This document provides test methods for the measurement of the following electromagnetic characteristics of lengthwise cable management systems like conduit systems according to EN 61386 series, cable trunking systems and cable ducting systems (CTS/CDS) according to EN 50085 series and cable tray and cable ladder systems according to EN 61537: – shielding effectiveness of magnetic field, – transfer impedance. This document also provides guidance on how these characteristics can be declared and may be used.
