(2) The maximum calculated HIC36 value shall not exceed 1,000.

(b)

(1) For any two points in time, t1 and t2, during the event which are separated by not more than a 15 millisecond time interval and where t1 is less than t2, the head injury criterion (HIC15) shall be determined using the resultant head acceleration at the center of gravity of the dummy head, ar, expressed as a multiple of g (the acceleration of gravity) and shall be calculated using the expression:

(2) The maximum calculated HIC15 value shall not exceed 700.
