Pre-notification for the revision of EMC technical standard to collect public opinions until June 3rd for wireless power transmission devices and microwaves.
This will be effective 3 months later after publishing it.
1. Add radiated emission limit to wireless power transmission device for the home over 10 W power as below:
Frequency(MHz) |
QP limit(dB(uA/m)) at 3 m distance |
0.009 ~ 0.070 |
69 |
0.070 ~ 0.1485 |
69 ~ 39 |
0.1485 ~ 4.0 |
39 ~ 3 |
4.0 ~ 30 |
3 |
Note : The limit below 10 W could be applied to this device over 10 W. |
2. Revise the radiation disturbance weighted limit over 1 GHz for microwave
Frequency range GHz |
Limits for a measuring distance of 3 m Peak dB(uV/m) |
1 - 2.4 |
60 |
2.5 – 5.725 |
60 |
5.875 - 18 |
60 |
Weighted measurements with a resolution bandwidth of 1MHz and video bandwidth of 10 Hz. |
Measure with a span of 10MHz on the spectrum analyzer in below several frequency ranges instead of 2 frequency ranges. The frequency range is as follows:
-1005 ~ 2395 MHz, 2505 ~ 6125MHz (outside 5720 ~ 5880MHz), 6125 ~ 8575 MHz, 8575 ~ 11025MHz, 11025 ~ 13475MHz, 13475 ~ 15925MHz, 15925 ~ 17995MHz
