High and low temperature low pressure test chamber performance and index requirements High and low temperature low pressure test chamber performance and indicators requirements are as follows:
Temperature grade: high temperature 30 ° C, 40 ° C, 55 ° C, 70 ° C, 85 ° C, 100 ° C, 125 ° C, 155 ° C,
175 ° C, low temperature 5 ° C, -5 ° C, -25 ° C, -30 ° C, -40 ° C, -55 ° C, -65 ° C.
Temperature deviation: ± °C at atmospheric pressure test; ±3 °C at ≤100 °C for comprehensive test of temperature and low pressure,
>100 ° C ~ 200 ° C ± 5 ° C.
Temperature gradient: ≤ 2 ° C
Temperature fluctuation: ≤1.0°C
The difference between the temperature of the inner wall of the studio and the temperature of the working space: at the high temperature level, it should not be higher than 3% of the temperature of the high and low temperature low pressure test chamber; when the low temperature level is not higher than 8% of the temperature of the test chamber.
Air pressure rating: 84kPa, 79.5 kPa, 70 kPa, 61.5 kPa, 55 kPa, 40 kPa, 25 kPa,
15 kPa, 8 kPa, 4 kPa, 2 kPa, 1 kPa.
Air pressure deviation: ±2 kPa at 84 kPa to 40 kPa; ±0.5 kPa at 25 kPa to 40 kPa; ≤2 kPa
±0.1 kPa.
Increasing and cooling rate: Calculated every 5 minutes, the average rate is not more than 1 °C / min; or the fastest rising and cooling time.
Air pressure change rate: ≤10 °CkPa
Wind speed: ≤1m/s or adjustable.
Note: In the low temperature and low pressure test, if the air pressure is lower than 10 kPa, or the high temperature and low pressure test, if the air pressure is lower than 4 kPa,
The temperature deviation can be appropriately relaxed; the manufacturer should specify the fastest heating time and cooling time in the product technology folder; the manufacturer can specify the wind speed adjustable range in the product technical documentation.
