GB 8702-2014Controlling limits for electromagnetic environment (English PDF)

Foreword

This Standard was formulated so as to implement the "People's Republic of

China Environmental Protection Law", strengthen the electromagnetic

environment management and protect public health.

This Standard is an integrated revision to GB 8702-88 Electromagnetic

radiation protection regulations and GB 9175-88 Environmental health

standards for electromagnetic waves. This Standard referred to the

International Commission on Non-Ionizing Radiation Protection (ICNIRP)

"Guidelines for Exposure to Time-varying Electric Fields, Magnetic Fields and

Electromagnetic Fields (300 GHz and below), 1998", and "IEEE standard of

0~3 kHz electromagnetic field safety level" of the Institute of Electrical and

Electronics Engineers (IEEE). It also considered the practice of

electromagnetic environment protection in China. As long as the limits of this

Standard are met, it encourages the electric field, magnetic field,

electromagnetic field facilities (equipment) owners to follow the precautionary

principle, actively take effective measures and reduce public exposure.

This Standard specifies the field limits, evaluation methods and relevant

facilities (equipment) exemptions of electric field, magnetic field,

electromagnetic field (1Hz ~ 300GHz) of controlling public exposure in the

electromagnetic environment.

This Standard was first issued in 1988.This is the first revision.

The main content of this revision are as follows.

- added the public exposure controlling limits for the electric field and

magnetic field in the 1 Hz to 100 kHz band;

- deleted the occupational exposure limits;

- deleted the administrative content requirements;

- adjusted the monitoring requirements;

- supplemented the scope of the exchange of power transmission

facilities.

Since the implementation of this Standard, GB 8702-88 Electromagnetic

radiation protection regulations and GB 9175-88 Environmental health

standards for electromagnetic waves are repealed simultaneously.

This Standard were proposed by Environmental Protection Department of

Science and Technology Standards Division, Department of Radiation Safety

Supervision Division.

The drafting organization of this Standard. Environmental Protection

Department of Radiation Environmental Monitoring Technology Center.

This Standard was approved on September 8, 2014 by Ministry of

Environmental Protection.

This Standard shall be implemented since January 1, 2015.

This Standard shall be interpreted by Ministry of Environmental Protection.

Controlling limits for electromagnetic environment

1 Scope

This Standard specifies the field limits, evaluation methods and relevant

facilities (equipment) exemptions of electric field, magnetic field,

electromagnetic field (1Hz ~ 300GHz) of controlling public exposure in the

electromagnetic environment.

This Standard is applicable to the evaluation and management of controlling

public exposure in the electromagnetic environment.

This Standard is NOT applicable to the evaluation and management of

controlling patients or escort personnel exposure to treatment or diagnosis; is

NOT applicable to the evaluation and management of controlling exposures

of wireless communication terminal, household appliances to users. It cannot

be used as product quality requirements for facilities (equipment) that

generate electric field, magnetic field, electromagnetic field.
