Specify and verify quality control for a plant-applied fusion-bonded epoxy (FBE) external pipeline coating

Steps

1. Confirm the governing application/QC standard is NACE SP0394 (retains its legacy NACE SP prefix under AMPP), 'Application, Performance, and Quality Control of Plant-Applied Single-Layer Fusion-Bonded Epoxy External Pipe Coating,' and check content.ampp.org for current edition status
2. Confirm holiday detection on the finished FBE coating uses the FBE-specific standard NACE SP0490 ('Holiday Detection of Fusion-Bonded Epoxy External Pipeline Coatings of 250 to 760 µm/10 to 30 mils'), not the generic SP0188 procedure, since SP0490 addresses the thickness range and detection technique specific to FBE
3. Confirm cathodic disbondment resistance testing per the referenced ASTM G8 method (or the applicable NACE/AMPP cathodic disbondment test the project spec cites) as part of qualification/QC testing
4. Verify plant DFT, cure (via differential scanning calorimetry or the specified cure-verification method), and adhesion testing frequency against SP0394's QC requirements rather than an ad hoc sampling rate
5. Document coating qualification test results and production QC records together, since SP0394 ties ongoing production acceptance to initial qualification test data
