It defines industry-accepted measurements to verify if a tank is protected, most notably the -850 mV (CSE) polarized potential criterion.

The document has evolved through several iterations to keep pace with modern electrochemical engineering and regulatory frameworks.

What is the of your underground storage tanks?

The standard underwent major revisions to include more specific criteria for different materials, such as bare and coated mild steel.

NACE RP0285 splits corrosion control into actionable engineering phases. A verified PDF copy contains detailed sections covering the following technical pillars: 1. Corrosion Criteria and Testing This link or copies made by others cannot be deleted

For CP systems to work effectively, the target steel must be electrically continuous (all parts connected), while simultaneously isolated from foreign structures (like utility lines, grounding grids, or concrete rebar) that would steal the protective current. NACE RP0285 outlines testing methodologies to verify isolation joints and dielectric unions. 6. Regulatory Alignment: EPA and NACE RP0285

(officially SP0285 ) is a foundational industry standard for the external corrosion control of underground storage tank (UST) systems using cathodic protection. First approved in 1985 and significantly revised in 2002 as a "Recommended Practice" (RP), it has since been updated to a "Standard Practice" (SP), with the latest active version reaffirmed by the Association for Materials Protection and Performance (AMPP) in 2021.
