Overview
EN 61000-3-3:2013/A1:2019 is a CENELEC-adopted amendment to IEC 61000-3-3 addressing electromagnetic compatibility (EMC) limits for voltage changes, voltage fluctuations and flicker in public low-voltage supply systems. The standard applies to equipment with a rated current ≤ 16 A per phase and not subject to conditional connection. Amendment A1 was approved by CENELEC (parallel to IEC) and published in 2019; users should note implementation dates and any temporary holds on citation in the Official Journal.
This standard provides normative limits, test conditions and measurement procedures to evaluate equipment behaviour that can affect mains voltage quality and perceptible lighting flicker.
Key Topics
- Scope: Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems for equipment rated ≤ 16 A per phase.
- Limits and behaviour: Amendment A1 refines Clause 5 to clarify how limits apply for equipment with multiple separately controlled circuits, and differentiates automatic restart behaviour from manual switching.
- Specific test provisions:
- Hotplates: area cooking plates that configure zones from multiple small hotplates are tested with the biggest saucepan from the referenced table placed at the geometric centre.
- Lighting: P and P evaluations are required only for lighting equipment likely to produce multiple voltage fluctuations (for example due to fast varying internal loads). Incandescent luminaires ≤ 1000 W and discharge/LED luminaires ≤ 600 W are deemed to comply with the d, d and T limits and may be exempt from testing.
- Annex B: Test conditions and procedures for measuring voltage changes caused by manual switching; procedure may also be used to measure d and T parameters.
- Regulatory relationship: Informative Annexes ZZA and ZZB show correspondence with Directive 2014/30/EU (EMC Directive) and Directive 2014/53/EU (Radio Equipment Directive). When cited in the Official Journal, compliance with the normative clauses confers a presumption of conformity within scope.
Applications
EN 61000-3-3:2013/A1:2019 is used by:
- Manufacturers of household and similar electrical equipment rated ≤ 16 A per phase to design for mains compatibility and reduce flicker impact on lighting.
- Test laboratories performing flicker and voltage-fluctuation measurements.
- Compliance teams preparing technical documentation for CE marking where the standard is cited as a harmonised standard.
Key benefits include reduced perceptible flicker, improved interoperability with public low-voltage networks, and clearer test arrangements for modern appliances (e.g., multi-zone cooktops and LED luminaires).

SIST EN 61000-3-3:2014/A1:2019 표준은 전자기 호환성(EMC)에 관한 중요한 문서로, 공공 저전압 공급 시스템에서의 전압 변화, 전압 변동 및 깜박임에 대한 한계를 설정합니다. 이 표준의 적용 범위는 정격 전류가 상당하여 16 A 이하인 전기 및 전자 장비에 해당하며, 50 Hz의 전압에서 220 V에서 250 V 사이의 저전압 배급 시스템에 연결될 수 있는 장비를 포함합니다. 이 표준의 강점 중 하나는 전압 변화와 변동을 제한하여 공공 전력 시스템의 안정성을 유지하는 데 기여한다는 점입니다. 또한, 장비가 지정된 조건에서 테스트되었을 때 발생할 수 있는 전압 변화의 한계를 명확히 정의하고 있으므로, 관련 기업들이 이를 준수하여 안전하고 신뢰성 있는 제품을 시장에 공급할 수 있도록 합니다. 또한, SIST EN 61000-3-3은 테스트 방법에 대한 지침을 제공하여 표준을 준수하기 위한 평가 방법을 명확히 하고 있습니다. 이를 통해 기업들은 장비의 전자기 호환성을 평가하여 필요시 IEC 61000-3-11에 따라 재시험하거나 평가할 수 있는 정보를 확보할 수 있습니다. 이 문서는 특정 테스트 조건을 명시하고 있으며, 테스트 회로도 함께 제공하여 실무자들이 실용적으로 적용할 수 있도록 지원합니다. 그래서 전자기 호환성을 요구하는 다양한 산업 분야에서 이 표준의 실효성과 적절성이 더욱 빛을 발합니다.
SIST EN 61000-3-3:2014/A1:2019は、電磁両立性（EMC）に関する重要な基準であり、公共の低電圧供給システムにおける電圧変動やフリッカの制限を規定しています。この標準は、特定の条件下で試験された機器によって発生する可能性のある電圧変化の限界を明確に定義し、その評価方法に関する指針を提供しています。 この標準の範囲は、入力電流が1相あたり16A以下の電気および電子機器に適用され、主に220Vから250Vの範囲内の公共低電圧配電システムに接続されることを目的としています。条件付きの接続に該当しない機器がこの規格の限界を満たさない場合、IEC 61000-3-11に準拠して再試験や評価を行うことができる点も、標準の柔軟性を示しています。このように、SIST EN 61000-3-3は限界と条件を明確にし、技術者や製造者が遵守すべき基準としての役割を果たしています。 さらに、特定の試験条件が附属書Aに記載され、試験回路が図1で示されていることで、実施する際の具体性が確保されています。このような詳細な指針は、実際の試験環境での適用を容易にし、機器の評価や改良をサポートします。 SIST EN 61000-3-3:2014/A1:2019は、電磁両立性の確保を重視する現代の電気機器にとって不可欠な基準であり、公衆の安全と機器の信頼性を保障する重要な文書であるといえるでしょう。
The SIST EN 61000-3-3:2014/A1:2019 standard focuses on electromagnetic compatibility (EMC), particularly addressing limits for voltage changes, voltage fluctuations, and flicker in public low-voltage supply systems for electrical equipment with a rated current of 16 A per phase or less. This standard is crucial for ensuring that devices connected to public low-voltage distribution systems, typically operating at 220 V to 250 V and 50 Hz, do not adversely affect the quality of power supply. One of the significant strengths of this standard is its comprehensive definition of the limits of voltage changes. It offers clear guidelines on the maximum allowable fluctuations that can be safely introduced by electrical equipment, which is vital for maintaining the overall stability and reliability of the public power grid. By specifying these limitations, the standard helps prevent disturbances that can lead to flicker, which is not only a nuisance but can also affect the operation of sensitive electronic devices. The structured approach in the standard, including the provision of specific test conditions detailed in Annex A and the accompanying test circuit diagram in Figure 1, enhances its usability. This clarity ensures that manufacturers can accurately assess their equipment against the standard's requirements. The mention of reference impedance (Zref) of 6.4 for testing further strengthens the accuracy and consistency of compliance testing. Moreover, the standard’s relevance is particularly pronounced in today’s context where the proliferation of electronic devices in homes and businesses necessitates stringent measures to ensure EMC. Equipment that does not meet the laid-out voltage fluctuation limits faces the challenge of being unable to declare compliance with this part, compelling a thorough evaluation under IEC 61000-3-11 for conditional connection scenarios. This tiered approach allows for flexibility in compliance testing while still upholding essential EMC standards. In summary, SIST EN 61000-3-3:2014/A1:2019 stands as a robust framework that not only delineates acceptable limits for voltage changes and flicker but also provides essential guidance for testing. Its detailed conditions facilitate compliance while safeguarding the integrity of public low-voltage supply systems, marking it as a significant standard in the domain of electromagnetic compatibility.
La norme SIST EN 61000-3-3:2014/A1:2019 se concentre sur la compatibilité électromagnétique (CEM), en particulier sur les limites concernant les variations de tension, les fluctuations de tension et le phénomène de scintillement dans les systèmes d'alimentation publique basse tension. Cette norme est essentielle car elle établit des seuils acceptables pour les changements de tension causés par des équipements ayant un courant nominal inférieur ou égal à 16 A par phase. Une des forces majeures de cette norme réside dans sa capacité à fournir des limites claires et mesurables, permettant de réduire les impacts négatifs des appareils sur le réseau public électrique. En spécifiant les conditions de test et en fournissant des méthodes d'évaluation, le document facilite également la mise en conformité des appareils avec les exigences techniques en vigueur. Cela s'avère crucial pour les fabricants souhaitant garantir la qualité et la fiabilité de leurs produits. La portée de la norme est parfaitement définie, s'appliquant exclusivement aux équipements électroélectriques destinés aux systèmes de distribution basse tension avec une tension allant de 220 V à 250 V à 50 Hz. Cela assure que les dispositifs qui tombent sous cette catégorie s'alignent sur des critères uniformes lors des tests de compatibilité. De plus, la mention d'une méthode alternative d'évaluation via la norme IEC 61000-3-11 pour les équipements à courant d'entrée supérieur souligne la flexibilité et la pertinence de SIST EN 61000-3-3:2014/A1:2019 dans un environnement technologique en constante évolution. En résumé, SIST EN 61000-3-3:2014/A1:2019 est une norme robuste qui non seulement renforce la fiabilité des équipements électroélectriques, mais joue également un rôle fondamental dans la garantie de la compatibilité électromagnétique des systèmes d'alimentation publique. Ses exigences claires et précises en font un outil indispensable pour tous les acteurs du secteur afin de respecter les standards de qualité.

Der Geltungsbereich dieser Norm deckt elektrische und elektronische Geräte ab, die einen Nennstrom von bis zu 16 A pro Phase haben und für den Anschluss an öffentliche Niederspannungsverteilungssysteme von 220 V bis 250 V bei 50 Hz vorgesehen sind, ohne dass eine bedingte Verbindung erforderlich ist. Ein herausragendes Merkmal dieser Norm ist die klare Festlegung der Grenzen für Spannungsschwankungen, die von derartigen Geräten erzeugt werden dürfen. Diese Vorgaben sind entscheidend, um die Qualität der Stromversorgung zu gewährleisten und um sicherzustellen, dass die Geräte im Einklang mit den EMV-Vorgaben arbeiten. Zudem bietet die Norm wertvolle Hinweise zu den Bewertungsmethoden, was die Umsetzung und Überprüfung von Konformität erheblich erleichtert. Die Relevanz dieser Norm ist sowohl für Hersteller als auch für Anwender von Geräten mit einem Nennstrom bis zu 16 A von großer Bedeutung. Sie ermöglicht eine standardisierte Vorgehensweise zur Bewertung der elektrischen Leistung und hilft dabei, mögliche Störungen im Niederspannungsnetz zu minimieren. Dabei ist besonders zu erwähnen, dass Geräte, die die Vorgaben dieser Norm nicht erfüllen, die Möglichkeit haben, erneut getestet oder bewertet zu werden, um die Konformität mit der angrenzenden Norm IEC 61000-3-11 nachzuweisen. Insgesamt stellt die SIST EN 61000-3-3:2014/A1:2019 einen wichtigen Rahmen dar, der nicht nur die technischen Anforderungen präzise definiert, sondern auch die Sicherheit und Funktionsfähigkeit(public low-voltage supply systems) der elektrischen Infrastruktur unterstützt.
