We would like to introduce the high temperature and high humidity test, which is one of the factory tests.
What is "high temperature and high humidity test"?
High temperature and high humidity test is also a constant temperature and humidity test, is an environmental reliability test for equipment. That is to simulate the temperature and humidity environment of equipment storage and work, and check whether the impact of the product in this environment after a period of time is within the acceptable range.
The environments where products are stored and operated have certain temperature and humidity, and some of them have higher temperature and humidity. If the product is kept in such high temperature and humidity environment for a long time, the performance and life span will be affected to a certain extent. Therefore, it is necessary to carry out high temperature and high humidity testing of products to understand the performance of the product in this regard, and if it fails to meet the requirements, it is necessary to improve the product accordingly.
How to conduct high temperature and high humidity test
High temperature and high humidity test is with heating, cooling, humidification, dehumidification function of the equipment temperature and humidity box, before the test to check the product's related functions, performance, etc. is normal and take a picture, and then the product is placed in the temperature and humidity box, power on and set up the temperature and humidity box, humidity and the length of the test.
For example, 70°C, 95% humidity, test 168 hours. After setting, let the temperature and humidity box work and the test starts. After reaching the set end time, take out the product and check again what changes there are in the product's relevant functions and performance with that before the test, so as to judge whether the product meets the test requirements.
Picture
The high temperature and high humidity test has no fixed standard for the specific test temperature, humidity and test duration, which can be set with reference to the actual storage environment, transportation environment and use environment of the product.
The temperature is 40-80°C, the humidity is 65%-95%, and the duration ranges from ten hours to several hundred hours.
