Importance of EMC/EMI and Environmental Testing in Transportation

EMC/EMI Testing

Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) testing are crucial in assessing how electronic components in transportation systems interact with electromagnetic fields and ensuring they function reliably without causing or being affected by unwanted electromagnetic energy​​​​.

Environmental Testing

This testing assesses equipment durability and performance under various environmental conditions such as temperature, humidity, vibration, and exposure to chemicals. It helps in ensuring that transportation equipment can withstand the diverse conditions it may encounter during operation​​.

Standards in Transportation Testing

Testing standards play a vital role in the transportation industry by setting benchmarks for equipment performance and safety.

These standards are critical in ensuring that transportation equipment can withstand a range of environmental conditions, thereby enhancing the safety, reliability, and performance of transportation systems.

They guide manufacturers and designers in developing equipment that meets rigorous industry and regulatory standards. They also play a key role in the transportation industry’s commitment to safety and quality.

SAE J1455

SAE J1455, Recommended Environmental Practices for Electronic Equipment Design in Heavy-Duty Vehicle Applications, provides comprehensive guidelines for the design of electronic systems and components in heavy-duty vehicles.

The SAEJ1455 standard also addresses various environmental factors impacting the performance and reliability of these systems. Key aspects of the standard include:

Environmental Factors: SAE J1455 covers a wide range of environmental factors that affect electronic equipment in heavy-duty vehicles. This includes mechanical, chemical, and biological stresses​​.

Testing Protocols: The standard references other test protocols to evaluate the resistance of components to environmental conditions like corrosion caused by salt spray atmospheres​​.

Specific Tests: The standard includes various tests, such as temperature cycle tests, thermal shock tests, thermal humidity cycling, and salt spray tests (ASTM B117). It also encompasses tests for exposure to chemicals and oils, fungus, dust and sand, gravel bombardment, altitude, mechanical vibration and shock, and combined environmental testing​​.

ISO 16750:  Road Vehicles – Environmental Conditions and Testing for Electrical and Electronic Equipment

ISO 16750 is a series of standards providing guidance on environmental conditions commonly encountered by electrical and electronic systems in automobiles. It specifies requirements and tests across various conditions:

AREMA Part 11.5.1: Communications & Signals Testing

This standard, recommended by the American Railway Engineering and Maintenance-of-Way Association (AREMA), specifies environmental requirements for electrical and electronic equipment used in railroad signal systems.

It covers aspects like temperature (operating and storage), relative humidity (operating and storage), vibration, mechanical shock, EMI, dielectric strength, and abrasive environment.

EN 50155: Rolling Stock – Electronic Equipment Testing

EN 50155 compliance testing is a European standard that covers electronic equipment used on rolling stock for railway applications.

The standard addresses various aspects of this electronic equipment, including temperature, humidity, shock, vibration, and other parameters​​.


MIL-STD-810, developed by the U.S. Department of Defense, is a comprehensive standard that emphasizes tailoring an equipment’s environmental design and test limits to the conditions it will experience throughout its service life.

The standard covers a broad range of environmental conditions including altitude testing, exposure to extreme temperatures, rain, humidity, fungus, salt fog for rust testing, sand and dust exposure, explosive atmosphere, leakage, acceleration, shock and transport shock, gunfire vibration, and random vibration. Although initially prepared for military applications, MIL-STD-810 is also widely applied in commercial products.

Common Industries Associated with Transportation

Several industries are intricately linked to transportation. Industries include automotive manufacturing, aerospace, maritime, and rail industries. These sectors depend heavily on transportation testing and compliance standards to ensure the safety, reliability, and efficiency of their equipment and services.
