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)|
