RATING CONDITIONSRatings are based on SAE J1228/ISO8665standard conditions of 100 kPa (29.61 in. Hg),25C (77F), and 30% relative humidity. Theseratings also apply at ISO3046/1, DIN6271/3, andBS5514 conditions of 100 kPa (29.61 in. Hg),27C (81F), and 60% relative humidity.

Fuel rates are based on fuel oil of 35 API[16C (60F)] gravity having an LHV of 42 780 kJ/kg (18,390 Btu/lb) when used at 29C(85F) and weighing 838.9 g/L (7.001 lb/U.S. gal).

Additional ratings may be available for specificcustomer requirements. Consult your Caterpillarrepresentative for additional information.
