4、 Execution standards:

GB2423.2-89 Basic Environmental Testing Regulations for Electrical and Electronic Products

Experiment B: High temperature test method

① Temperature: 5-30 ℃ (temperature of the room where the test chamber is located)

② Relative humidity less than 85% RH

③ Atmospheric pressure: 86-106Kpa

④ There is no strong vibration around

⑤ No direct sunlight or direct radiation from other heat sources

⑥ There is no strong airflow around, and when the surrounding air needs to be forced to flow, the airflow should not be directly blown onto the box

⑦ No strong electromagnetic field influence around

⑧ There is no high concentration of dust or corrosive substances around

⑨ For the normal operation and convenience of the equipment, in addition to maintaining a horizontal placement, a certain space should be reserved between the equipment and walls or objects for maintenance and ventilation. (Generally greater than 0.6 meters)

⑩ Protect the grounding wire separately and do not share it with the grounding wires of other devices
