Hello vivek1,

The attached document describes crash test criteria and filter methods. The filter requirement  is based on what kind of sensor/body part you are looking at. For head acceleration data, the filter is a CFC1000, other body parts have other filter requirements. The requirements are laid layout in the FMVSSS and SAE documents listed in the attached file.

Hope this helps,
