Road LED Text Reliability Test

Road LED Text Reliability Test

Environmental resistance test:

Vibration test, transportation package drop test, temperature cycle test, temperature and humidity test, impact test, waterproof test

Durability test:

High and low temperature preservation test, continuous switch operation test, continuous action test

LED display reliability test conditions finishing:

Vibration test: three-axis (XYZ) vibration, 10 minutes each, 10 ~ 35 ~ 10Hz sine wave, 300 ~ 1200 times/min, 3 minutes per cycle, vibration Fu 2mm

Vibration tightening test: vibration + temperature (-10 ~ 60℃)+ voltage + load

Drop test for transport packaging: Drop material slurry (at least 12mm thick), height depends on the purpose of use

Temperature cycle:

a. No boot test: 60℃/6 hours ← Rising and cooling for 30 minutes →-10℃/6 hours, 2cycle

b. Boot test: 60℃/4 hours ← Rising and cooling 30 minutes →0℃/6 hours, 2cycle, power supply without packaging and load

Temperature and humidity test:

No power test: 60℃/95%R.H./48 hours

Boot test: 60℃/95%R.H./24 hours/no packaging power supply load

Impact test: impact distance 3m, slope 15 degrees, six sides

Waterproof test: height 30 cm, 10 liters /min spray Angle 60 degrees, spraying position: front and back up, spraying range 1 square meter, spraying time 1 minute

Humidity test: 40℃/90%R.H./8 hours ←→25℃/65%R.H./16 hours, 10cycle)

High and low temperature preservation test: 60℃/95%R.H./72 hours →10℃/72 hours

Continuous switch action test:

Complete the switch within one second, shut down for at least three seconds, 2000 times, 45℃/80%R.H.

Continuous action test: 40℃/85%R.H./72 hours/power on
