This band is meant as guidance to preclude routine exceedances of the diesel generator manufacturer's design ratings.

Loads in excess of this band for special testing or momentary variations due to changing bus loads shall not invalidate the test.

Failure of a test per Surveillance Requirement 4.8.1.1.2.d.6.b, following performance of Surveillance Requirement 4.8.1.1.2.d.7, does not require that the 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months test of 4.8.1.1.2.d.7 be repeated.
