According to the stop phase, the test chamber temperature should be close to a linear rate drops below the set temperature control values ??(typically set value + 25 ℃), and keep the temperature stable. Under different test procedures, the relationship between temperature, time of exposure and the test period is shown in Fig. 3 spectral energy distribution and Tolerance: Table 1 should meet the requirements of test time can be set within 0 ~ 999h, automatically according to the following test procedures were tested: Test Program A: In a 24-hour cycle, irradiation 8 hours, stop 16 photos hour test period can be set to test procedure B: a 24-hour cycle, illuminated 20 hours, stop according to four hours, 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 adjustable by frequency converter in the 0.5 ~ 1.5m / s range; with the equipment specification attached wind speed and frequency device table.
