Unit Compliance—Operate the properly commissioned knock test unit at temperature equilibrium and in compliance with the basic engine and instrument settings and standard operating conditions prescribed for this test method.
12.1.1  Operate the engine on fuel for approximately 1 h to ensure that all critical variables are stable.

equilibrium fuel level, n—for knock testing, test procedure in which the fuel-air ratio for maximum knock intensity for sample and reference fuels is determined by making incremental step changes in fuel-air ratio, observing the equilibrium knock intensity for each step, and selecting the level which produces the highest knock intensity reading.
