UEL stands for which phrase?

Explanation:
Flammable limits define the range where ignition can occur. The upper end of that range is the highest concentration of vapor in air that can still ignite—above this, the mixture is too rich to burn. That boundary is called the Upper Explosive Limit. So the acronym UEL stands for Upper Explosive Limit. The other phrases don’t describe the flammable-vapor boundaries used in safety and fuel handling.
