Coating Inspection
Inspection and laboratory sit in the same house. What the field inspector reports on surface preparation and film build can be checked against coating evaluation and testing on the bench, with the cathodic protection division alongside for buried and immersed service.

Overview
TCR Engineering Services Pvt. Ltd., the NABL ISO/IEC 17025:2017 accredited testing house in Navi Mumbai, deploys NACE/AMPP-qualified coating inspectors for field and shop coating inspection across India and the GCC, working alongside the laboratory's coating evaluation capability and the cathodic protection division.
What coating inspection is
TCR deploys AMPP/NACE-qualified coating inspectors for field and shop coating inspection across India and the GCC, backed by the laboratory's coating evaluation capability and the cathodic protection division in the same house.
Senior TCR paint inspectors are qualified BGas and NACE certified, and the group bench carries AMPP/NACE Coating Inspector (CIP) Level 2 and Level 3 personnel, with FROSIO Inspector Level III available in the GCC through TCR Arabia. What the field inspector reports on surface preparation and film build can be checked against coating evaluation on the bench.
Through the coating lifecycle
Field inspection covers the coating lifecycle: surface preparation, primer, intermediate, topcoat, holiday detection, and post-cure dry-film and wet-film thickness verification.
Inspectors verify the blasting and coating materials, the blasting and coating equipment, the temperature and humidity, the surface condition, and the application procedure. The team is equipped with wet-paint thickness gauges, dry-paint film thickness gauges, holiday detectors, a hygrometer with dew-point calculator, and a metal-surface thermometer. Records capture materials control and identification, climatic and surface conditions, abrasive details and the abrasive or wire-brush standard, coating and application-procedure detail, equipment calibration, and inspection results.
Governing standards
Field capability is anchored to the AMPP/NACE Coating Inspector framework and read against the ISO 12944 protective-coating series.
| Field capability | Standard |
|---|---|
| Surface preparation visual standard | SSPC-VIS 1, ISO 8501-1 |
| Anchor profile | ASTM D4417, ISO 8503 |
| Dust contamination | ISO 8502-3 |
| Soluble salt contamination | ISO 8502-6, ISO 8502-9 |
| Wet film thickness | ASTM D4414 |
| Dry film thickness | ASTM D7091, ISO 2808 |
| Holiday detection | NACE SP0188 |
| Adhesion (field) | ASTM D3359 (cross-cut), ASTM D4541 (pull-off) |
| Cure verification | DSC, FTIR, Persoz hardness |
The laboratory complement
Field findings can be confirmed on the bench, where the laboratory evaluates coating systems in full.
Laboratory evaluation covers cross-cut adhesion per ASTM D3359, pull-off adhesion per ASTM D4541, coating thickness per ISO 2808 and ASTM D7091, cathodic disbondment per ASTM G8, and salt-spray resistance per ASTM B117, with SEM and EDS for galvanised coatings, FTIR and DSC for epoxy coatings, and TGA for bituminous coatings. Elastomeric coating performance under sour-service exposure is a Shell-approved capability. The cathodic protection division sits alongside for buried and immersed service.
Personnel
Coating inspection is delivered by credentialled inspectors.
The bench carries AMPP/NACE Coating Inspector (CIP) Level 2 and Level 3 inspectors and BGas-certified paint inspectors, with FROSIO Inspector Level III personnel in KSA through TCR Arabia. Inspection is delivered alongside TCR's third-party inspection and source inspection service lines.

Frequently asked questions
What qualifications do TCR coating inspectors hold?
The bench carries AMPP/NACE Coating Inspector (CIP) Level 2 and Level 3 inspectors and BGas-certified paint inspectors, with FROSIO Inspector Level III personnel in KSA through TCR Arabia.
What does a field coating inspector check?
The inspector verifies surface preparation, the blasting and coating materials and equipment, temperature and humidity, surface condition, the application procedure, holiday detection, and post-cure dry-film and wet-film thickness.
Which standards govern coating inspection at TCR?
Surface preparation runs to SSPC-VIS 1 and ISO 8501-1, anchor profile to ASTM D4417 and ISO 8503, dry film thickness to ASTM D7091 and ISO 2808, holiday detection to NACE SP0188, and field adhesion to ASTM D3359 and ASTM D4541, referenced to the ISO 12944 series.
Can field findings be confirmed in the laboratory?
Yes. The same house runs coating evaluation on the bench, including cross-cut and pull-off adhesion, cathodic disbondment per ASTM G8, and salt-spray resistance per ASTM B117, with the cathodic protection division alongside for buried and immersed service.
