What is the standard for automotive wiring harness tension? What are the specific standards?

The tension standard for automotive wiring harnesses refers to the regulations on the greater tension or tension that automotive wiring harnesses can withstand during installation and use. These standards aim to ensure that the wiring harness is not subjected to excessive stress under normal working conditions, in order to ensure its safety and reliability.
The specific tension standards for automotive wiring harnesses vary depending on different industries and applications. Here are some common standards:
ISO 6722: This is a standard for automotive electrical wiring harnesses published by the International Organization for Standardization (ISO). Among them, ISO 6722-1 specifies the greater tensile force that different categories of wire harnesses should experience, and the specific values vary depending on the category, diameter, and usage conditions of the wire harness.
SAE J1939: This is a standard for commercial vehicle communication networks published by the Society of Automotive Engineers (SAE) in the United States. Among them, SAE J1939-11 specifies the tensile testing method and standards for wire harnesses.
GMW3172: This is a specification for wiring harnesses and cables released by General Motors. Among them, GMW3172 specifies the tension standards for different types of wiring harnesses, including sensor wiring harnesses, power wiring harnesses, and data wiring harnesses.
Ford ES-XW7T-1A278-AC: This is a specification for wiring harnesses and cables released by Ford Motor Company. Among them, ES-XW7T-1A278-AC specifies the tensile standards, testing methods, and requirements for different types of wire harnesses.
These standards are usually classified based on factors such as wire harness type, diameter, material, and usage environment, and corresponding tensile standards are specified. For example, the requirements for sensor wiring harnesses and power wiring harnesses may differ due to their different positions and functions in the vehicle.
The standard for wire harness tension is usually expressed in Newton (N) or kilogram force (kgf), and the specific values vary depending on different standards and specifications. To ensure the reliability of the wiring harness, manufacturers and suppliers usually conduct tensile tests according to relevant standards and ensure that the wiring harness can withstand the specified tensile force during installation and use without causing the harness to break or be damaged.
