Which DOT specification has a design pressure range of 5-25 psi?

Explanation:
Design pressure is the maximum internal pressure a cargo tank is built to safely withstand in service. A range of 5–25 psi identifies a low‑pressure liquid cargo tank. Among the DOT specifications listed, DOT 412 is the one defined for this low-pressure category, so it best fits the 5–25 psi design pressure requirement. The other specifications describe different tank designs or service pressures, so they don’t match the 5–25 psi range.
