适用范围

This Harmonization Document 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 of materials does not have a mandatory link to type testing of accessories. It shall be regarded as a stand-alone test, but 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, anti tracking, 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.
