High and low temperature need to do a lot of factory quality evaluation items, the high and low temperature performance inspection and evaluation method comprising: a noise, safety, sealing, dripping condensation water, the quality of the appearance, the test results and the like. Below, Suzhou Baoyutong Testing Equipment Co., Ltd. explains for you one by one:
1. Inspection and evaluation method of the sealing performance of the door: a paper strip with a thickness of 0.1 mm , a width of 50 mm and a length of 200 mm is vertically clamped between any part of the door and the door frame, and the paper strip is gently pulled by hand, such as a paper strip. that is not slidably standard specifications (Note: this test checks 5.2 conducted once before the start and at the end).

  3. Test method for performance of safety protection device: 42 °C for Class I test chamber, 42 °C and 57 °C for test temperature of Class II test chamber , set the temperature of the alarm and protection device to the test temperature, and raise the temperature of the test chamber. . When the temperature of the center reaches the set temperature, a signal is sent before the alarm device, and the safety protection device should act immediately (Note: This test is carried out under full load conditions and should be carried out 3 times continuously ).
4, noise and Evaluation Method: Test Method chamber machine noise see ZB N61 012, the results should be consistent with the provisions of Article 4.3.3.
 5. Inspection and evaluation method of condensation water drop in the working space of high and low temperature test chamber: visually observe the size of the condensation water on the top surface of the working chamber and whether it is filled in the working space. If the water drops are in the working space, it will meet the requirements of the standard.
  6, Evaluation of test results: During the test, and protective devices such as alarm every time when the operation, i.e., standard specifications.
