BS EN 50413:2019+A1:2025

This standard BS EN 50413:2019+A1:2025 Basic standard on measurement and calculation procedures for human exposure to electric, magnetic and electromagnetic fields (0 Hz - 300 GHz) is classified in these ICS categories:

• 17.220.20 Measurement of electrical and magnetic quantities
• 13.280 Radiation protection
• 33.100.01 Electromagnetic compatibility in general
• 17.200.20 Temperature-measuring instruments

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.
