The test purpose of the normal temperature low-pressure test chamber
Product name: Normal temperature type low-pressure test chamber
1. Purpose
The normal temperature low-pressure test chamber provides standard test procedures to determine the suitability of components, equipment or other products in a low-temperature/low-pressure comprehensive environment for use and/or storage.
2. General description
In the test, the test sample should first be subjected to the low temperature test of the severity level specified by the relevant specification. If the test sample needs to work during the test, it must be tested to ensure that the test sample can work normally. Then, while the temperature is maintained at the specified value, the pressure of the test chamber is reduced to the test pressure specified in the relevant specifications. Keep this temperature and pressure conditions for a specified time.
3. Test equipment
3.1 Manufacturer: Dongguan Huanyi Instrument
3.1.1 Test chamber
The normal temperature low-pressure test chamber does not apply to the temperature requirements of the chamber wall during the temperature and pressure changes. When restoring pressure and force, the auxiliary equipment and devices of the test chamber and the inviting air should be avoided to pollute the air in the test chamber.
4. Applicable to the test samples required to work in the test process during the *1h after the low air pressure time, intermediate testing according to the requirements of the relevant specifications. Cut off the power supply or unload the load before the air pressure is restored.
5. The pressure in the test chamber returns to the normal value at a rate not exceeding 10kPa/min, and temperature control is not required during the pressure increase. The sample is kept in the test box, and the temperature of the test box is gradually increased to the temperature range of the test standard atmospheric conditions at a rate of no more than 1 C/min (no more than the average time of 5 min).
