Quality Control

Accelerated corrosion testing and thickness metrology that turn every normative requirement into verifiable evidence.

VALIDATION

We certify the coating’s effectiveness before delivery and installation on site.

Every batch is validated through specific protocols that account for the type of coating and its operating service conditions.

01

ISO 9227 · ASTM B117

Salt spray chamber

Assesses zinc coatings in an accelerated atmosphere at 35 °C with 5 % NaCl, recording the hours until white or red corrosion appears.

02

ISO 16701 · ASTM G85

Cyclic corrosion

We evaluate the real-world performance of coatings through combined cycles of salinity, humidity, drying and freezing.

03

Automated logging

Thermal cure monitoring

Monitors the baking of zinc and aluminium flake, typically holding 300–320 °C for the validated time to ensure polymerisation and stress relief.

04

ASTM F1470 reference

Sustained load and IHE

Bolt samples harder than 39 HRC are held at 75–80 % of the minimum tensile strength for at least 200 hours. The batch is accepted only if every sample finishes without cracks or fractures.

05

Go / No-Go ring gauges

Thread dimensional verification

Go/No-Go gauging after curing confirms smooth assembly, with no interference from coating build-up and no alteration of the K factor.

Magnetic gauges verify thickness without destroying the part. Visual and dimensional inspection completes the record to ensure coverage, uniformity, thread fit and batch traceability.
