CERTIFIED POWER RATING
ENGINE RATINGS BASELINES
• Each engine is factory tested to verify power and performance.
• Engines are to be used for stationary emergency standby fire pump service only. Engines
are to be tested in accordance with NFPA 25.
• Engines are rated at standard SAE conditions of 29.61 in. (752.1 mm) Hg barometer and
77°F (25°C) inlet air temperature [approximates 300 ft. (91.4 m) above sea level] by the
testing laboratory (see SAE Standard J 1349).
1349)
• A deduction of 3 percent from engine horsepower rating at standard SAE conditions shall
be made for diesel engines for each 1000 ft. (305 m) altitude above 300 ft. (91.4 m)
FM
• A deduction of 1 percent from engine horsepower rating as corrected to standard SAE
conditions shall be made for diesel engines for every 10°F (5.6°C) above 77°F (25°C)
ambient temperature.

3Engine has dual exhaust outlets. Combined total exhaust flow from both outlets is given. 4Based on Nominal System. Back pressure flow
analysis must be done to assure maximum allowable back pressure is not exceeded. (Note: minimum exhaust Pipe diameter is based on: 15 feet of
pipe, one 90° elbow, and a silencer pressure drop no greater than one half of the maximum allowable back pressure.) 5Review for horsepower
