The test method of the constant temperature and humidity test chamber is constant humidity and heat. The common standard in the ring test industry is GB / T2423.9-2001 (the foreign general version is IEC60068-2-56: 1998). This standard is used to determine electrical and electronic products. Refers to the adaptability of the equipment for use and storage under high humidity conditions. This test is mainly used to observe the effect of the test sample at a constant temperature, no condensation, for a specified period of time and in a high humidity environment.
The constant temperature and humidity test chamber has several severe levels of different temperature, humidity and test duration for selection. It can be used for heat dissipation and non-heat dissipation test samples. If the user has a large sample, the non-standard walk-in constant temperature can be customized The wet test room is suitable for large-scale equipment or equipment that may have a complicated connection with the test device outside the test room during the test. This connection requires a certain assembly time. During the installation, it is not necessary to preheat or maintain specific test conditions.
When the constant temperature and humidity test box is being tested, the test sample and the test room are at room temperature. Place the test sample in the work room. The test conditions in the test room are adjusted according to the corresponding standards and maintained for a specified period of time. The temperature and humidity are very different from the specified test values, so the measurement of these parameters should be carried out according to the method used in free air conditions.
GB / T 2423.3-1993 Test chamber Ca: Non-condensing conditions in constant damp heat are obtained by preheating the test sample before entering the test room. In this test, the test sample is entered at room temperature Inside the box, and then heated to the specified temperature, the test process is carried out under the condition of no condensation.
