22、d This document (EN 50393:2015) has been prepared by CLC/TC 20 “Electric cables”. The following dates are fixed: latest date by which this document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2015-12-08 latest date by which the nat
23、ional standards conflicting with this document have to be withdrawn (dow) 2017-12-08 This document supersedes EN 50393:2006. EN 50393:2015 includes the following significant technical changes with respect to EN 50393:2006: in Clause 1 Scope, the revised statement referring to existing approvals has
24、been inserted; in Clause 3 Definitions, definitions of stop end types have been revised to align with those of joints, and definitions of rigid and non-rigid joints have been removed; in Clause 6 Range of compliance, the numbers of joint and termination test samples have been increased (see also Tab
25、le 6), compliance restriction and extension with regard to different cable designs have been clarified, and compliance restrictions and extensions relating to conductor connectors have been inserted and shown in a new Table 2; in 7.3, Table 3, joints of Type II are subject to a new test involving 9
26、heating cycles in water without oversheath damage (see also 8.6.2); in 7.3, Tables 3, 4 and 5, the footnotes referring to examination of tested accessories have been removed; in Clause 8 Test methods, the AC voltage withstand test procedure has been simplified and clarified, references to rigid and
27、non-rigid joints have been removed, reference to the 9 cycle test for Type II joints (Table 3) has been inserted, and requirements relating to examination of tested joints have been simplified and references to specific technologies or materials have been removed; Annexes B, C and D have been added
28、to assist in full and accurate identification of test cable, accessories and connectors for inclusion in test reports. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC and/or CEN shall not be held responsible for identifyin

BS EN 50393:2015 5 EN 50393:2015 1 Scope This European Standard details the performance requirements and the test methods for type testing of cable accessories for use with power distribution cables of rated voltage 0,6/1,0 (1,2) kV as defined in HD 603 or other rele
30、vant cable standards. Cable accessories covered by this European Standard include joints, stop ends and outdoor terminations for extruded solid dielectric insulated cables and transition joints between extruded solid dielectric insulated and impregnated paper insulated cables. Joints, stop ends and
31、outdoor terminations for impregnated paper insulated cables are not included. The service operating conditions of accessories should be compatible with the service operating conditions of cables on which they are to be installed. Accessories for special applications such as submarine, shipboard, exp
32、losive or seismic environments, or where specified fire performance characteristics are required, are not included. NOTE 1 This European Standard does not invalidate existing approvals of products achieved on the basis of national standards and specifications and/or the demonstration of satisfactory
33、 service performance. However, products approved according to such national standards or specifications cannot directly claim approval to this European standard. NOTE 2 It may be possible, subject to agreement between supplier and purchaser, and/or the relevant conformity assessment body, to demonst
34、rate that conformity to the earlier standard can be used to claim conformity to this European Standard, provided an assessment is made of any additional type testing that may need to be carried out. Any such additional testing that is part of a sequence of testing cannot be done separately. 2 Normat
