本标准适用于非通信用汽车对无线电接收造成干扰的电磁辐射允许值和测量方法。1 允许值以准峰值型测量仪测量的辐射允许值:对于40—75MHz的频段恒定为34dB;对于75~250MHz的频段为34~42dB,在此频段内允许值随频率线性增大(见图1)。 This standard applies to non-communications vehicles on the radio interference caused by electromagnetic radiation allowable values ​​and measurement methods. 1 Allowable value The allowable value of the radiation measured by a quasi-peak type meter: constant for the band of 40-75 MHz to 34 dB; for the band from 75 to 250 MHz, from 34 to 42 dB, the allowable value increases linearly with frequency in this band (see figure 1).
