What is one requirement for materials used in portable fuel tanks?

The requirement for materials used in portable fuel tanks to withstand a temperature range of 0 °F - 140 °F is crucial for ensuring safety and performance in various environmental conditions. Portable fuel tanks are often exposed to extreme temperatures, and materials that cannot handle this range may become brittle or warp, leading to structural failure.

Maintaining integrity within this temperature range is essential to prevent leaks, which can pose serious safety risks, including fire hazards. Additionally, fuels can change properties at different temperatures, affecting their volatility and behavior within the tank.

Choosing materials that can endure both low and high temperatures ensures the tank remains functional, safe, and compliant with industry standards.
