6、tution for standardization e_V.3 . The safety technical requirements and testing3.1 The color markBoth the low voltage cables of a battery jumper cable must be distinguished through the red and black color mark of the clips clearly from each other.Further more the cable can be marked in red and blac
7、k. If the electric cable is filled so that the color marking must belongs to the original clips color. The size which then pliers the color symbolized consistently to maintain the using of the size which symbolized regarding the color to be tested through the examination. 3.2 The complete insulation
8、 of the clipsThe pole clips must be insulated, that a closed and no connected pole clip is not possible to contacting with the electric conductive surface or another clip. This kind of insulating performance test from the clips insulation shall be made through a visible inspection.3.3 Low voltages e
9、lectric cables3.3.1 RequirementThe low voltage electric cable must be suitable for a temperature operational range of -25 +70 and according to DIN ISO 6722 Part 1 & the related electric cable Rank A according to DIN ISO 6722 Part 2 & Part 3.The low voltage electric cable must be bear completely unde
