• Test frequency 14 Once per 31 days 11 Once per 7 days 12** 15

• Criteria for determining number of f ailures and number of valid tests shall be in accordance with Regulatory Position C.2.e of Regulatory Guide 1.108, but determined on a per diesel generator basis.

For the purposes of determining the required test frecuency, the previous test failure count may be reduced to zero if, in conjunction with the manu-f acturer a complete diesel overhaul to like-new conditions is completed, and if acceptable reliability has been demonstrated. The reliability crite-rion shall be the successful completion of 14 consecutive tests in a single series. Ten of these tests shall be in accordance with Surveillance Require-ment 4.8.1.1.2.a.3 and 4.8.1.1.2.a.4; four tests, in accordance with Surveillance Requirement -4.0.11 If this criterion is not satisfied
