3 test conditions

Testing of exposed specimens under combined operating conditions is more severe than any single environmental condition test. There are three different methods for the combination of anti-damp heat and low pressure in optical instruments.

4 condition test

4.1 General The various parts of the sample were tested with a temperature difference between the test chamber (chamber) within 3K. The sample is allowed to show condensation. Each test The steps should be performed in the order they are. The test process is not allowed to interrupt. 4.2 conditions test method 47. hot and humid and low pressure, low pressure Condition test method 47 wet heat and low pressure, low pressure difference according to Table 1 and Figure 1. The conditional test method 47 is suitable for use in optical instruments where the sealing manufacturing requirements are low (low compressive resistance). For example. meet GB/T 12085.8 Test method 81 in the harsh rating of 01,02,07 and 08 of the instrument. Table 1 Severe Level 01 02 03 04 05 06 Test conditions 1 step 1 Test chamber (room) temperature/℃ 55 ± 2 63 ± 2 70 ± 2 Relative humidity /% < 40 Exposure time until the internal air temperature of the sample reaches the test chamber (room) within 3K Step 2 Climatic conditions 40 ℃ ± 2 ℃, relative humidity. 90% to 95% Exposure time/h ≥1 Number of cycles 6 12 6 12 6 12 ......
