BS PD CLC/TR 50659:2017 provides test methods for the measurement of the following electromagneticcharacteristics of lengthwise cable management systems like conduit systems according to EN 61386series, cable trunking systems and cable ducting systems (CTS/CDS) according to EN 50085 seriesand cable tray and cable ladder systems according to EN 61537:

shielding effectiveness of magnetic field,
transfer impedance.

This Technical Report also provides guidance on how these characteristics can be declared and may beused.Powertrack systems covered by EN 61534 series are not covered by this edition of the Technical Reportand may be considered in a new edition.Cross References:EN 61000-4-5IEC 61000-4-5EN 61000-5-7IEV IEC 60050EN 50085EN 60060-1:2010IEC 60060-1:2010EN 61386EN 61534 EN 61537IEC 61537
