Common failures & inspection points
Measure with coating thickness gauge (gage) per SSPC-PA2. Example: Jotamastic 90 shall be 100 µm = passed; <75 µm = rework required. Statistical sampling: minimum 20 points/m².
Cross-Hatch-Adhäsionstest (ASTM D3359) durchführen: 6mm Rasterabstände, Klebeband aufreißen. Bewertung: Level 0 = beste Haftung (0% Verlust). Level ≥3 = Schicht-Versagen → Nacharbeiten. Alternativ: Pull-off Test >5 MPa.
Pencil hardness test (ASTM D3363) perform: guide pencil at 45° angle with pressure over surface. Expected for epoxy after 7 days: ≥H (hard). Observe test duration per TDS (typically 24–48h hard-dry, 7 days full cure).
Surface roughness inspect: ISO 8501-1 grade Sa 2½ (medium roughness) or white-metal. Surface roughness: 30–85 µm (ISO 8503-2, fine–medium). Visual + surface roughness gauge (profile gauge) use.
Holiday detector (spark tester for >250 µm; low-volt sponge for <500 µm) guide over entire area systematically. Defects localize and mark with red marking → must be repaired before operation.
IMO PSPC certificate of coating system inspect (ballast tank coatings, COT = cargo oil tank). Salt spray test references (ASTM B117) ≥500 hours for ballast, ≥1000–2000h for heavy marine applications inspect. Certificates: ClassNK, Lloyd's Register.
