The black standard temperature or blackboard temperature of the xenon lamp aging test box is selected from the following two black standard temperatures for the exposure test. Refer to 65 ℃ ± 3 ℃ or 100 ℃ ± 3 (Note: The higher temperature is for special tests May make the sample more susceptible to thermal degradation and affect the test results.

The above temperature is not necessarily the preferred test temperature. When the relevant parties agree, other temperatures can also be selected, but it should be stated in the test report. ) If water spray is used, the temperature should be kept constant during the water-free period. If the thermometer cannot reach the specified temperature, the maximum temperature reached during the anhydrous period shall be stated in the test report. Even if the exposure device works in an alternating manner, the black standard thermometer should be measured in a continuous manner. If a blackboard thermometer is used, the type, placement and operating temperature of the thermometer should be stated in the test report.
Relative humidity of xenon lamp aging test chamber: The relative humidity used in the test should be agreed by the relevant parties. However, it is best to choose any of the following conditions:
(50 ± 5)% or (65 ± 5)% (Note: Because the temperature of samples of different colors and thicknesses is different, the relative humidity inside the test chamber may not necessarily be equal to the relative humidity of the air on the surface of the sample.)
Water spray cycle of xenon lamp aging test box: The water spray cycle used for the test should be agreed by the relevant parties. However, it is best to use the following spray cycle:
Each water spray time: 18m in ± 0.5m in, and the waterless time between two sprays: 102m in ± 0.5m in.
There is a test method in the standard called the dark cycle: the test conditions specified above apply to the continuous light test. The dark cycle can use a more complicated cycle, such as a dark cycle with higher relative humidity, during which the temperature of the test chamber is increased and condensation is formed.
We have professional quality control teams to make every shipment goods perfect and customer doesn't need worry about the quality problem to hurt his business reputation.
