Emc Management: How to Compare Electromagnetic Environmental Measurements and Equipment Immunity Levels

“…Since immunity levels 2 and 3 are the most commonly applied levels to equipment projected to operate under hostile electromagnetic environments, it is not difficult to find a number of papers using 3 and 10 V/m as a reference limit [1][2][3][4][5][6][7][8][9].…”

“…As previously mentioned, a straightforward comparison of electromagnetic environment measurements and immunity levels for electroelectronic equipment has been used in the technical literature as a usual method to provide EMC management within critical areas [1][2][3][4][5][6][7][8][9]. However, it is possible to show that this approach may lead to wrong or overly conservative results.…”

“…Using standard uncertainty u(x i ) provided this table it is possible to perform a suitable development in order to calculate the combined standard uncertainty u c . It is evaluated according to (6):…”

“…For instance, a number of important papers regarding this scope can be listed here for hospital environment assessments [1][2][3][4][5][6][7][8][9]. Most of them usually compare environmental measurements with the immunity levels (3 or 10 V/m) prescribed for electromedical equipment according to IEC 60601-1-2 (EMC collateral standard).…”

Medición del Campo Eléctrico Ambiente de Alta Frecuencia en un Hospital

“…En los últimos años las mediciones han seguido evaluando las frecuencias anteriormente citadas (Davis et al, 2000;Phaiboon & Somkuarnpanit, 2000) y la reciente banda ISM (Industrial, Scientific and Medical) a 2,4 GHz (Tan et al, 2001). En Colombia, Sánchez et al (2006) midieron el campo eléctrico dentro de un hospital con el fin de tener indicios sobre el ambiente electromagnético en: la banda ISM en la cual operaba la red inalámbrica instalada en el hospital y sobre las bandas UNII I y UNII II, en las cuales pueden operar algunas redes inalámbricas.…”
