7.1.2 Overload Test. Perform in accordance with (IAW) appropriate TM.
7.1.3 Frequency Swing Stability Test.
7.1.3.1 TIER 1 REQUIREMENTS: On 5 KW and greater Generators, perform IAW MIL-STD-
705, Method 608.1, 90% rated resistive load only; except no test recording instrumentation is
required. On 2 KW and 3 KW Generators, perform IAW MIL-STD-705, Method 608.1, 80%
rated resistive load only; except no test recording instrumentation is required. The generator set
shall have the applicable rated resistive load applied IAW Method 608.1 and shall be deemed
acceptable if no generator faults occur during the test.
