Product Testing Methods
Supports
The brackets are characterised by their permissible loads (in Kg).
The hangers are characterised by their permissible torques (in Kg.m). All Marco supports are tested and conform with the standard BSEN61537. The safe working load (SWL) as defined by the standard is the lowest value of either: The load creating a deflection of L/20 at the end The breaking load divided by 1.7, if the deflection at L/20 is not reached
L
MAX L20mm
Electro-Magnetic Compatibility
Marco engage the services of York EMC, part of The University of York, to investigate shielding effectiveness of Marco steel wire cable tray. Marco steel wire cable tray is found to outperform the 200mm pacing configuration required by BSEN50174-2 proven by the independently commissioned EMC tests. This indicates that Marco steel wire cable tray can offer a more efficient and compact installation (rather than relying on spacing).
