Specifications, Standards, and Project Documentation
What the exam expects
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. Understand the difference between a performance specification (states required outcome) and a prescriptive specification (states products and procedures).
Recognize key organizations and their roles: SSPC, NACE/AMPP, ISO, ASTM, and API for tanks and pipelines. Know the purpose of a coating data sheet (mix ratio, pot life, DFT per coat, recoat window, cure time) and a safety data sheet. Understand submittals, pre-job conferences, daily reports, nonconformance reports, and as-built documentation.
Traps
- Treating a manufacturer's data sheet as overriding a project specification; the specification governs unless it explicitly defers.
- Confusing a standard's number with its content - know what SP 10 or PA 2 actually address.
- Assuming a referenced standard applies at its latest edition when the specification pins a specific year.
- Overlooking that acceptance criteria must be defined before inspection, not after.
Rule of thumb
When documents conflict, the order of precedence in the contract governs; typically the project specification outranks referenced standards, which outrank manufacturer literature unless the specification says otherwise.
Worked example
A data sheet says recoat within 24 hours; the specification requires surface preparation before recoating after 12 hours. The specification controls, and the applicator must prepare the surface before the next coat.
