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.

磁感应强度 magneticinductionstrength

矢量场B,其作用在具有一定速度的带电粒子上的力等于速度与B 矢量积,再与粒子电荷的乘积,其单位为特斯拉(T)。在空气中,磁感应强度等于磁场强度乘以磁导率μ0,即B=μ0H 。
