After enquiries and votes carried out in accordance with the rules of this Association, this European Standard has received the approval of the National Association
20、s and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2018, and conflicting national standards shall b

BS EN 3475701:2017EN 3475-701:2017 (E) 4 1 Scope This European Standard specifies methods of mea
24、suring the strippability and adherence of the insulation to a conductor of a finished cable. When a particular method is not specified in the detail product specification, method A shall be used. Method B is recommended for wires insulated with materials showing a Low adhesion to the conductor due t
25、o the poor repeatability of the test Method A with this type of wires. It shall be used together with EN 3475-100. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only th
26、e edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

27、cimens 3.1 General Measurement shall be done on samples directly out of a reel or out of a coil with a minimum of deformation. 3.2 Insulation stripping properties Stripping shall be carried out without difficulty over 5 mm for cables with sections up to 5 mm2and over 8 mm for cables with a section g
28、reater than 5 mm2at the two ends of each specimen using the stripping tools in accordance with EN 2812. The manufacturer shall state in the test report which tools have been used. 3.3 Adherence of insulation to the conductor 3.3.1 Method A The adherence of the insulation shall be adequate when tests
29、 are carried out on the specimens prepared according to Figure 1. The insulation shall be cut around the whole periphery of each specimen 5 mm and 30 mm from one end (for sizes up to 5 mm2). The insulation shall then be stripped from both ends to leave a length of insulation on the conductor. Figure
30、 1 BS EN 3475701:2017EN 3475-701:2017 (E) 5 3.3.2 Method B The adherence of the insulation shall be adequate when tests are carried out on the specimens prepared according to Figure 2. The insulation shall be cut around the whole periphery of each specimen 5 mm and 55 mm from one end. The insulation
31、 shall then be stripped from both ends to leave a length of insulation on the conductor. Figure 2 4 Methods 4.1 Method for stripping capability of the jacket (screened cables) The stripping capability is characterized by the time required to strip a 80 mm length of the jacket. A suitable tool shall
32、be used. 4.2 Methods for adherence of the insulation 4.2.1 Method A Pass the conductor through a calibrated hole (conductor diameter + 0,05 mm) and subject it to an increasing tensile force F until it slides inside the insulating cover. The tensile speed shall be (100 10) mm/min. 4.2.2 Method B Thre
33、e (3) measurements per sample are required. Pass the conductor through a calibrated hole (conductor diameter + 0,05 mm) and subject it to an increasing tensile force F until it slides inside the insulating cover. The tensile speed shall be (100 10) mm/min. 5 Requirements 5.1 Requirements for strippi
34、ng capability of the jacket (screened cables) The stripping operation shall not exceed 40 s for a suitably skilled operator. BS EN 3475701:2017EN 3475-701:2017 (E) 6 5.2 Requirement for adherence of the insulation 5.2.1 Method A The minimum values of the forces of adherence shall be at least equal t
35、o the values specified in the technical specification. 5.2.2 Method B The minimum value of each measurement of the force of adherence shall be at least equal to the value specified in the product standard. If one measurement is less than the value specified in the product standard, two (2) other mea
36、surements are done. The median value of the five (5) measurements shall be at least equal to the value specified in the product standard.
