LED light test - Simulated vibration test     

          
With gradual improvement of LED testing standards, The transportation safety testing of flood light is also a very important indicator. To protect flood lights’ safety in transportation environment, our company has introduced a simulated transport vibration table for testing the actual transport security.

 
ISTA standard US transport association standard ASTM standard US  material association standard ) two standard to simulate the transport vibration equipment requirements :
 
The amplitude of 25.4 mm (1 inch, fixed), frequency of 1.5-5 hz (or 100-300 RPM adjustable), the experimental basis for: T = 14200 / CPM (based on the total vibration frequency of 14200 times), test speed option:
 
 
ISTA/ASTM standard test method :
 

test speed(CPM) corresponding frequency(Hz) test time(M)
150 2.5 95
180 3.0 79
210 3.5 66
240 4.0 60
270 4.5 53
300 5.0 48
