What is the EMF limit in China?

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.

  China's mandatory national standard for public exposure from 1 Hz to 300 GHz, referencing ICNIRP 1998 and IEEE but setting values of its own that are stricter in the mobile bands.

  Standards & frameworks

• China public limit, 30–3000 MHz

  12 V/m, equivalently 0.4 W/m², across the FM, TV, and sub-3 GHz cellular and Wi-Fi bands — the strictest widely enforced national limit in that range apart from Russia's.

  Exposure limits

• China public limit at 50 Hz (power frequency)

  100 µT magnetic flux density and 4 kV/m electric field for public exposure at 50 Hz, with 10 kV/m allowed on farmland and roads beneath overhead transmission lines.
