TEST AT WORKS FOR FIRE RESISTANT MULTICORE CABLES

Routine Tests

 - Max. DC conductors resistance at 20°C acc. to IEC 60228 & IEC 60502-1 parag. 15.1 & 15.2

 - Voltage test acc. to IEC 60502-1  parag.15.1& 15.3

Liban Cables will carry out these tests on all the lengths 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 IEC 60502-1                       Parag.  16.5.2

            Oversheath       :           according to IEC 60502-1                       Parag.  16.5.3

                                                                       

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
