Routine Tests                                                              

 - Max. DC conductor resistance at 20°C acc. to IEC 60228

 - Spark test during insulation


Liban Cables will carry out these tests on all the length and tests certificates will be provided.                                                                  


Sample Tests

 -          Check of the build - up and color coding of the cable                                                      

 -          Check of dimensions                                                    

            Insulation          :           according to VDE 250  Table 6  Column 2                                  



These tests will be carried out on one length of each size during each inspection .

Tests certificates will be provided by Liban Cables                                                                      


Type Tests                                                                  

Mechanical characteristics on insulation  material (tensile strength and elongation at break) in accordance with VDE 250.

Fire retardance test according to IEC 60332-3

These tests will be carried out on one length of the order

Tests certificates will be provided by Liban Cables
