I’m unable to directly provide or link to a verified PDF of (now often redesignated as NACE SP0285 , “Corrosion Control of Underground Storage Tank Systems by Cathodic Protection”). However, I can guide you on how to obtain a verified copy:
Water flow problems can have significant impacts on industrial operations, including reduced efficiency, increased maintenance costs, and even safety risks. By following the guidelines outlined in NACE RP-0285, industries can help prevent these problems and ensure reliable operation of their water systems.
Abstract: This verified PDF contains the full text of NACE RP0285 (2016 revision), the recommended practice addressing identification, monitoring, and mitigation strategies for microbiologically influenced corrosion (MIC) in upstream and midstream oil and gas operations. The document covers mechanisms of MIC, detection methods (including molecular and culture-based techniques), risk assessment frameworks, recommended inspection and monitoring protocols, biocide selection and treatment practices, material selection and protection, case studies, and guidance on data interpretation and recordkeeping. This verified edition includes the official figures, tables, and appendices as published by the issuing organization.
This method uses an external alternating current (AC) power source converted to direct current (DC) via a rectifier. The DC current flows from non-consumable anodes through the soil to the UST. RP0285 provides detailed instructions on sizing rectifiers, managing voltage ripples, and preventing stray current interference on neighboring infrastructure. The Three Acceptance Criteria nace rp 0285 pdf verified
Galvanic systems utilize anodes made of highly active metals, typically magnesium or zinc. Because these metals have a more negative electrochemical potential than steel, they corrode sacrificially to protect the tank.
It is the definitive standard for engineers, corrosion professionals, and UST owners to ensure compliance with environmental regulations regarding tank integrity. Scope of the Standard The standard addresses the following components:

This is arguably the most critical technical section, defining the quantifiable metrics for success. A fundamental criterion is achieving a negative (cathodic) polarized potential of at least 850 millivolts (mV) relative to a saturated copper/copper-sulfate reference electrode (CSE). Another key criterion is achieving a minimum of 100 mV of cathodic polarization . These criteria provide a measurable target for system design and performance validation.
