1 Scope
This document provides general methods for measurement and calculation of quantities associated with human
exposure to electromagnetic fields in the frequency range from 0 Hz to 300 GHz. It is intended specifically to be used
for the assessment of emissions from products and comparison of these with the exposure limits for the general public
given in Council Recommendation 1999/519/EC, and those given for workers in Directive 2013/35/EU, as appropriate.
It also is intended to be used for assessment of human exposure to electromagnetic fields in the workplace to
determine compliance with the requirements of Directive 2013/35/EU.
This standard deals with quantities that can be measured or calculated external to the body, notably electric and
magnetic field strength or power density, and includes the measurement and calculation of quantities inside the body
that form the basis for protection guidelines. In particular the standard provides information on:
— definitions and terminology,
— characteristics of electromagnetic fields,
— measurement of exposure quantities,
— instrumentation requirements,
— methods of calibration,
— measurement techniques and procedures for evaluating exposure,
— calculation methods for exposure assessment.
Where an applicable electromagnetic field standard specific to a product or technology exists it is expected to be used
rather than this document. EN 62311:—, Table 1 gives a list of relevant standards.
