Standard for Tanks Storing DEF (F091)

The Standard for Tanks Storing DEF (F091) addresses the fabrication of steel tanks, both aboveground and underground, used for the storage of DEF.

Topics include:

• General Requirements
• Tightness Testing
• Application of Internal Lining for Carbon Steel Tanks
• Tank Accessories

The standard is based on the application of sound engineering principles and the combined experience of STI/SPFA membership, users, related manufacturers, regulatory authorities and consultants. DEF must be properly stored to keep the material pure. Contamination of the product could cause it to be unusable.
