Kiwa, DVGW/KTW and WICS Assessment Guidelines

Kiwa, DVGW and WICS are independent organizations that provide certification on high quality level. Coatings used for the production or transportation of drinking water need to have a Kiwa, DVGW/KTW or WICS certificate. We are fully certified for processing coatings used in the drinking water sector. To guarantee a high level of quality, our coating processes are audited twice a year by Kiwa.
We also supply various coatings for the food- and pharmaceutical industries that comply with the European standards and directives as well as those of the Food and Drugs Administration (FDA).

Save on time and costs

Kersten coating technology’s processes are certified by Kiwa, an independent organization that provides certifications in the Netherlands. This  means that we can carry out the inspections on suitability of coatings (BRL-K758) and the application of products certified by Kiwa, DVGW/KTW and WICS such as Rilsan® and Resicoat®  without needing consultation of third parties. This will save you both time and money.
