4.Constant temperature and humidity test:
GB2423.393 Damp heat test :<Basic environmental testing procedures for electric and electronic products > test Ca: Damp heat test methods. (constant temperature and humidity test just meet the specified here)
1, Test temperature: 43 ℃ + 1.
2,Test humidity: 85%~98% + 2%RH.
3,By the use of steam, through the heat water to produce steam, and then into the working room. With the control of microcomputer processor, when the humidity does not meet the need of the value, is inching control; when the humidity exceeds the value, the dry hot air come into, will dilute the moisture and the excess the moisture is discharged. The humidification system using electronic and micro way humidification system (SSR driver).
A, Static room temperature experiment:
The cooling time is less than 15 minutes.
The external air is introduced into the cooling chamber so that the temperature of the test chamber is consistent with the outdoor temperature.
In the standard atmospheric pressure to do the static room temperature experiment, by the conventional spray test to the static placement experiment, mainly through two ways of cooling:
First, because the first step is the conventional spray test, so the test room temperature: 35 degrees, down to room temperature is at room temperature is used to blow air blower down to room temperature. The effect of static experiment second: if placed in a temperature, you specify, for example: 23 degrees in summer when it is difficult to achieve, you need to add a refrigeration system to achieve the purpose of cooling.
All of the test steps are programmed by the controller before the system has been set up, and achieve convergence.
