I need to know the national standards or industry standards of automotive wiring harness. Please tell me what you know. Thank you.

1. german automotive wiring harness product standard

DIN 72551 german national standards FLY, FLRY, FLYW

VW 636 Volkswagen standard FLRY FLR6Y FLR7Y FLR13Y FLR31Y

2. Japanese automotive wiring harness product standard

JIS C346 thin-walled insulated low-voltage cable for automobiles AV type Japanese Automotive Engineering Society standard

JASO D611 thin-walled insulated low-voltage cable for automobiles AVS AVSS CAVS

JA. SO D68 Heat-resistant low-voltage cables for automobiles AVX and AEX

3. automotive wiring harness product standard of Korea

KSC 3311 low-voltage wires for automobiles AV type Korean modern enterprise standard

ES 9111- ultra-thin wall PVC insulated low-voltage wires for automobiles AVSS type

4. automotive wiring harness product standard of Italy

FIAT 9117/ 13 T2-15 wire

FIAT 9117/ 15 T3-125 wire

T2-15 PVC insulated low-voltage wire

T3-125 PP insulated low-voltage wire

5. American standard harness wire

American Society of Automotive Engineers standard

SAE 1127 battery cable

SAE 1128 low-voltage primary cable GXL TWP TXL GPT HDT STS HTS SXL TWE G. TE HTE

SAE 1678 low-voltage thin-walled primary cable

MS-8288 cable-primary-thin-walled cross-linked polyethylene insulation

MS-7889 thin thermoplastic (PVC) insulated primary cable

MS-5919 thin-walled cross-linked polyethylene insulated primary cable

6.ISO 6722 standard

7. Ministry standard RVVPRVV

GB/T 2951 general test method for cable insulation and sheath materials

JB/T8139QVR, QVR-15, QVVR

OC/T73-25 thin-walled insulated low-voltage wires for road vehicles

Except that their tests are different, the biggest difference is the wire harness with the same specification.

actually, I really don't understand this question. It's a professional thing. But I also learned something from your question. I wonder if the above can help you.
