What is the minimum static force that vehicle cylinder brackets must withstand when fully pressurized?

The minimum static force that vehicle cylinder brackets must withstand when fully pressurized is specified to be at least 8 times the weight of the cylinder. This standard is important because it accounts for various stress factors that can occur during operation, such as acceleration, deceleration, and unexpected bumps or impacts on the roadway. By requiring the brackets to support a force greater than just their weight, this ensures a significant safety margin, minimizing the risk of failure under dynamic conditions. Such guidelines are put in place to enhance the overall safety and structural integrity of the vehicle's fuel system.

The other possibilities would not meet the specified safety standards typically recommended in regulatory guidelines for compressed natural gas systems.
