comply with specified requirements shall receive particular attention for adequacy and suitability.
This element of inspection shall encompass all visual examinations and dimensional measurements
of requirements as listed in table I. Noncompliance with any specified requirement or presence of
one or more defects preventing or lessening maximum efficiency shall constitute cause for
rejection.
4.5 Method of inspection.
4.5.1 Materials. Conformance to 3.2 shall be determined by inspection of contractor

steady idling between 650 to 700 rpm.
4.5.3.2 Governor. To determine conformance to 3.4.4, the engine maximum speed shall
be measured.
4.5.3.3 Dynamometer performance. Torque (see 3.4.5.1) and brake horsepower
(see 3.4.5.2) shall be determined by dynamometer performance, and corrected to standard
conditions. Fuel consumption (see 3.4.5.3) shall be determined from observed bhp and observed
