Measurement Methods for Electromagnetic Fields of Vehicle With Regard To Human Exposure
1 SCOPE
This Standard specifies the methods for measuring the emissions from low-frequency magnetic fields of the vehicle to which the human body is exposed.
The frequency range covered by this Standard is 10Hz to 400 kHz.
This Standard applies to the vehicles of categories L, M and N.
This Standard doesn’t apply to the measurement of wireless charging state for vehicles.

3.1
Magnetic induction strength
「Magnetic induction strength」 means a vector field quantity, B, of which the force acting on a charged particle with a certain speed is equal to the vector product of 「speed」 and 「B」, multiplied by the particle charge, and is expressed in T. In the air, the magnetic induction strength equals to the magnetic field strength multiplied by the permeability μ0, i.e. B= μ0H.

磁感應強度 magneticinductionstrength
矢量場B,其作用在具有一定速度的帶電粒子上的力等於速度與B 矢量積,再與粒子電荷的乘積,其單位為特斯拉(T)。在空氣中,磁感應強度等於磁場強度乘以磁導率μ0,即B=μ0H 。
