Testing with environmental test equipment is a relatively scientific and standardized work. In order for testers to obtain more accurate test data, we need to strictly follow the test procedures. Also for constant temperature and humidity test chambers, this should be the case when testing test samples.
Next, we will make some simple descriptions on the correct way of placing the sample to be tested in the constant temperature and humidity test chamber. When the test object is placed in the test chamber test area, how to place it is correct, and whether there is a requirement in the specification. What are the relevant aspects?
First, the sample to be tested should be placed in the middle of the box of the constant temperature and humidity test chamber. It should not cover the air duct above, nor can it be placed directly on the surface of the box. It needs to be adjusted according to the size, shape, weight and quantity of the sample to be tested. The distance between the sample holders and the placement method. If an external power supply is required, the wires should be connected to the test hole. Do not entangle the wires together. Pay special attention to the absence of damage or other dangerous factors.
Secondly, for some small parts, high and low temperature tests are required. Because the sample racks standard equipment manufacturers are mostly perforated, the aperture is about 5*5. If the product is small, the manufacturer should be informed in advance. The rack is encrypted or the tray is prepared by itself.
For the material of the sample to be tested, if the sample to be tested is liquid, it must be packed in a container of moderate size; if it is a volatile, flammable, explosive, self-igniting sample, do not set too high temperature. At the same time, it is also necessary to avoid liquid spillage; if it is rubber, it is necessary to use a plate mat to prevent the rubber from melting and adhering to the sample holder after being heated at a high temperature, which is very troublesome to clean.
For the above-mentioned precautions and specifications of the sample placement of the constant temperature and humidity test chamber, I hope to attract everyone's attention. After all, it is always correct to follow safe and correct test procedures.
