Generic standard for assessment of low power electronic and electrical equipment related to human exposure restrictions for electromagnetic fields (10 MHz - 300 GHz)
This European standard provides simple conformity assessment methods for low-power electronic and electrical equipment operating at frequencies between 10 MHz and 300 GHz to an electromagnetic field (EMF) exposure limit. If such equipment cannot be shown to comply with the applicable EMF exposure requirements using the exposure assessment methods in this standard, then other EMF product standards may be used for conformity assessment. Other standards can apply to products covered by this document. In particular this document is not designed to evaluate the electromagnetic compatibility with other equipment; nor does it reflect any product safety requirements other than those specifically related to human exposure to electromagnetic fields.
Fachgrundnorm für die Beurteilung der Übereinstimmung von elektronischen und elektrischen Geräten kleiner Leistung mit den Basisgrenzwerten für die Exposition von Personen gegenüber elektromagnetischen Feldern (10 MHz bis 300 GHz)
Norme générique pour l'évaluation des appareils électriques et électroniques de faible puissance concernant les restrictions en matière d'exposition du corps humain aux champs électromagnétiques (10 MHz à 300 GHz)
La présente Norme européenne fournit des méthodes simples pour l’évaluation de la conformité des appareils électriques et électroniques de faible puissance fonctionnant à des fréquences comprises entre 10 MHz et 300 GHz, à une limite d’exposition aux champs électromagnétiques (EMF, electromagnetic field). S'il ne peut pas être démontré, en utilisant les méthodes d’évaluation de l'exposition de la présente norme, qu’un appareil satisfait aux exigences d'exposition aux champs électromagnétiques applicables, d'autres normes de produit sur les champs électromagnétiques peuvent alors être utilisées pour l'évaluation de la conformité. Le présent document a été élaboré dans le cadre d'un mandat donné au CENELEC par la Commission européenne et l’Association européenne de libre-échange, et vient à l'appui des exigences essentielles de la Directive sur les équipements radioélectriques 2014/53/UE. L'Annexe ZZ établit des relations entre la présente norme et cette Directive UE. D'autres normes peuvent s'appliquer aux produits couverts par le présent document. En particulier, ce document n'est pas destiné à évaluer la compatibilité électromagnétique avec d'autres appareils; par ailleurs, il ne reflète pas les exigences de sécurité du produit autres que celles liées spécifiquement à l'exposition des personnes aux champs électromagnétiques.
Splošni standard za oceno skladnosti nizkonapetostne elektronske in električne opreme glede na mejne vrednosti izpostavljenosti ljudi elektromagnetnemu sevanju (10 MHz - 300 GHz)
Ta evropski standard določa preproste metode za ocenjevanje skladnosti za nizkonapetostno elektronsko in električno opremo, ki deluje pri frekvencah med 10 MHz in 300 GHz glede na mejne vrednosti izpostavljenosti elektromagnetnemu sevanju (EMF). Če skladnosti take opreme z veljavnimi zahtevami glede izpostavljenosti elektromagnetnemu sevanju ni mogoče prikazati z metodami za ocenjevanje v tem standardu, se lahko za oceno skladnosti uporabijo drugi standardi za proizvode elektromagnetnega sevanja.
Ta dokument je bil pripravljen v okviru mandata, ki sta ga CENELEC dodelila Evropska komisija in Evropsko združenje za prosto trgovino, ter podpira bistvene zahteve Direktive o radijski opremi EU 2014/53/EU. Dodatek ZZ navaja razmerja med tem standardom in tistimi evropskimi direktivami.
Za proizvode, ki jih obravnava ta dokument, se lahko uporabljajo drugi standardi. Ta standard ni namenjen za ocenjevanje elektromagnetne združljivosti z drugo opremo in ne odraža nobenih varnostnih zahtev za proizvode, razen tistih, ki se posebej navezujejo na izpostavljenost delavcev elektromagnetnemu sevanju.

Overview
EN 50663:2017 (CENELEC) is a European, harmonised product standard that defines simple conformity assessment methods for low‑power electronic and electrical equipment with respect to human exposure limits to electromagnetic fields (EMF) in the 10 MHz to 300 GHz range. It supports conformity assessment for the Radio Equipment Directive (2014/53/EU) and the Low Voltage Directive (2014/35/EU) where EMF exposure is the relevant safety objective. This standard is intended to be read alongside EN 62479:2010 and EN 62311:2008.
Key topics and requirements
- Scope: Applies to low‑power equipment operating between 10 MHz and 300 GHz; focuses solely on human EMF exposure limits, not on electromagnetic compatibility (EMC) or unrelated product safety requirements.
- Exposure conditions: Requires assessment of all reasonably foreseeable operating and human‑exposure conditions, including time‑averaging and multi‑band operation. Equipment intended only for worker use must be clearly identified.
- Normative limits:
- For the general public, basic restrictions follow Table 1 of Annex II of Council Recommendation 1999/519/EC.
- For workers, exposure limit values follow Annex III (Tables A1–A3) of Directive 2013/35/EU.
- Conformity assessment methods: Evaluation procedures reference EN 62479:2010 (routes and Pmax replacement values) and reporting as per EN 62311:2008.
- Pmax values (assessment tiers):
- General public - head & trunk: 20 mW; limbs: 40 mW
- Workers - head & trunk: 100 mW; limbs: 200 mW
- Uncertainty and reporting: Assessment uncertainty shall be calculated according to EN 62479; evaluation reports follow EN 62311 requirements.
- Limitations: If a device cannot be shown compliant using EN 50663 methods, other EMF product standards must be used. This standard does not assess EMC with other equipment.
Applications and who uses it
EN 50663 is practical for:
- Manufacturers and design teams of low‑power radio and electronic devices seeking a streamlined route to demonstrate EMF safety.
- Compliance engineers and regulatory affairs specialists preparing technical files for CE marking under the Radio Equipment and Low Voltage Directives.
- Test laboratories and notified bodies performing product EMF exposure assessments and preparing conformity reports.
- Product managers evaluating design trade‑offs to meet public vs worker exposure limits.
Typical use cases include compliance assessment of consumer wireless devices, IoT modules, wearables and other low‑power transmitters where human exposure assessment is required.
