BS EN 50393:2015 pdf download.Test methods and requirements for accessories for use on distribution cables of rated voltage 0,6/1,0 (1,2) kV.
Compliance will be gained for a product family of the same design and materials by successfully completing the appropriate test sequence in Tables 3, 4 or 5 on the smallest and the largest accessory in the family. In the case of joints and outdoor terminations, the smallest and largest accessory shall each be tested with the smallest and largest specified cable conductor cross-sections (total 4 samples). Stop-ends shall be tested with the smallest and largest conductor cross-sections (2 samples).
The range of compliance will include these accessories and the intermediate sizes within the family The number of test samples is shown in Tables 6 to 9. Successful testing with only one cable conductor cross-section shall give compliance for that cross-section only.
6.2 Cables
6.2.1 Compliance is restricted to the use of the accessories on the same cable type (construction and materials) as used in the tests, subject to the permitted extensions given in 6.2.2 to 6.2.5.
6.2.2 Compliance shall extend to the use of the accessories with cables having different conductor material or construction provided that the connectors used in the tests are compliant with 4.1.
6.2.3 Compliance gained for accessories tested on cable with shaped conductors shall extend to the use of the same accessories on cables with circular conductors, subject to the restrictions of 4.1 and 6.3. The converse shall not apply.
6.2.4 Compliance shall extend to use of the accessories with cables having conductor insulation different from that of the test cables in accordance with Table 1.
IPC type connectors shall have been tested on all of the conductor insulation types for which range extension is required.
6.2.5 Compliance gained for accessories tested on cable without longitudinal water-blocking shall extend to their use on water-blocked cable that is otherwise of the same design and materials. The converse shall not apply.
6.2.6 Compliance gained for accessories with a connector tested on cable with longitudinal water- blocked conductors shall extend to their use on cable with non-water-blocked conductor. The converse shall not apply.
6.2.7 Compliance gained for an accessory shall be extended to the use of the same accessory on cables of the same design and materials but with fewer cores.
6.3 Connectors for joints
Compliance gained for joints shall be restricted to the use of the same conductor connectors as those used in the tests, together with other connectors meeting the requirement of 4.1 and falling within the extension limitations detailed in Table 2. The extensions permitted in Table 2 are based on geometrical considerations only and do not imply any similarity or difference in connector performance.BS EN 50393 pdf download.
