BS EN 50413:2008+A1:2013

This standard BS EN 50413:2008+A1:2013 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:

• 13.280 Radiation protection
• 17.220.20 Measurement of electrical and magnetic quantities
• 33.100.01 Electromagnetic compatibility in general

This European Standard gives elements to establish methods for measurement and calculation of quantities associated with the assessment of human exposure to electric, magnetic and electromagnetic fields (EMF) in the frequency range from 0 Hz to 300 GHz. The major intention of this Basic Standard is to give the common background and information to relevant EMF standards. This Basic Standard cannot go into details extensively due to the broad frequency range and the huge amount of possible applications. Therefore it is not possible to specify detailed calculation or measurement procedures in this Basic Standard. This standard provides general procedures only for those product and workplace categories for which there do not exist any relevant assessment procedures in any existing European EMF basic standard. If there exists an applicable European EMF standard focused on specific product or workplace categories then the assessment shall follow that standard. If an applicable European EMF standard does not exist, but an applicable assessment procedure in another European EMF standard does exist, then that assessment procedure shall be used.

This standard deals with quantities that can be measured or calculated in free space, notably electric and magnetic field strength or power density, and includes the measurement and calculation of quantities inside the body that forms the basis for protection guidelines.

In particular the standard provides information on

• definitions and terminology,

• characteristics of electric, magnetic and electromagnetic fields,

• measurement of exposure quantities,

• instrumentation requirements,

• methods of calibration,

• measurement techniques and procedures for evaluating exposure,

• calculation methods for exposure assessment.
