![]() Receiver: a measurement instrument capable of doing Quasi-Peak (QP) and Average (AV) measurements.Ĭurrent probe: to transform the measured current into a voltage signal to be read by the receiver. Shielded enclosure: it is not compulsory to execute conducted emissions tests within a shielded chamber, but it is required that the ambient electromagnetic noise levels are, at least, 6 dB below the limits specified in the planned test. The distance between the center of the wiring harness and the antenna must be 1000 mm ± 10 mm.įrequency range: from 105 kHz to 108 MHz, to be sure that commercial radio frequencies are not disturbed by the system. If the EUT has a power return line locally grounded, only one LISN is required, for the positive supply line. If the EUT has a power return line remotely grounded, one LISN is installed for the positive supply line and one for the power return line. The EUT shall be wired as it will be in the vehicle. These conditions must be defined in the test plan to guarantee test repeatability. ![]() The EUT shall operate under typical loading such as the maximum emission state occurs. ![]() The wiring harness shall be supported 50 mm above the ground plane by a non-conductive material and arranged in a straight line. Vehicles with a traction battery voltage 1000 V.Įlectric and hybrid road vehicles with a sustainable speed ≤ 6 km/hĪn EMI receiver with Peak (PK), Quasi-peak (QP), or average (AV) detector, as defined in the CISPR 16-1-1 standard.Ī Line Impedance Stabilization Network (LISN), also known as Artificial Mains Network (AMN), Artificial Network (AN), or V-Network.ĭifferent types of antennas: a monopole rod antenna, a biconical one, or a double-ridge guide horn.Īn Absorber-Line Shielded Environment (ALSE). Vehicles where the electric motor is used for additional propulsion only during acceleration (mild hybrid vehicles). Vehicles where the electric motor is only used to start up the internal combustion engine (micro hybrids). The following vehicles are excluded:Įlectric vehicles to which CISPR-14-1 applies. SAE J551-4 and SAE J1113-41 are equivalent to CISPR 25.ĬISPR 36 defines limits and methods of measurement to provide protection for off-board receivers from emissions by electric and hybrid electric vehicles propelled by an internal traction battery when operated on the road and over the frequency range from 150 kHz to 30 MHz. The limits are intended to provide protection for on-board receivers installed (per the manufacturer’s guidelines) in a vehicle from disturbances produced by components/modules in the same vehicle. It is frequently used as a base standard for other ones. This standard is intended to protect receivers from disturbances produced by conducted and radiated emissions arising in a vehicle in the frequency range from 150 kHz to 5925 MHz. SAE J551-2 is equivalent to CISPR 12.ĬISPR 25 is applicable to vehicles, boats, and internal combustion engines with a speed of more than 6 km/h. It gathers EMC requirements for components and vehicles to be type-approved.ĬISPR 12 is applicable to vehicles and boats propelled by an internal combustion engine, electrical means, or both and it specifies the limits and methods of radiated emission measurements to protect off-board receivers from 30 MHz to 1000 MHz. UNECE R10 is a regulation of the Economic Commission for Europe of the United Nations (UNECE).
