The linearity and non-linearity of the constant temperature and humidity chamber are very different when testing. The following is an introduction to linear and nonlinear testing of equipment:
The linear test refers to the phenomenon that the difference ratio between the heating rate and the cooling rate is constant during a certain period of time during the working period of the constant temperature and humidity chamber. The national standard country is the average value every three minutes, such as: in a certain period of time, if the equipment can reach the specified heating value or cooling value within three minutes, then it is in the time period of the whole working operation. It will be three minutes and will remain fixed. In short, the temperature rate is the same as the initial temperature time.
The non-linear test refers to the phenomenon that the ratio of the difference between the heating rate and the cooling rate changes during a certain period of time during the working process. The non-linear test country specifies an average heating value or cooling value. For example, we set the specified time to three minutes, but the equipment can sometimes reach the specified heating or cooling value within three minutes, and sometimes it cannot be achieved. This phenomenon also indicates that the time of the whole work period is different, and often varies depending on the test sample.
The linear and non-linear tests of the constant temperature and humidity test chambers are not only different in the specified time, but also the environmental requirements they require.
