- 3. All other clubs not covered by 1. and 2. (except putters) will be evaluated for spring effect solely using the Pendulum Test ¹. Clubs which have a maximum characteristic time (CT) within the impact area², in excess of 239 microseconds (plus an 18 microsecond tolerance) will be ruled non-conforming. Clubs which have a maximum characteristic time outside the impact area for a club in excess of 257 microseconds (plus an 18 microsecond tolerance) will be ruled non-conforming. · usga.org
