Common failures & inspection points
Visual: check coating for dryness; tacky test (touch); odor test; for H4R: up to 9 h permissible at <80°F/<60% r.H. (otherwise oven/discard); document with moisture meter
Surface inspection: check coating for cracks/breaks; check color/gloss (discoloration=moisture); compare storage duration; batches >6 months dry before use; discard defective batches
Check documentation: certificate number DNV/ABS/Lloyd's on container; AWS/ISO classification (e.g. E7018 H4R M 3 YH5); review batch papers; query DNV Approval Finder; check certificate expiration date; reject batches <approval date
Etiketten sichtbar/lesbar: Chargennummer, Verfallsdatum, Lagerdatum, Lagerort, Temperatur/Feuchte-Protokoll; Materialtestzertifikate (MTR) verfügbar; Schweißprozedur (WPS) + Schweißerqualifikation (WQR) dokumentiert; Logbuch Ofen-Ein-/Auszeiten führen
View oven protocol: check achieved temperature (E7018: 450-500°C, observe tolerance); holding time from reaching nominal temperature; holding temperature ~150°C after cooling; demonstrate thermometer calibration; temperature data logger; avoid over-drying (coating breaks)
Storage conditions on site: temperature, air humidity (hygrometer), ventilation, salt spray protection; container integrity (dents/scratches=rust risk); location on ship: near engine room (<50°C ideal); seal containers after opening; compare storage duration versus expiration date
