Hardware environment climate test items and criteria
Category: Temperature
Subcategory: Working temperature and humidity test, test for 5 days
Temperature range: 5-25 degrees
Item:
1) Low temperature change 5-25 degrees, 20 degrees/hour, (equipment power off state , Humidity is not controlled)
2) Low temperature soaking, 5 degrees/4 hours, (equipment power off state, humidity is not controlled)
3) Low temperature power on and off, 5 degrees, 150 times (power on time 5 minutes, power off time 1 minute)
4) Low temperature work, 5 degrees/24 hours, (run the pressure test tool, record the system operation every 15 minutes)
5) High temperature changes, 5-35 degrees, 20 degrees/hour, (equipment power off state, humidity is not controlled )
6) High temperature soaking, 35 degrees/4 hours, (set humidity reaches 85% within 2h)
7) High temperature power on and off, 35 degrees, 150 times (upper humidity 50%, power on time 5 minutes, power off time 1 Minutes)
8) Temperature drop, 35°-25°C, 20°C/hour,
9) Storage temperature and humidity test (3 days) (25°C, 50%RH)
10) Temperature drop 25°~-40°C, 3°C/ Hours, (power off the equipment)
11) Low temperature storage, -40 degrees, 24H
12) Temperature rise, -4~65 degrees, 30 degrees per hour,
13) High temperature storage, 65 degrees, 4h, 50%RH,
14) High temperature Humidification, 65 degrees, 50%~95%, (the thermostat reaches 95% within 2h)
15) High temperature and high humidity, 65 degrees, 95%, 24h,
16) High temperature and humidity reduction, 65 degrees, 95%-50%, (Humidity drops to 50%RH within 1h)
17) Cooling and normal humidity, 65-25 degrees, 50%RH, 30 degrees/hour,
18) Take out test, electrical performance test and appearance test (
test after standing at room temperature for 2 hours) 19) Thermal test, at 35 degrees, point thermometer pays attention to the temperature rise of key nodes inside the equipment, equipment running pressure;
20) Noise test, noise Less than 78dbA, 25 degrees room temperature rotation speed and high temperature full speed,
21) Low air pressure test, ensure that the altitude is below 3000 meters;
22) High and low temperature limit, (generally not tested)
