Scope

As for the spark test of insulated cores (electric wires), this part of GB/T3048 stipulates the
terms and definitions, test facilities, specimen preparation, test procedures, test result and
assessment, calibration of test facilities, and test records.
This part is suitable for testing the insulating layer quality of insulated cores of rubber and
plastic insulated electric cables and wires; it can be used to implement the intermediate
test and routine test of electric cables and wires. It cannot be used to test the insulation
products of conducting cores made of non-conducting materials.
This part includes power frequency spark test and direct current spark test. That is to say,
the test is implemented with power frequency spark machine and direct current spark
machine.
This part shall be used together with GB/T3048.1.
