Each product undergoes a series of technical tests and quality inspections before shipment to ensure product quality.
 
Water-Proof Test
Perform IPX4 water proof rating standard,put the poles in the car,dripping for 10minutes, flushing for many times.
 
Salt Spray Test
Place the poles in 5% Nacl solution of salt spray for 256 hours. Then washing the solution with flowing water, rinsing with distilled water, and putting after 1-2 hours. Check if the pole is rust.
 
High Temperature Test
Verify if the product function is normal before tests. Storage temperature +90℃,humidity 30%-90%, then placing the poles in the test chamber for 8 hours. When the test is completed, poles can be freely stretched. Verify if the product function is normal before tests. Then the pole is powered up normally, in the same environment (operating temperature:+90℃, humidity:40%-90%), putting the poles in the test chamber for 8 hours. Check if the poles can be freely stretched and the the function is normal.
 
Low Temperature Test
Verify if the product function is normal before tests. The pole is powered up normally. Then putting the poles in -40℃ test chamber for 8 hours. Check the poles can be freely stretched and the the function is normal.
 
High and Low Temperature Cycle Test
Verify if the product function is normal before tests. The pole is powered up normally. Then putting the poles in -30 ℃ test chamber for 12 hours. Temperature is from -30℃ up to +85℃, and temperature change time is half an hour. Continuously putting for 12 hour. After 12 hours, changing temperature from +85℃ decline to -30℃. Temperature change time is  half an hour. This is one cycle, cycle 10 times. A total of 240 hours. Check if the poles can be freely stretched and the the function is normal.
