(a) Car and counterweight buffers shall be provided and shall conform to the applicable requirements of Section 3031.

(b) For rack and pinion elevators, spring buffers, where used, shall be so designed and installed that they will not be fully compressed when struck by the car with its rated load at governor tripping speed where the safety is governor operated, or at 125% of rated speed where the safety is not governor operated. Kinetic energy from the drive unit shall be taken into account in the design calculations. The effect of the counterweight, where used, may also be taken into account in the design calculations.
