Vehicles, boats and internal combustion engines - Radio disturbance characteristics - Limits and methods of measurement for the protection of off-board receivers
The limits in this International Standard are designed to provide protection for broadcast receivers in the frequency range of 30 MHz to 1 000 MHz when used in the residential environment. Compliance with this standard may not provide adequate protection for new types of radio transmissions or receivers used in the residential environment nearer than 10 m to the vehicle, boat or device. This standard applies to the emission of electromagnetic energy which may cause interference to radio reception and which is emitted from a) vehicles propelled by an internal combustion engine, electrical means or both (see 3.1); b) boats propelled by an internal combustion engine, electrical means or both (see 3.2). Boats are to be tested in the same manner as vehicles except where they have unique characteristics as explicitly stated in this standard; c) devices equipped with internal combustion engines (see 3.3). See Annex G for a flow chart to help determine the applicability of CISPR 12. This standard does not apply to aircraft, traction systems (railway, tramway and electric trolley bus), or to incomplete vehicles. In the case of a dual-mode trolley bus (e.g. propelled by power from either a.c./d.c. mains or an internal combustion engine), the internal combustion propulsion system must be included, but the a.c./d.c. mains portion of the vehicle propulsion system is excluded from this standard. NOTE 2 Protection of receivers used on board the same vehicle as the disturbance source(s) are covered by CISPR 25. The measurement of electromagnetic disturbances while the vehicle is connected to power mains for charging is not covered in this standard. The user is referred to appropriate IEC and CISPR standards which define measurement techniques and limits for this condition. Annex H lists work being considered for future revisions.

Mejne vrednosti v tem mednarodnem standardu so zasnovane za zagotavljanje zaščite sprejemnikov radiodifuzije v frekvenčnem razponu od 30 MHz do 1000 MHz pri uporabi v bivalnih okoljih. Skladnost s tem standardom morda ne bo zagotovila primerne zaščite za nove tipe radijskega oddajanja in sprejemanja, ki se uporabljajo v bivalnih okoljih, ki so bližje vozilu, plovilu ali napravi od 10 m. Ta standard velja za oddajanje elektromagnetne energije, ki lahko povzroči interferenco pri radijskem sprejemu in ki se oddaja iz a) vozil, ki jih poganjajo motorji z notranjim izgorevanjem, električna sredstva ali oboje (glej točko 3.1.); plovila, ki jih poganjajo motorji z notranjim izgorevanjem, električna sredstva ali oboje (glej točko 3.2). Plovila je potrebno preskusiti na isti način kot vozila, razen kadar imajo edinstvene značilnosti, kot je izrecno navedeno v tem standardu; c) naprave, opremljene z motorjem z notranjim izgorevanjem (glej točko 3.3). Glej Dodatek G za shematski prikaz, ki pomaga pri ugotavljanju uporabnosti CISPR 12. Ta standard ne velja za zračna plovila, sisteme vleke (železnica, tramvaj in električni trolejbus) ali za nepopolna vozila. V primeru trolejbusa z dvema načinoma delovanja (npr. ki ga poganja energija bodisi iz izmenične ali enosmerne napeljave ali motor z notranjim izgorevanjem), mora biti vključen sistem notranjega izgorevanja za pogon, vendar je del pogonskega sistema vozila, ki ga predstavljajo izmenične ali enosmerne napeljave, izključen iz tega standarda. OPOMBA 2: Zaščita sprejemnikov, uporabljena v istem vozilu kot vir motenj, je zajeta v CISPR 25. Merjenje elektromagnetnih motenj, medtem ko je vozilo povezano z električnimi napeljavami za napajanje, ni zajeto v tem standardu. Uporabnik naj upošteva primerne IEC in CISPR standarde, ki opredeljujejo tehnike merjenja in omejitve tega pogoja. Dodatek H navaja delo, ki se bo upoštevalo v prihodnjih revizijah.

EN 55012:2007/A1:2009は、車両、ボート、内燃機関のラジオ妨害特性に関する国際基準であり、オフボード受信機を保護するための限界と測定方法を提供します。この標準の適用範囲は、30 MHzから1,000 MHzの周波数帯域において、居住環境での放送受信機を保護することを目的としています。そのため、この基準に準拠することで、電磁エネルギーの放出による干渉を減少させることができます。 この基準の強みは、内燃機関または電気的手段で駆動される車両やボートからの電磁妨害の測定と制限が詳細に定義されている点です。具体的には、3.1から3.3までのセクションでそれぞれの対象となる機器の特性が明記されています。特に、ボートは車両と同様にテストされることが求められ、ユニークな特性がある場合を除外しており、標準が一貫性を持っています。また、CISPR 12の適用性を判断するためのフローチャートが付属しており、実用性が増しています。 さらに、この標準は航空機や軌道交通システム、未完成の車両には適用されないと明記されており、特定の条件に適した基準を参照することが推奨されています。これにより、受信機と干渉源が同じ車両内に存在する場合、CISPR 25に基づいて保護が考慮されます。 この文書は、電磁妨害による影響を管理し、住民の生活環境での放送受信の質を維持するために、非常に重要です。したがって、EN 55012:2007/A1:2009は、現代の多様な無線通信ニーズに応えるための必須の基準として、その適用性と関連性を持っています。
La norme EN 55012:2007/A1:2009 traite des caractéristiques de perturbation radioélectrique des véhicules, des bateaux et des moteurs à combustion interne, en se concentrant sur les limites et les méthodes de mesure nécessaires pour protéger les récepteurs off-board. Le champ d'application de cette norme est particulièrement pertinent dans le contexte résidentiel, où elle fixe des limites de protection pour les récepteurs de diffusion opérant dans une plage de fréquences de 30 MHz à 1 000 MHz. Les points forts de cette norme résident dans sa capacité à harmoniser les exigences de protection contre les perturbations électromagnétiques émises par divers dispositifs, tels que des véhicules à moteur à combustion interne ou électriques, ainsi que des bateaux. En garantissant que les émissions électromagnétiques de ces sources ne compromettent pas le fonctionnement des récepteurs radio dans l'environnement résidentiel, la norme contribue à une meilleure expérience utilisateur pour les habitants situés à proximité de ces équipements. Cependant, il est important de noter que la norme ne couvre pas suffisamment les nouveaux types de transmissions radio ou les récepteurs qui pourraient se trouver à moins de 10 mètres de la source de perturbation, ce qui peut poser des défis concrets face aux évolutions technologiques rapides. De plus, l'exclusion des avions et des systèmes de traction comme les tramways peut restreindre l'application de cette norme à des secteurs spécifiques, laissant un vide pour d’autres modes de transport potentiellement perturbateurs. Globalement, l'EN 55012:2007/A1:2009 reste un document essentiel dans le domaine de la protection contre les interférences radioélectriques, en définissant de manière claire des méthodes de mesure et des limites qui sont cruciales pour la conformité et la sécurité des utilisateurs dans un environnement résidentiel. Le suivi des évolutions au sein des annexes suggère également un engagement à maintenir la norme à jour par rapport aux avancées technologiques et aux exigences du marché.
Die Norm EN 55012:2007/A1:2009 behandelt die elektromagnetischen Störungen von Fahrzeugen, Booten und Verbrennungsmotoren und legt klare Grenzwerte sowie Messmethoden fest, um den Schutz von Empfangsgeräten im Frequenzbereich von 30 MHz bis 1.000 MHz im Wohnumfeld zu gewährleisten. Die Relevanz dieser Norm liegt in ihrer Fähigkeit, sicherzustellen, dass neue Fahrzeug- und Bootstypen, die mit Verbrennungsmotoren oder elektrischen Antrieben betrieben werden, keine unzulässigen Störungen verursachen, die die Funktion von Rundfunkempfängern beeinträchtigen könnten. Ein bemerkenswerter Vorteil dieser Norm ist ihr umfassender Geltungsbereich, der sowohl Fahrzeuge als auch Boote abdeckt und spezifische Testmethoden für die unterschiedlichen Antriebsarten definiert. Darüber hinaus wird durch den klaren Ausschluss von Luftfahrzeugen sowie von unvollständigen Fahrzeugen eine präzise Anwendung auf die vorgesehenen Geräte und Anwendungsfälle sichergestellt. Die Norm hebt auch hervor, dass der Schutz von Empfängern, die sich im selben Fahrzeug wie die Störquelle befinden, durch die Norm CISPR 25 geregelt ist. Zudem bietet die Dokumentation wertvolle Hinweise zur Relevanz für die Messung elektromagnetischer Störungen während des Ladevorgangs über das Stromnetz – ein Aspekt, der in dieser Norm nicht behandelt wird und auf andere IEC- und CISPR-Standards verweist. Die Ergänzung durch Anhänge, die weitere Klärungen und zukünftige Überlegungen zur Norm enthalten, zeigt die dynamische Natur und die fortlaufende Relevanz dieser Normen im Kontext technischer Entwicklungen. Insgesamt stellt die EN 55012:2007/A1:2009 eine wesentliche Grundlage für die Gewährleistung von Funkstörungensschutz dar und ist damit ein wichtiges Dokument für Hersteller, Prüfinstitutionen und Regulierungsbehörden, die sich mit der Gewährleistung eines störungsfreien Empfangs in privaten Umgebungen beschäftigen.
