The RAL Quality Mark (Gütezeichen) of GSK

From material testing and process parameters to coating tests, everything in the production process is monitored and logged in specified and comprehensive self-testing. Furthermore, there are annual unannounced external inspections by a testing institute. All testing is carried out according to the GSK’s current Quality and Inspection Regulations and Implementation Regulations.

All tests confirm the high quality standards of epoxy powder coating. The compulsory external inspections must be undertaken by recognised and neutral institutes. The unannounced spot checks are carried out by independent testing institutes appointed by the GSK’s Executive Committee.

These are currently the Hannover-based Material Testing Institute for Materials and Manufacturing Engineering (MPA) and the Research Institute for Precious Metals and Metal Chemistry (fem) based in Schwäbisch Gmünd. The test reports of the MPA and the fem certify that the requirements are adhered to.
