AMPP CP3 Technologist study guide
AMPP CP3 Technologist · Work through your exam, one topic at a time.
The AMPP CP3 Technologist credential is an advanced-level certification for coatings professionals who already inspect and want to be recognized for the technical judgment that sits above routine inspection: interpreting specifications, diagnosing coating failures, resolving disputes over surface preparation and application, and advising on material selection. It is aimed at experienced coatings inspectors, project coating engineers, QA/QC leads, and technical service staff in industries such as pipelines, marine, water and wastewater, and industrial facilities. The AMPP CP3 Technologist study guide has 8 sections and about 2,416 words.
01Corrosion Fundamentals and Coating Science
You must be able to explain why a coating protects metal, not just recite that it does. The core mechanism for most barrier coatings is isolating the substrate from electrolyte, oxygen, and ionic species; for zinc-rich or inhibitive systems the mechanism shifts to galvanic or chemical passivation.
333 words, about 2 min02Surface Preparation Standards and Methods
Surface preparation is where most coating failures originate, so questions are dense here. Know the visual standards by name and what each represents: SSPC-SP 1 (solvent cleaning), SP 2 (hand tool), SP 3 (power tool), SP 5/NACE No.
322 words, about 2 min03Coating and Lining Material Types and Selection
You need a working map of generic coating families and where each fits. Epoxies (amine or polyamide cured) give good chemical resistance and adhesion but chalk under UV; polyurethanes offer UV stability and color retention; zinc-rich primers provide galvanic protection; inorganic zinc resists high temperature and solvents but needs a suitable tie coat; phenolics/novolacs handle aggressive acids; silicones handle high temperature; coal tar epoxies resist water immersion but are increasingly restricted.
289 words, about 1 min04Coating Application Methods and Equipment
Application questions test whether you can connect equipment, technique, and film quality. Know air spray , airless spray , conventional spray , brush , and roller , and when each is appropriate.
297 words, about 1 min05Inspection, Testing, and Quality Control
Inspection questions reward precision about what is measured and when . Know surface profile measurement methods (comparator, replica tape, stylus), DFT measurement (magnetic/eddy-current gauges, Type 1 vs.
294 words, about 1 min06Specifications, Standards, and Project Documentation
This domain tests whether you can read and apply a specification rather than rely on memory. Know the structure of a coating specification: scope, referenced standards, surface preparation, materials, application conditions, inspection, and acceptance criteria.
293 words, about 1 min07Safety, Environmental, and Regulatory Requirements
Safety questions test hazard recognition and control, not memorized regulation numbers. Understand hazard communication : labels, safety data sheets, and training.
280 words, about 1 min08Failure Analysis, Troubleshooting, and Remediation
Failure analysis questions present a symptom and ask for the most probable cause and the appropriate remediation. Know the common failure modes : blistering (osmotic, solvent, or gas), undercutting , cathodic disbondment , chalking , cracking and mudcracking , sags and runs , pinholing , dry spray , delamination , and rust staining/spot rusting .
