TM169/AATCC Xenon lamp aging test chamber

1. Black standard temperature or black panel temperature: When choosing the following two black standard temperatures for exposure test, refer to: 65℃±3℃ or 100℃±3℃ above temperature is not necessarily the preferred test temperature, when the relevant parties negotiate When consistent, other temperatures may also be selected, but should be stated in the test report, and if water spray is used, the temperature should be kept constant during the anhydrous period. If the thermometer cannot reach the specified temperature, the highest temperature reached during the absence of water shall be stated in the test report. The black standard thermometer takes measurements in a continuous fashion even though the exposure device is operating in an alternating fashion. If a black panel thermometer is used, the type of thermometer, its placement and the selected operating temperature shall be stated in the test report.

2. Relative humidity: The relative humidity used in the test should be agreed upon by relevant parties, so the relative humidity measured in the test chamber is not necessarily equal to the relative humidity of the air adjacent to the surface of the sample.

3. Water spraying cycle: The water spraying cycle used in the test should be agreed upon by relevant parties, but it is better to choose the following water spraying cycle: each spraying time: 18min±0.5min: water-free time between two spraying: 102min±0.5min

4. Dark cycle: The conditions specified in test methods 1 and 3 are applicable to the test of continuous light. The dark cycle can be a more complex cycle, such as a dark cycle with a higher relative temperature, during which the chamber temperature is raised and condensation is formed. The specific conditions of the dark cycle test should be stated in the test report.
