37、nt document shall be as follows: the measured value related to the corresponding limit shall be used to decide whether an equipment meets the requirements of the present document; the measurement uncertainty value for the measurement of each parameter shall be separately included in the test report;

38、 the recorded value of the measurement uncertainly shall be, for each measurement, equal to or lower than the figures in the table of measurement uncertainty in clause 1 O. 5 Test conditions, power sources and ambient tem perat u res 5.1 Normal and extreme test conditions Type testing shall be made

39、under normal test conditions, and also, where stated, under extreme test conditions. The test conditions and procedures shall be as specified in clauses 5.2 to 5.4. 5.2 External test power source During type tests, the power source of the equipment shall be replaced by an external test power source

40、capable of producing normal and extreme test voltages as specified in clauses 5.3.2 and 5.4.2. The internal impedance of the external test power source shall be low enough for its effect on the test results to be negligible. For the purpose of the tests, the voltage of the external test power source

41、 shall be measured at the input terminals of the equipment. The non-grounded terminal of the batteries shall be disconnected, but batteries shall be left in place. The external test power source shall be suitably de-coupled and applied as close to the equipment battery terminals as practicable. The

42、power leads shall be as short as practicable and properly dressed. For radiated measurements fully charged internal batteries should be used. The batteries used should be as supplied or recommended by the applicant. During tests the external test power source voltages shall be within a tolerance *1

43、% relative to the voltage at the beginning of each test.

In the case of equipment containing temperature stabilization circuits designed to operate continuously, the temperature stabilization circuits shall be switched on for 15 minutes after thermal balance has been obtained, and the equipment shall then meet the specified requirements. If the ther

48、mal balance is not checked by measurements, a temperatwe stabilizing period of at least one hour, or such period as may be decided by the accredited test laboratory, shall be allowed. The sequence of measurements shall be chosen, and the humidity content in the test chamber shall be controlled so th
