NACE RP0285 details the two primary types of cathodic protection systems used for USTs: Galvanic (Sacrificial Anode) Systems

NACE RP0285 (now SP0285) establishes the for using cathodic protection (CP) to control the external corrosion of underground storage tank (UST) systems. It is specifically intended for tanks that are buried, partially buried, or in contact with soil.

It specifies how to install anodes and wiring, including the use of special backfill (e.g., gypsum and bentonite) to enhance performance.

Failure to produce verified testing records aligned with NACE standards during an environmental audit can result in steep fines, mandatory system shutdowns, and forced remediation. Conclusion: The Value of a Verified Standard nace rp 0285 pdf verified

The key to obtaining the correct document lies in understanding this change and the history of the standard: NACE RP0285 details the two primary types of

: This standard does not cover corrosion control through chemical environment modification, internal linings, or non-steel tank materials.

This standard does not cover internal linings or internal corrosion control, nor does it override mandatory safety regulations. Conclusion

Cathodic protection stops corrosion by forcing the entire surface of the underground steel tank to act as a . By introducing an external anode into the soil, electrical current is driven into the tank, neutralizing the naturally occurring corrosive currents. Failure to produce verified testing records aligned with

The standard specifically applies to various components of an underground storage tank system, including:

Usage guidance:

NACE changed the "RP" (Recommended Practice) prefix to "SP" (Standard Practice), turning it into NACE SP0285 .

Originally published as RP0285 by NACE Task Group T-10A-14 to address the urgent need for protecting metallic buried tanks from soil-side corrosion.
