7.1 Winches
Winch brakes shall be of robust construction and afford complete control and limitation of speed in the operation and lowering.

The mass of the brake lever shall be sufficient to operate the brake effectively without additional pressure. The winch brakes of a launching appliance shall be of sufficient strength to withstand:
7.1.1 a static load test with a proof load of not less than 1.5 times the maximum work load; and
7.1.2 a dynamic test with a proof load of not less than 1.1 times the maximum working load at the maximum lowering speed.
