Frequently Asked Questions

4. Key Distinction: Coated vs. Bare Steel

One of the reasons this standard is so widely cited is that it distinguishes between two very different scenarios:

Coated Tanks (STI-P3): These are newer tanks with a factory-applied coating. The standard allows for lower current output because the coating does most of the work.
Bare Steel Tanks: These are older, rusty tanks. The standard acknowledges that these require significantly more electrical current to protect. It provides specific guidance on how to distribute anodes around a bare tank to ensure the bottom isn't eaten away.

Step 4: Hash Validation (Advanced)

AMPP does not publicly post SHA-256 hashes, but enterprise subscribers can request a checksum from customer service. Compare the hash of your file to the official one.

Why Was RP 0285 Created?

Tank bottoms are uniquely susceptible to corrosion due to:

Poor oxygen availability (leading to differential aeration cells).
High temperatures (heated tanks accelerate corrosion).
Inability to inspect the bottom directly without emptying and lifting the tank.
Variations in soil resistivity and moisture under the tank.

RP 0285 filled a critical gap where pipeline standards (like RP 0169) were inadequate. Corrosion protection : The document provides guidance on

Best Practices for Maintaining Compliance

Always purchase from AMPP directly – The $200–$300 cost is negligible compared to a tank leak.
Store the PDF in a controlled document management system – Restrict access to engineering and integrity teams.
Subscribe to AMPP’s “Standards Update” alerts – Free email notifications when RP 0285/SP0285 changes.
Train your corrosion staff – A verified PDF is useless if the criteria are misinterpreted. Pair the standard with a NACE CP Tester or CP Technician course.
Audit your vendors – If a CP contractor provides a “free” PDF as a reference, request their original purchase receipt from AMPP.
