What is BS EN 50393 - Accessories for use on distribution cables of rated voltage 0,6/1,0 (1,2) kV about?
BS EN 50393:2015 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 relevant 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 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, explosive or seismic
environments, or where specified fire performance characteristics are required, are not included.

What’s changed since the last update?
BS EN 50393:2015 supersedes BS EN 50393:2006. BS EN 50393:2015 includes the following technical changes with respect to BS EN 50393:2006:
- In Clause 1 'Scope', the revised statement referring to 'existing approvals' has 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 Table 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 heating cycles in water without oversheath damage (see also 8.6.2) and in 7.3, Tables 3, 4, and 5, the footnotes referring to the 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 '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 the 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 to assist in the complete and accurate identification of test cables, accessories, and connectors for inclusion in test reports.
