Organization: UL
Publication Date: 17 January 2007
Status: active
Page Count: 74
scope:

These requirements cover pre-engineered corrosion protection systems intended to be factory installed on the exterior surface of steel underground atmospheric-type storage tanks intended for flammable and combustible liquids.

These requirements cover the following systems:

a) Part I for galvanic-type cathodic protection systems.

b) Part II for fiber-reinforced plastic (FRP) composite systems.

c) Part III for polyurethane (PUR), polyurea, high density polyethylene (HDPE) or fiberreinforced plastic (FRP) jacketed systems.

d) Part IV for polyurethane (PUR) coated systems.

These tanks are intended for installation and use in accordance with one or more of the following: Standard for the Installation of Oil-Burning Equipment, NFPA 31; Flammable and Combustible Liquids Code, NFPA 30; Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A; International Fire Code, published by the International Code Council.

These tanks are completely fabricated, inspected and tested for protection system defects and/or tank leakage before shipment from the factory as completely assembled vessels and are intended for burial in accordance with the manufacturers instructions.
