Maintenance programmes should include an annual longer test proving engine condition up to 110% of full load for not less than 3 hours and ideally 4. During it the safety chain should be tested: operate the overspeed governor, simulate over-temperatures to check alarms and action, and force the fuel rack off to check automatic shutdown; these tests should not be done when only one generator is running (island or parallel). A safety document or sanction for test may be needed for any secondary supply test.
This control maps to 2 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 2 it maps to, and the evidence behind each claim, over MCP and REST.
