Permanently mounted mobile motor fuel and RV tanks must be built to which specifications?

Permanently mounted mobile motor fuel and RV tanks must comply with ASME specifications. The American Society of Mechanical Engineers (ASME) develops codes and standards that ensure the safe design, construction, and maintenance of pressure vessels and tanks used in various applications, including those for LP-Gas.

ASME specifications cover aspects such as materials, fabrication methods, quality control, and testing procedures, ensuring that tanks can withstand the pressures associated with storing and dispensing LP-Gas safely. This is critical in preventing leaks, ruptures, or other failures that could lead to dangerous situations.

While DOT also sets standards, those regulations pertain primarily to the transport of hazardous materials rather than the stationary installations involved with permanently mounted tanks. UL focuses on product safety testing and certification, particularly for electrical appliances and components, not specifically for fuel tanks. ISO represents international standards, which can overlap but does not specifically address the design and safety of LP-Gas tanks in the same detail as ASME. Therefore, ASME is the correct specification for ensuring the safety and reliability of these tanks.
