Water cooled xenon lamp aging test chamber SAE J1960 test method exposure conditions

2022-12-23

The water-cooled xenon lamp aging test chamber is a domestic experimental equipment independently developed and produced by our company QINSUN Instruments Co., Ltd. It is used for testing solar photovoltaics, plastics, paints, packaging, automotive materials, textile industries, including geotextiles, pigments, stabilizers, additives and other weather resistant materials.

Main parameters:

01. Light source: 6500W water-cooled xenon lamp tube ;

02. Spectral range: full spectrum sunlight;

03. Closed control range radiation intensity: (307~1356)W/m2(300~800nm) (Boro/Boro internal and external filters, see example for others );

04. Irradiation control accuracy: ± of the set value 0.1W/m2;

05. The irradiation intensity of the sample surface is uniform: ≦±4%;

06

Lab

. Irradiation control point: 340nm, 420nm, 300-400nm, 400-750nm, etc. can be selected;

07. Closed control range for blackboard temperature: BST: 40~120℃; BPT: 40~110℃;

08. The number of sample holders that can be installed: 65, a total of 3 layers;

09. The total exposure area: 6500cm2.

Exposure test method.

The exposure conditions in SAE J1960 are as follows:

1. In the light cycle, the irradiance is regulated at 0.55 W/m2 /nm@340nm;

2. UV extension filter (quartz inner filter / borosilicate outer filter);

3.70 ℃ blackboard temperature, run light for 40 minutes, relative humidity is 50%;

4. 20 minutes of light plus water mist, spray the front of the sample;

At a blackboard temperature of 5.38° C, turn for 60 minutes under light, and the relative humidity is 50%;

At a blackboard temperature of 6.38°C, 60 Add water mist in the dark for 1 minute, and sprayed before and back of the monster;

7. The position of the monster remains the same.
