Measured by documenting at least 100 mV of cathodic polarization decay between the structure and the reference electrode. Why You Need a Verified PDF Standard
The standard is divided into specific operational and design areas to ensure comprehensive protection:
NACE RP0285, titled Corrosion Control of Underground Storage Tank Systems by Cathodic Protection , establishes the minimum requirements for the design, installation, operation, and maintenance of cathodic protection (CP) systems. It serves as a benchmark for corrosion engineers and UST operators worldwide. The standard specifically covers:

The 2011 revision is the version you want. For instance, the is described as a "Bestseller!" on the official store and is frequently referenced as the latest edition. Some sources have noted the 2011 version as "Current", while others list it as "Withdrawn" due to the complexities of its lifecycle within global standards databases.
: Stop environmental contamination before it begins.
Corrosion presents a severe threat to underground storage tank (UST) systems. The National Association of Corrosion Engineers (NACE) developed NACE RP0285 to address this specific issue. This standard provides guidelines for protecting buried metallic structures from rust and degradation. Measured by documenting at least 100 mV of
Environmental protection agencies use current NACE criteria during routine facility inspections. Your testing procedures must exactly mirror the official verified standard text. Where to Secure an Official, Verified PDF
This comprehensive article explains what NACE RP 0285 covers, why verification matters, the risks of using unverified PDFs, and the only legitimate methods to obtain a verified copy.

If a UST leaks and causes environmental damage, regulatory bodies will audit your maintenance records. Presenting data based on an unverified or obsolete standard can lead to heavy fines, voided insurance policies, and legal liability. Compliance Audits

RP 0285 remains active. While SP0169 (Control of External Corrosion on Underground Metallic Piping) is broader, RP 0285 is specifically for UST systems and includes tank-specific coating and stinger anode details not found elsewhere.
