NOTE It has been assumed in the preparation of this document that the execution of its provisions will be entrusted to appropriately qualified and experienced people, for whose use it has been produced. WARNING This European Standard calls for the use of substances and/

26、or procedures that may be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. BS EN 506553:2017EN 50655-3:2017 4 1 Scope This European Standard specifies th

27、e 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

28、 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, anti-tracking, external protection and sealing. Components are suppli

29、ed 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. 2 Normative references The following documents, in whole or in part, are normatively

41、t on cold shrinkable components as defined in Table 1. 4.2 Sampling Samples for fingerprinting shall be taken from material stored under conditions prescribed by the supplier. The fingerprinting test on cold shrinkable components shall be carried out a) either as a stand-alone test. Samples used for

42、 the initial test shall be taken from material available with or without sealant as agreed between supplier and user, b) or in combination with an accessory type test. Samples used for the initial test shall be taken from the same batch as those used in the accessory type test with or without sealan

43、t. In the event that no material from the same batch is available, the samples used for the initial test shall be taken from material available as agreed between supplier and user. 4.3 Preparation and conditioning Original components shall be individually prepared and conditioned in accordance with

44、relevant test method conditions. For multi-layer components, the material samples shall be taken from individual layers. 4.4 Tests Components shall be tested in accordance with the tests specified in Table 1. 4.5 Test report The test report shall include the following data: 1) part number or identif
