# What is the EMF limit in China?

> GB 8702-2014 allows 0.4 W/m² (12 V/m) below 3 GHz, f/7500 W/m² from 3–15 GHz, and 100 µT / 4 kV/m at 50 Hz — for environmental exposure, not your own devices.

## Question

What public exposure limits does China's GB 8702-2014 set?

## Answer

GB 8702-2014 caps public exposure at 12 V/m (0.4 W/m²) from 30 MHz to 3000 MHz, f/7500 W/m² from 3 to 15 GHz — 0.47 W/m² at 3.5 GHz — and 27 V/m (2 W/m²) from 15 to 300 GHz, all as RMS values over any continuous six minutes. At power frequency the limits are 100 µT and 4 kV/m, with 10 kV/m permitted on farmland and roads under overhead transmission lines. The standard governs environmental exposure from installations; it explicitly does not regulate what your own phone or household appliances expose you to.
