Quality
Kamphuis Nijverdal specializes in performing quality tests in the coating industry. These tests are performed to verify whether the product and its environment meet strict requirements.
We possess over specialists and equipment to perform and report tests ourselves. If a customer requires a NACE-inspector, we involve a third party based on experience gained with external parties. An inspection report (English/Dutch) is the result of these inspections, according to high standards of the end user.Wij beschikken over specialisten en apparatuur om testen zelf uit te voeren en te rapporteren. Indien door de klant een NACE-inspecteur wordt geëist, schakelen wij een derde partij in op basis van opgedane ervaringen met externe partijen. Resultaat van deze inspecties vormt een inspectierapport (Engels-Nederlands) volgens hoogwaardige eisen van de eindgebruiker.
We work according to NEN-EN-ISO 12944. This is an international standard for corrosion protection of steel structures by protective paint systems. NEN-EN-ISO 12944 can be subdivided into:
- Part 1 – General introduction
- Part 2 – Classification of environments
- Part 3 – Design considerations
- Part 4 – Types of surface and surface preparation
- Part 5 – Protective paint systems
- Part 6 – Laboratory performance test methods and associated assessment criteria
- Part 7 – Execution and supervision of paint work
- Part 8 – Development of specifications for new work and maintenance
- Part 9 – Protective paint systems and laboratory performance test methods for offshore and related structures
