5. Vibration Test
6. Sealing Test (A Sealed Unit is not required to meet the requirements of Dust Test, Corrosion Test and Humidity Test)

Today, we would like to talk more detail about FMVSS 108 Temperature Cycle Test and Environmental Test Based on the following Figure.

Temperature Cycle Test：10 complete consecutive cycles having the thermal cycle.

Environmental Test ：

Its testing method includes Testing Temperature：-32⁰C to 63⁰C；

Testing Time：60 hours continuous tests as below photo.
