5.2.2 Test Procedure Place a clean sheet of white cardboard (weighing over 350g) on the partition of the temperature/humidity test chamber (to observe whether the sample after the test is satisfactory). (To prevent leakage, the length and width of the paper should be larger than the corresponding dimensions of the sample). Place the sample on the white cardboard, turn on the test chamber, and set the temperature and humidity of the test chamber to within the specified range. Timing begins when the temperature and humidity reach 40°C and 90%. After 48 hours of constant temperature and humidity testing, the changes in the sample and individual products inside the chamber are observed and recorded.

5.2.3 Result Evaluation If any sample or individual product exhibits any of the following characteristics, the test result is considered unqualified.

---Sample combustion or explosion;

---The sample produces smoke or gas;

---Leakage occurred in the sample;

---External damage to the sample or significant changes in the appearance and structure of a single product.

5.3.1 Instruments and Equipment

5.3.1.1 Low temperature test chamber. (-35~-25)°C±2°C.

5.3.1.2 Automatic Temperature Recording System. Measures, records, and saves the temperature inside the test chamber in real time.

5.3.2 Test Procedure Place a clean sheet of white cardboard weighing over 350g on the partition of the low-temperature test chamber (to observe whether the sample leaks after the test). (The length and width of the paper should be larger than the corresponding dimensions of the sample.) Place the sample on the white cardboard, turn on the test chamber, and allow the chamber temperature to reach -35°C. Timing begins at -25°C. After 48 hours of constant temperature testing, the changes in the sample and individual products inside the chamber are observed and recorded.

5.3.3 Result Evaluation If any sample or individual product sample exhibits any of the following phenomena, the test result for this item is considered unqualified.

---Leakage occurred in the sample;

---External damage to the sample or significant changes in the appearance and structure of a single product.

5.4 Collision Test

5.4.1 Instruments and Equipment Impact test bench. The maximum load (including fixtures) should be greater than the mass of the specimen; the pulse waveform should be a half-sine wave; and the pulse frequency should be greater than

1 Hz. The maximum drop height is greater than 25mm.

5.4.2 Test Procedure

5.4.2.1 Adjust the drop height of the collision test bench to 25mm.

5.4.2.2 Place a clean sheet of white cardboard weighing at least 350g on the sample (to observe whether the sample leaks after the test; the length and width of the paper should be greater than the test sample). (The corresponding dimensions of the sample) On the worktable of the impact test bench, place the sample on a white cardboard sheet, and fix the sample to the worktable using clamps. Make sure the center of gravity of the sample is located at the center of the worktable.

5.4.2.3 Turn on the collision test bench, adjust the pulse frequency of the collision test bench to 1Hz, run it continuously for 1 hour, and then observe and record the results of the test sample and the test chamber. Changes in individual products.

5.4.3 Result Evaluation If any of the following phenomena are observed in any sample or individual product sample, the test result for this item shall be deemed unqualified.

---Sample combustion or explosion;

---The sample produces smoke or gas;

---Leakage occurred in the sample;

---External damage to the sample or significant changes in the appearance and structure of a single product.

5.5 Vibration Test

5.5.1 Instruments and Equipment Mechanical vibration test bench. The maximum load (including fixtures) should be greater than the mass of the specimen; the pulse waveform should be a sine wave; and the vibration frequency should be greater than 20Hz. The maximum displacement amplitude is 5mm.

5.5.2 Test Procedure

5.5.2.1 Place a clean sheet of white cardboard weighing at least 350g on the sample (to observe whether the sample leaks after the test; the length and width of the paper should be greater than the test sample). (The corresponding dimensions of the sample) On the worktable of the mechanical vibration test bench, place the sample on a white cardboard sheet and fix the sample to the worktable using clamps. Place the sample on the worktable surface and position its center of gravity at the center of the worktable surface.
