Industrial, scientific and medical equipment - Radio-frequency disturbance characteristics - Limits and methods of measurement
CISPR 11:2015 is available as CISPR 11:2015 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
CISPR 11:2015 applies to industrial, scientific and medical electrical equipment operating in the frequency range 0 Hz to 400 GHz and to domestic and similar appliances designed to generate and/or use locally radio-frequency energy. This standard covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz. Measurements need only be performed in frequency ranges where limits are specified in Clause 6. For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations (see Definition 3.13), this standard covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz. Requirements for ISM RF lighting equipment and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this standard. Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this standard. This sixth edition cancels and replaces the fifth edition published in 2009 and its Amendment 1 published in 2010. It constitutes a technical revision. It introduces and permits type testing on components of power electronic equipment, systems and installations. Its emission limits apply now to low voltage (LV) a.c. and d.c. power ports, irrespective of the direction of power transmission. Several limits were adapted to the practical test conditions found at test sites. They are also applicable now to power electronic ISM RF equipment used for wireless power transfer (WPT), for instant power supply and charging purposes. The limits in the range 1 GHz to 18 GHz apply now to CW-type disturbances and to fluctuating disturbances in a similar, uniform and technology-neutral way. For these measurements, two alternative methods of measurement are available, the traditional log-AV method and the new APD method. It has the status of a Product Family EMC standard in accordance with IEC Guide 107, Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications (2014).
Appareils industriels, scientifiques et médicaux - Caractéristiques de perturbations radioélectriques - Limites et méthodes de mesure
La CISPR 11:2015 est disponible sous forme de CISPR 11:2015 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
La CISPR 11:2015 s'applique aux appareils industriels, scientifiques et électromédicaux fonctionnant dans la plage de fréquences de 0 Hz à 400 GHz, ainsi qu'aux appareils domestiques et similaires conçus pour produire et/ou utiliser, dans un espace réduit, de l'énergie radioélectrique. La présente norme couvre les exigences d'émission relatives aux perturbations radioélectriques dans la plage de fréquences de 9 kHz à 400 GHz. Les mesurages sont seulement nécessaires dans les plages de fréquences dans lesquelles les limites sont spécifiées à l'Article 6. Pour les applications industrielles, scientifiques et médicales (ISM) à fréquences radioélectriques, au sens de la définition fournie par le Règlement des radiocommunications de l'UIT (voir Définition 3.13), la présente Norme couvre les exigences d'émission relatives aux perturbations à fréquences radioélectriques dans la plage de fréquence comprise entre 9 kHz et 18 GHz. Les exigences relatives aux appareils d'éclairage ISM à fréquences radioélectriques et aux générateurs de rayonnement UV fonctionnant dans les bandes de fréquences ISM définies par le Règlement des radiocommunications de l'UIT sont spécifiées dans la présente Norme. Les installations couvertes par d'autres normes de produits du CISPR et d'autres normes d'émission de famille de produits n'entrent pas dans le domaine d'application de la présente norme. Cette sixième édition annule et remplace la cinquième édition parue en 2009 et son Amendement 1 paru en 2010. Cette édition constitue une révision technique. Elle introduit et permet des essais de type sur des composants d'appareils, de systèmes et d'installations électroniques d'alimentation. Ses limites d'émission s'appliquent désormais aux accès d'alimentation en courant alternatif et en courant continu à basse tension (BT), quel que soit le sens de la transmission d'énergie. Plusieurs limites ont été adaptées aux conditions d'essai pratiques déterminées sur les sites d'essai. Elles s'appliquent désormais également aux appareils ISM à fréquences radioélectriques électroniques de puissance utilisés pour le transfert de puissance sans fil (WPT), l'alimentation électrique instantanée et les besoins de la mise en charge. Les limites dans la plage comprise entre 1 GHz et 18 GHz s'appliquent désormais aux perturbations de type à ondes entretenues et aux perturbations fluctuantes de manière similaire, uniforme et neutre d'un point de vue technique. Pour ces mesurages, deux autres méthodes de mesure sont disponibles: la méthode Log-AV traditionnelle et la nouvelle méthode APD. Elle a le statut d'une norme de famille de produits en CEM, conformément au Guide 107 de l'IEC, Compatibilité électromagnétique - Guide pour la rédaction des publications sur la compatibilité électromagnétique (2014).
