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.
