First, when doing environmental tests, we should be familiar with the sample performance, test conditions, test procedures and test technology required for the test, and then familiar with the technical performance of the test equipment used, the structure of the equipment, especially the operation and performance of the controller. Also carefully read the operation manual of the test equipment, so as to avoid the abnormal operation of the test equipment caused by the error of operation, resulting in the damage of the test sample, the incorrect test data.
Second, reasonable selection of test instruments and equipment. In order to ensure the normal conduct of the test, appropriate test equipment should be selected according to the different conditions of the test sample, and a reasonable proportion should be maintained between the effective volume of the test sample and the test chamber.
Third, place the test sample correctly. Test samples should be placed more than 10cm away from the box wall, and multiple samples should be placed on the same plane as far as possible. The sample should be placed without blocking the outlet and return air outlet, and a certain distance should be left for the temperature and humidity sensor. To ensure the correct test temperature.
