适用范围：This Harmonization Document specifies the test methods and requirements for fingerprinting (asdefined in 3.11) of cold shrinkable components intended to be used in cable accessories for lowand medium voltage, as defined in EN 50393, HD 629.1 and HD 629.2.Fingerprinting of materials does not have a mandatory link to type testing of accessories. It shallbe regarded as a stand-alone test, but may be carried out in combination with the accessory typetests.Component basic functions can be: conductive, stress control or stress grading, insulating, oilbarrier, anti tracking, external protection and sealing. Components are supplied as single layeritems or as multi-layer items.Components are generally supplied pre-expanded or with a system allowing expansion prior toinstallation.NOTE Information on health and safety is given in Annex A.
