#
identification plate (see 3.11.1) shall be the engine full-power output if specified in the
applicable contract. In cases where the contract does not specify engine full-power output,
but does specify full-rated capacity of the driven equipment, the engine identification
plate shall indicate the actual engine power required to drive the driven equipment at it's
contract rated capacity. If no hp output equipment is indicated in the contract, the engine
identification plate hp should be the hp value chosen as the "rated-load" during performance
of the endurance phase of the first article endurance test (see 4.4.2.2) . In no case can
the engine identification plate hp be greater than this rated (full) load figure of 4.4.2.2.
