Application sectors: aerospace, defense, electronics, electrical products Description: The main technical parameters of temperature range 10 ℃ ~ + 70 ℃ (no illumination) Notes: 1, all (otherwise specified) in empty condition, according to GB / T5170 Test 2, air-cooled chamber system at room temperature 25 ℃ under well-ventilated conditions and test data; when 35 ℃ ≥ room temperature> 25 ℃, it can be used normally, but the low temperature range, the cooling rate and thermal load capacity will be subject to a certain extent. 3, water-cooled chamber at temperature ≤28 ℃, the water pressure in 0.2MPa ~ 0.6MPa, under conditions out of the water pressure ≥0.2MPa test data temperature fluctuation ≤ ± 0.5 ℃ (no illumination) Temperature uniformity ≤2 ℃ (no illumination) Temperature deviation ± 2 ℃ (no illumination) Humidity range 40% ~ 98% RH (without illumination conditions) (see Figure humidity range) Humidity deviation + 2 ~ -3% (> 75% RH), ± 5% (≤75% RH) (no-light conditions) heating time ≤60min (room temperature ~ + 70 ℃) light intensity (700 ~ 1120) ± 10% W / m2 (adjustable) illumination time adjustable 2 1 0 ~ 99h99min during irradiation, the test chamber temperature should rise to close to a linear rate and maintained at the temperature control set value (typically set the value to + 55 ℃ and 40 ℃). 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.
