BS EN 50655 is a European Standard that discusses material characterization of electric cable accessories, that can ensure undesired consequences of poor insulation are minimized.
BS EN 50655-2 is the second part of the multi-series that specifies the methods and requirements for fingerprinting of heat shrinkable components intended to be used for electrical insulation and/or electrical insulation and mechanical protection in cable accessories for low and medium voltage, as defined in EN 50393, HD 629.1and HD 629.2.
Fingerprinting of materials does not have a mandatory link to type testing of accessories
BS EN 50655-2 on fingerprinting for heat shrinkable components is relevant to:
Heat shrinkable is a property of a polymeric component previously expanded to recover to its original shape when heated above an appropriate temperature. For optimal performance of electric cable accessories, assessing the performance of these insulating materials and components is critical.
BS EN 50655-2 walks you through the process of fingerprinting for heat shrinkable components, that is a test made to establish and subsequently confirm the properties of materials or components used in cable accessories.
Thus, if you are a manufacturer, compliance with BS EN 50655-2 can help you demonstrate satisfactory performance characteristics of materials or components of a cable accessory to meet the intended application.
