EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61156-1-4 testing. IEC EN 61156-1-4 specifies a method for evaluating the thermal behavior of cables arranged in bundles for digital communication. A method for determining the temperature rise in wire bundles for certain remote power currents is described as a basis for analyzing the expected performance under several test arrangements described in the standards for the installation of wiring systems.
It is intended only to provide guidance for evaluating the thermal behavior of cables for digital communication in reference ambient conditions and regulations. As such, it is not intended to become some sort of testing method.
This standard specifies a method for evaluating the temperature rise in cable bundles by measuring the temperature change using thermocouples placed in the cable sheath in the middle of the bundle.
The following test arrangements are considered:
Although this standard covers four-pair data class cables, the same principles can be applied to other cable types.
This temperature is crucial for the compatibility of the insulating material at the interface with the conductor to prevent overheating and sequential deterioration of the insulating and conductive properties. In addition, health and safety issues may arise, such as the danger of melting and potential self-ignition.
