Roof Strength Test Protocol IIHS
Force and displacement data are recorded for 5 seconds prior to each test, while the test system holds the loading platen at initi al roof contact. The data recorded from 1 to 4 seconds of this hold time are averaged for each channel to produce a measurement offset that is subtracted from the data recorded during the crushing of the roof.
