  "text": "The efficiency of the 12V motor-generator shall be determined in accordance with ISO 8854:2012, with the following precisions.\nThe manufacturer shall provide evidence to the Secretary of State that the frequency ranges of the 12V motor-generator are the same as or equivalent to those set out in Table 1.\nThe efficiency of the 12V motor-generator shall be determined on the basis of measurements at each of the operating points listed in Table 1.\nThe current intensity of the 12V motor-generator at each operating point shall be half the rated current. For each operating point, the voltage and the output current of the 12V motor-generator shall be kept constant during the measurement, with the voltage at 14,3 V.\nTable 1\nOperating pointi\nHolding time[s]\nRotational frequencyni [min–1]\nFrequency of operating pointshi\n1\n1 200\n1 800\n0,25\n2\n1 200\n3 000\n0,40\n3\n600\n6 000\n0,25\n4\n300\n10 000\n0,10\nThe efficiency of the 12V motor-generator at each operating point i () [%] shall be calculated in accordance with Formula 1.",
