General Information
Relations
Overview
EN 50413:2019/A1:2025 is the CLC basic standard that specifies general measurement and calculation procedures for assessing human exposure to electric, magnetic and electromagnetic fields in the frequency range 0 Hz–300 GHz. It is tailored for: product emission assessment against public exposure limits in Council Recommendation 1999/519/EC and worker exposure requirements in Directive 2013/35/EU, and for workplace exposure evaluations to determine compliance with Directive 2013/35/EU.
The document addresses quantities measurable external to the body (e.g., electric and magnetic field strength, power density) and also discusses calculation of internal quantities that underpin protection guidance. Where a product- or technology-specific EMF standard exists, that standard should be used in preference to EN 50413.
Key Topics
- Definitions and terminology relevant to exposure assessment and EMF measurement.
- Characteristics of electromagnetic fields across a wide frequency band (0 Hz–300 GHz).
- Measurement of exposure quantities including field strength and power density.
- Instrumentation requirements and methods of calibration to ensure traceable, repeatable results.
- Measurement techniques and procedures for evaluating exposure around products and installations.
- Calculation methods for scenarios where direct measurement is impractical.
- Consideration of signal modulation (new Annex B): guidance on modulation effects, classification of emissions (ITU Radio Regulations), and conversion relationships between carrier power, mean power and peak power for common modulation types.
The amendment adds explicit guidance on how modulation and duty cycle can influence measurement and compliance verification, and includes informative Annex B with classification and conversion tables (e.g., Table B.2) for converting between carrier, mean and peak power notations where necessary.
Applications
EN 50413:2019/A1:2025 is practical for:
- Product manufacturers performing emission testing and preparing conformity evidence against EU exposure limits.
- Test laboratories defining measurement procedures, instrumentation and calibration routines.
- Employers and safety professionals conducting workplace exposure assessments to demonstrate compliance with Directive 2013/35/EU.
- Regulatory authorities and site operators evaluating transmitter characteristics (carrier/mean/peak power, antenna gain/directionality) to support exposure assessments.
Benefits include consistent assessment practices, clearer handling of modulated signals in exposure evaluations, and improved comparability of measured and calculated exposure metrics.
Related Standards
- Council Recommendation 1999/519/EC (public exposure reference levels)
- Directive 2013/35/EU (worker exposure action levels and requirements)
- EN 62311 and other product- or technology-specific EMF standards (see reference list in EN 50413)
- ITU Radio Regulations (classification of emissions and terms used in Annex B)
Practical note: consult any applicable specific standard for the product or technology first; use EN 50413 where no product-specific standard exists or for general measurement and calculation guidance across the 0 Hz–300 GHz range.

34 The Radio Regulations, drawn up by the International Telecommunication Union (ITU), classify the emissions
35 from radio-transmitters according to the required bandwidths, and the basic and optional characteristics of the
36 transmission [B1]. The complete classification consists of nine characters as follows:
37 • Characters 1 – 4 describe the bandwidth, using three digits and one letter;
38 • Characters 5 – 7 describe the basic characteristics, using two letters and one digit;
39 • Characters 8 – 9 describe any optional characteristics, using two letters.
40 In the given context the three basic characteristics are relevant, i.e.:
• type of modulation of the main carrier Character 5;
• nature of the signal(s) which modulate(s) the main carrier Character 6;
• type of information to be transmitted Character 7.
41 Information about the transmitter power supplied to the antenna, the type of modulation, and the gain and
42 directional characteristics of the antenna can be obtained from the transmission authority which is responsible
43 for operating the equipment at a particular site. It is important to know whether the transmitter power is
