5.3.2 Normal test power source
5.3.2.1 Mains voltage
The normal test voltage for equipment to be connected to the mains shall be the nominal mains voltage. For the purpose of the present document, the nominal voltage shall be the declared voltage, or any of the declared voltages, for which the equipment was designed.
The frequency of the test power source corresponding to the ac mains shall be between 49 Hz and 51 Hz.
5.3.2.2 Regulated lead-acid battery power sources
When the radio equipment is intended for operation with the usual types of regulated lead-acid battery power source,the normal test voltage shall be 1,1 multiplied by the nominal voltage of the battery (e.g. 6 V, 12 V, etc.).
5.3.2.3 Other power sources
For operation from other power sources or types of battery (primary or secondary), the normal test voltage shall be that declared by the equipment provider and agreed by the accredited test laboratory. Such values shall be stated in the test report.
