structure of this device is made of corrosion resistant stainless steel.

With relatively low cost, you can understand the material damage that can be formed in a long period of time under natural conditions in a short time, and determine the quality gap between the test product and the high-quality sample.
