After the test, check that the insulating parts such as the shell should not have defects such as deformation, cracking and color. 5.13 Condensation heat test
The test is carried out according to the method specified in CB1146.5. After 55C and two cycles of testing, it is restored under normal atmospheric conditions and the main performance test is completed within 2 hours. It should meet the following requirements: Reliable operation:
The insulation resistance should meet the requirements of Article 4.8 of this standard; the corrosion surface of the electroplated parts shall not exceed 25%, and the main metal of the parts shall not have rust spots; c.
Painted parts are allowed to have slight gloss loss and discoloration, a small number of pinholes and other defects, and bubbles with a diameter greater than 1mm are not allowed; d.
The adhesion of the paint film is in nine 1mm squares, and the primer does not fall off or the topcoat does not fall off more than 1/3 of the area; e. Insulating materials and rubber and plastic parts shall not have defects such as deformation, stickiness, and cracking. 5.14 Low temperature test
The test is carried out according to the method specified in CB1146.2, with a test severity of -25C and a time of not less than 0.5h. The product should be able to work normally during the test. After the test, check that the shell and other insulating parts should not have defects such as deformation, cracking and fading. 5.15 Vibration test
The test is carried out according to the test method specified in CB1146.9. When the frequency is 2-10Hz, the displacement is ±1mm; when the frequency is 10-80Hz, the acceleration is ±4m/s; the test product is scanned 13 times at 1 times the frequency/min to check for resonance, and then a 2h endurance vibration test is carried out at the maximum resonance point. If the resonance point is particularly obvious, a 2h endurance vibration test is carried out at 30Hz. It is carried out in three axial directions (vertical, horizontal, and longitudinal) in sequence, and resonance with a magnification of more than 5 times is not allowed. After the test, the fasteners of the test product should not be loose and can work normally. 5.16 Drop test
Connect the plug to a flexible cable about 2250mm long and fix its free end to the wall. 750mm above the ground, as shown in Figure 9. Hold the test product to make the cable horizontal, and then let the test product fall on the concrete floor. Do this drop 8 times, each time making the cable rotate 45° at the fixed position. After the test, there should be no damage that affects continued use, and there should be no looseness. And it should be able to maintain IP56 waterproof performance.13 requirements. 5.10 The test of the breaking capacity of the switch socket shall be carried out in accordance with the test method of rated connection and breaking capacity in Chapter 7 of GB998, and shall comply with the requirements of Article 4.14 of this standard. 5.11 Temperature rise test
5.11.1 After the plug is inserted into the socket, the rated current is passed through each pole in series. After the temperature rise is stable, the temperature rise of the electrical contact part of the plug and socket is measured with a thermocouple, which shall comply with the requirements of Article 4.17.1 of this standard. 5.11.2 The test method of the temperature rise of the switch socket shall be carried out in accordance with Article 5.2 of GB998. And it shall comply with the requirements of Article 4.17.2 of this standard.
5.12 High temperature test
The test shall be carried out in accordance with the method specified in CB1146.3, the test severity is 1070℃, and the time is not less than 0.5h. The product shall be able to work normally during the test. After the test, check that the insulating parts such as the shell should not have defects such as deformation, cracking and color. 5.13 Condensation heat test
