What must CNG (compressed natural gas) fuel containers comply with?

Compressed natural gas fuel containers must comply with 49 CFR 571.304, which pertains specifically to the Federal Motor Vehicle Safety Standards (FMVSS) and establishes criteria for the safety performance of fuel systems in motor vehicles. This regulation ensures that fuel containers are designed and constructed to withstand pressure and other conditions encountered during normal operation, as well as potential impact scenarios. Compliance with this standard ensures the safety and integrity of CNG fuel systems, protecting both the vehicle occupants and the environment.

The other regulations mentioned focus on different aspects of vehicle safety and performance and do not specifically address the requirements for CNG fuel containers. It’s essential for industry professionals to be familiar with these regulations to ensure that vehicles are compliant and safe when operating on CNG fuels.
