The USCAR-2 standard that everyone knows about connectors, SAE/USCAR-2 REBISION 8， American Automotive Connector Testing Standards

What is USCAR?
USCAR
Automotive Connectors and wiring harnesses are an indispensable part of modern cars, carrying the functions of electrical signals and power transmission. USCAR (United States Council for Automotive Research) is an organization that develops and promotes standards in the automotive industry. This article will explore the importance of the USCAR automotive leveling tool and its application areas in the automotive industry.

1 USCAR Introduction
USCAR is a standard jointly drafted and developed by Stellantis, Ford, and General Motors. Its mission is to promote technological cooperation and standardization in the automotive industry, in order to enhance the competitiveness and efficiency of the entire industry. USCAR plays an important role in developing standards, one of which is the automotive connector and wiring harness standard.

3 The importance of automotive connectors and wiring harness standards
Automotive connectors and wiring harnesses are the core components of automotive electrical systems, connecting various electronic devices and sensors to ensure their proper functioning. The development of automotive connector and wiring harness standards is of the following importance to the entire industry:
Ensuring safety: The automotive connector and wiring harness standards ensure the safety performance of connectors and wiring harnesses, including fire resistance, high temperature resistance, wear resistance, etc., to reduce potential electrical faults and accident risks.
Improving quality and reliability: Standardized connector and harness design and manufacturing processes can enhance the quality and reliability of connectors and harnesses, reduce failure rates and after-sales issues.
Cost reduction: Unified standards can reduce the time and cost required for producing wire harnesses, simplify supply chain management, and make the entire industry more efficient.

4 Application areas of automotive connectors and wiring harness standards
The application of automotive connectors and wiring harness standards covers the entire automotive industry, mainly including the following aspects:
Automakers: Automakers design and manufacture connectors and wiring harnesses in accordance with USCAR standards to ensure their products meet industry requirements and enhance product competitiveness.
Component suppliers: The application of connector and harness standards requires component suppliers to provide connectors and harness products that meet the standards to meet the needs of automotive manufacturers.
Research and development institutions and standardization organizations: USCAR collaborates with research and development institutions and standardization organizations to jointly develop and update automotive connector and wiring harness standards, promoting technological progress in the industry.

5、 SAE/USCAR-2 standard
USCAR 2 was released by the Society of Automotive Engineers (SAE) in 2008, covering performance testing at various stages of the development, production, and on-site analysis of electrical terminals, connectors, and components that make up high-voltage (60-600V) road vehicle application electrical connection systems. USCAR 2 is currently one of the most commonly used standards in the connector industry, with the latest version being SAE/USCAR-2 REBISION 8.
