Outer dimensions: The average outer dimensions of the cable should meet the requirements of Table 2 to Table 7. The difference between the outer diameters of any two points measured on the same cross section of the round cable should not exceed 15% of the upper limit of the average outer diameter
Mechanical strength of flexible cables
Flexible cables should be able to withstand bending and other mechanical stresses during normal use.
The bending test of the flexible cable should be able to withstand 15,000 reciprocating motions. That is, after 30,000 single-way movements, neither current short circuit nor short circuit between conductors should occur.
Non-flammability test: All cables should meet the test requirements specified in GB/T18380.1.
