CISPR 16-4-2:2011

Specification for radio disturbance and immunity measuring apparatus and methods - Part 4-2: Uncertainties, statistics and limit modelling - Measurement instrumentation uncertainty

CISPR 16-4-2:2011 is a basic EMC publication. It specifies the method of applying Measurement Instrumentation Uncertainty (MIU) when determining compliance with CISPR disturbance limits. The material is also relevant to any EMC test when interpretation of the results and conclusions reached will be impacted by the uncertainty of the measurement instrumentation used during testing. This second edition includes significant technical additions about methods of conducted disturbance measurements on mains and communication ports and about methods of radiated disturbance measurements using a FAR in the ranges of 30 MHz to 1 000 MHz and of 1 GHz to 18 GHz. The annexes contain the background material used in providing the amount of MIU found in generating the CISPR values shown in the main document and hence provide valuable background material for those needing both initial and further information on MIU and how to take individual uncertainties in the measurement chain into account. The annexes, however, are not intended to be a tutorial or user manual or to be copied when making uncertainty calculations. For that purpose, the references shown in the bibliography, or other widely recognized documents, may be used. Measurement instrumentation specifications are given in the CISPR 16-1 series, while the methods of measurement are covered in the CISPR 16-2 series. Further information and background on CISPR and radio disturbances is given in CISPR 16-3. The other parts of the CISPR 16-4 series contain further information on uncertainties in general, statistics and limit modelling. The contents of the corrigendum of April 2013 have been included in this copy.

Spécifications des méthodes et des appareils de mesure des perturbations radioélectriques et de l'immunité aux perturbations radioélectriques - Partie 4-2: Incertitudes, statistiques et modélisation des limites - Incertitudes de mesure de l'instrumentation

La CISPR 16-4-2:2011 est une publication fondamentale en CEM. Elle spécifie la méthode d'application de l'incertitude de mesure de l'instrumentation (MIU) à la détermination de la conformité aux limites de perturbation du CISPR. Cela s'applique également à tous les essais CEM lorsque l'interprétation des résultats et les conclusions peuvent être influencées par l'incertitude de l'instrumentation de mesure utilisée pendant les essais. Cette deuxième édition constitue une révision technique. Elle inclut les modifications techniques majeures concernant les méthodes de mesure des perturbations conduites via les accès secteur et les accès télécommunication, ainsi que concernant les méthodes de mesure des perturbations rayonnées au moyen d'une FAR, dans la gamme de fréquences de 30 MHz à 1 000 MHz et de 1 GHz à 18 GHz. Les annexes contiennent les éléments de référence utilisés pour fournir la quantité de MIU trouvée dans l'élaboration des valeurs CISPR indiquées dans le document principal, et en conséquence, fournissent également des informations importantes pour ceux qui ont besoin à la fois d'informations initiales et complémentaires sur les MIU et sur la façon de prendre en compte les incertitudes individuelles dans la chaîne de mesure. Toutefois, les annexes ne sont pas destinées à être un modèle didactique ou un manuel d'utilisateur ou encore à être reproduites pour effectuer des calculs d'incertitude. A cet effet, il est possible d'utiliser les références fournies dans la bibliographie ou dans d'autres documents de fiabilité reconnue. Les spécifications des instruments de mesure sont données dans la série CISPR 16-1 et les méthodes de mesure sont couvertes par la série CISPR 16-2. Des informations complémentaires et références contextuelles sur les perturbations CISPR et radioélectriques sont données dans la CISPR 16-3. Les autres parties de la série CISPR 16-4 contiennent des informations complémentaires sur l'incertitude en général, les statistiques et la modélisation des limites. Le contenu du corrigendum d'avril 2013 a été pris en considération dans cet exemplaire.
