The Society of Automotive Engineers is responsible for:

The Society of Automotive Engineers (SAE) is indeed primarily known for creating standards and specifications that enhance safety, reliability, and performance in the automotive industry. This includes the development of standards for various automotive fluids and equipment, which helps ensure compatibility and efficiency across different vehicles and components.

This standardization is crucial for manufacturers, as it promotes uniformity in the industry, allowing for better diagnostics, maintenance, and overall vehicle performance. By establishing clear standards, SAE plays a key role in guiding manufacturers in their processes and contributing to the overall quality and safety of automotive products.

In contrast, while the other activities mentioned—such as setting engine emissions regulations, testing vehicles, and manufacturing parts—are significant in their own right, they fall outside the primary focus of the SAE. Emissions regulations are typically the purview of environmental and governmental bodies, vehicle testing is often done by manufacturers themselves or independent testing organizations, and manufacturing automotive parts is conducted by various companies rather than a standards organization like SAE.
