This standard BS EN 50655-3:2017 Electric cables. Accessories. Material characterization is classified in these ICS categories:
- 29.035.20 Plastics and rubber insulating materials
- 29.060.20 Cables
This European Standard specifies the test methods and requirements for fingerprinting (as defined in 3.11) of cold shrinkable components intended to be used in cable accessories for low and medium voltage, as defined in EN 50393, HD 629.1 and HD 629.2.
Fingerprinting testing of materials does not have a mandatory link to type testing of accessories. It is regarded as a stand-alone test, but it may be carried out in combination with the accessory type tests.
Component basic functions can be conductive, stress control or stress grading, insulating, oil barrier, antitracking, external protection and sealing. Components are supplied as single layer items or as multi-layer items.
Components are generally supplied pre-expanded or with a system allowing expansion prior to installation.
NOTE Information on health and safety is given in Annex A.
