1 Scope
This standard specifies the test methods for basic performance and high performance of round, shielded and unshielded multi-core sheathed cables for road vehicles.
Law and requirements.
The individual cores of unshielded cables shall comply with the requirements of GB/T 25085-2010. Other types of cores can also be used, but be sure
The structure and testing required for these core functions shall be determined by negotiation between the supplier and the purchaser. See GB/T 25085-2010 for temperature grades.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
Basic performance (cable) basicperformance(cable)
(Cable) meets the basic requirements of automotive applications.
3.2
Core core
It is inherently insulated and may also have a shielded conductor assembly.
3.3
High performance (cable) highperformance(cable)
(Cable) meets all basic requirements and improved mechanical and/or environmental performance (as determined by the purchaser).
3.4
Shield screen
Conductive materials are used to reduce varying electromagnetic field penetration and/or radiation into designated areas.
3.5
Unshielded unscreened
Missing shielding.
4 General requirements
4.1 Cable rating
4.1.1 Rated voltage
The rated voltage is determined by the rated voltage of the insulated core. 60V and 600V cores should not be mixed in the same multi-core cable.
4.1.2 rated temperature class
The rated temperature rating is determined by the temperature rating of the core and jacket.
4.2 600V cable
Special attention should be paid to protecting cables with voltages above DC60V from mechanical shocks and avoiding the risk of electric shock.
The 600V cable jacket should be identified using a durable orange color.
4.3 Test
Cables shall be tested in accordance with Table 1.
4.4 General test conditions
According to 4.4 of GB/T 25085-2010.
4.5 Oven
According to 4.5 of GB/T 25085-2010.
4.6 Visual appearance
For visual inspection, the sheath should be smooth and flat and should not have lumps, holes, inclusions or other similar defects.
5 size
5.1 Overview
The structure of the cable is varied and the dimensions are determined by both the supplier and the buyer (see 5.2.4, 5.3.5 and 5.4.4).
5.2 Cable outer diameter
5.2.1 Sample
According to 5.1.1 of GB/T 25085-2010.
5.2.2 Installation
According to 5.1.2 of GB/T 25085-2010.
5.2.3 Procedure
According to 5.1.3 of GB/T 25085-2010.
5.2.4 Requirements
The outer diameter of the cable shall be within the range determined by both parties.
5.3 Sheath ellipticity
5.3.1 Test adoption
Whether or not to adopt this test shall be determined by negotiation between the supplier and the buyer.
5.3.2 Sample
According to 5.1.1 of GB/T 25085-2010.
5.3.3 Installation
According to 5.1.2 of GB/T 25085-2010.
5.3.4 Procedure
According to 5.1.3 of GB/T 25085-2010. Determine the maximum (dmax) and minimum (dmin) cable outer diameters, then calculate the ellipticity.
O= dmax-dmin0.5× dmax d( )min ×
In the formula.
O---ellipticity, %;
Dmax---the maximum outer diameter of the cable, mm;
Dmin---the minimum outer diameter of the cable, mm.
5.3.5 Requirements
The ellipticity shall be within the range determined by the supplier and the buyer.
