DIN EN 62489-2
Electroacoustics - Audio-frequency induction loop systems for assisted hearing - Part 2: Methods of calculating and measuring the low-frequency magnetic field emissions from the loop for assessing conformity with guidelines on limits for human exposure (IEC 62489-2:2014); German version EN 62489-2:2014
Akustik - Audiofrequenz-Induktionsschleifenanlagen zur Unterstützung von Hörsystemen - Teil 2: Verfahren zur Berechnung und Messung der niederfrequenten Emissionen des durch die Schleife erzeugten Magnetfeldes zur Einschätzung der Konformität mit Richtlinien zu Grenzwerten für die Belastung des Menschen (IEC 62489-2:2014); Deutsche Fassung EN 62489-2:2014
Overview
An adaptation of DIN EN 62489-2 has become necessary: a) by the revision of the ICNIRP Guide in the 2010 edition; b) by the amendment of the physical quantity on which restrictions are established, from tissue current density to induced electric field; c) by changes of reference levels; d) by simplification of the application of the guidelines. DIN EN 62489-2 is a state-of-the-art which shall be observed for the audio-frequency induction loop system. The responsible committee is Joint Subcommittee DKE/GUK 821.6 "Hörgeräte und audiometrische Messtechnik" ("Hearing aids and audiometric measurements") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
