According to the stop stage, the temperature of the test chamber should be close to a linear rate drops at a temperature control set value (typically set value + 25 ℃), keeping the temperature stable. Under different test procedures, the relationship between temperature, irradiation and time during the test is shown in Fig. 3 spectral energy distribution and Tolerance: should meet the requirements of Table 1 test time can be set within 0 ~ 999h, the following test procedures can automatically test: Test procedure A: to 24 hours for a cycle, irradiation 8 hours, stopping 16 photos hour test period can be set to the test procedure B: a 24-hour cycle, illuminated 20 hours, according to four hours to stop the test cycle can be set. Test procedure C: continuous irradiation, the test time can be set. Lamp cooling air-cooled (under normal conditions of use, the effective life of metal halide lamp 800 to 1000 hours) wind chamber wind speed is adjustable by inverter within 0.5 ~ 1.5m / s range; with the device attached manual wind speed and frequency device table.
