Japanese Automotive Industry Standards And Specifications For Automotive Wire Performance

The Japanese automotive industry has always attached great importance to the performance standards and specifications of automotive wires to ensure the safety, reliability and performance of vehicle electrical systems. The following are some common standards and specifications for automotive wire performance in the Japanese automotive industry:

JASO standard

JASO (Japan Automotive Standards Organization) is one of the organizations that formulates standards for the automotive industry. The standards it develops are widely used in the Japanese automotive manufacturing industry. JASO has developed a series of performance standards for automotive wires, including:

Waterproof performance requirements: The wire should have good waterproof performance and be able to work stably in a humid environment to prevent short circuits and damage.

Heat resistance performance requirements: The wire should have good high temperature resistance and be able to work in high temperature environments such as engine compartments to ensure safety and reliability.

Anti-vibration performance requirements: The wire should have good anti-vibration performance and be able to maintain a stable connection during vehicle driving to prevent the line from loosening or breaking.

Electrical performance requirements: The wire should have good electrical properties, including conductive properties and insulation properties, to ensure the stability and reliability of signal transmission.

JIS standard

JIS (Japanese Industrial Standards) is a series of standards developed by the Japanese National Standardization Committee, which includes some standards related to automotive wires, such as:

JIS C 3306: This standard covers the specifications for insulated wires for automobiles, including regulations on conductor materials, insulation materials, size requirements, etc. to ensure that the quality and performance of the wires meet the requirements.

JIS C 3316: This standard covers the specifications for high-temperature wires for automobiles and specifies in detail the performance requirements of wires in high-temperature environments.

JIS C 3317: This standard covers the specifications of low-voltage wires for automobiles, including provisions on the conductive properties, wear resistance, and waterproof properties of the wires.

OEM requirements

In addition to industry standards, Japanese automobile manufacturers will also formulate their own standards and specifications, putting forward more stringent requirements for the performance and quality of automobile wires. Different car manufacturers may have different standards, but they usually refer to the standards of JASO and JIS and supplement and improve them on this basis.

The Japanese automotive industry has very strict performance standards and specifications for automotive wires to ensure the safety, reliability and performance of vehicle electrical systems. The formulation and implementation of these standards and specifications play an important role in improving the level and competitiveness of the entire automotive industry.
