Purchasing or downloading an officially verified standard from the ANSI Webstore or the Accuris Standards Store ensures you are not using outdated, superseded text that could invalidate your regulatory compliance audits. Core Technical Criteria for Cathodic Protection

The standard (reissued as NACE SP0285 by the Association for Materials Protection and Performance - AMPP) is the foundational global framework for controlling external corrosion on Underground Storage Tank (UST) systems using cathodic protection (CP) . Originally published in 1985 by NACE International, this engineering standard provides the minimum technical criteria required to safeguard buried mild-steel tanks, piping, and electrical connectors from structural degradation. Relying on verified PDF copies of this standard ensures that compliance officers, asset owners, and field engineers avoid outdated revisions and dangerous installation errors.

There is no shortcut to compliance. Below are the for a verified copy of NACE RP 0285 (SP0285).

The standard outlines specific criteria to confirm that a UST system is successfully protected against corrosion. These criteria are verified using a calibrated copper/copper sulfate reference electrode (CSE) placed in the soil directly over the structure. Criterion Type Voltage Requirement Measurement Conditions -850 mV or more negative

It provides minimum requirements and guidelines for establishing external corrosion control on buried or partially buried metallic UST systems, specifically focusing on the application of cathodic protection (CP). Key Content of NACE RP0285/SP0285

The standard was first released as RP 0285 ("Recommended Practice") to address environmental risks from leaking underground fuel tanks.

The official store hosted by the Association for Materials Protection and Performance is the primary source for the verified PDF.

: Mandates that cathodic protection (CP) systems be designed and maintained by qualified professionals, such as NACE-certified CP Specialists or registered professional engineers. Protection Criteria

Using metals like magnesium or zinc that corrode instead of the tank.

: A trusted provider for corporate licensing of engineering standards and technical documents.

: Offers detailed references and tracking for various revisions of the standard. GALL Aging Management Program AMP M41 Buried Piping
