1 Scope This standard specifies the measurement methods for low-frequency magnetic field emission in the vehicle environment exposed to by human beings. This standard is applicable to the frequency range of 10 Hz to 400 kHz. This standard is applicable to Categories L, M and N vehicles. This standard is not applicable to measurement of vehicles under wireless charging state. 2 Normative references The following referenced documents are indispensable for the application of this document.

The magnetic induction strength is equal to the product of magnetic field strength multiplied by magnetic permeability μ0 in air, i.e. B=μ0H. [Definition 3.8 in GB 8702-2014] 3.2 general public exposure all electric, magnetic and electromagnetic fields exposure borne by public, excluding occupational exposure and medical exposure 3.3 internal combustion engine machine that converts chemical energy from fuel combustion into thermal energy and then into mechanical energy inside the engine cylinder. 3.4 internal combustion engine vehicle; ICEV vehicle powered entirely by an internal combustion engine. 3.5 idling state of engine running without load. That is, the clutch is in the engaged position and the gearbox is in the neutral position (the vehicle with automatic gearbox in the "parking" or "P" position); for the vehicle with the carburetor fueling system, the choke valve is in the fully open position; the accelerator pedal is in the fully released position. 3.6 standby state of drive motor system being powered at high voltage while not running.
