Experimental models and weighting factors.

Test cycle type	Rotational speed (%)	Power (%)	Weighting factor
E2 experimental cycle for the “constant speed main propeller” application (including diesel electric drive and all adjustable pitch propeller units)	100	100	0.2
	100	75	0.5
	100	50	0.15
	100	25	0.15
E3 experimental cycle for “main and auxiliary engines operating according to propeller law” application	100	100	0.2
	91	75	0.5
	80	50	0.15
	63	25	0.15
