Testing of surface treatment
A distinction is made between treated and untreated surfaces. Treated surfaces are tested, whilst untreated surfaces are not.
Surface treatment
Treated surfaces are surfaces that have been varnished or coated with oil, oil/wax or just wax, giving a surface finish similar to varnish.
Untreated surfaces include oil or wax treatments which penetrate the wood and do not leave a film on the surface.
The durability of surfaces is tested in accordance with the following standards
- Water and grease: EN 12720, ISO 4211
- Grease + scratches: NS 8058, DS 2176, SS 8381122
- Scratching: NS 8057, SS 839117
- Alcohol (48%) and coloured liquid (coffee): EN 12720, ISO 4211
- Dry heat 85 degrees Celsius: EN 12722, ISO 4211-2
- Heat on a worktop with cooker 180 degrees Celsius: NS 8061
- Dry heat on edge 85 degrees Celsius: NS 8061
- Water on edge (kitchen only): NS 8062, DS 2175, SS 839120.
Durability of the surface is tested in accordance with: NS-EN 12720, NS-EN 12722, NS 8057 and NS 8058
- Treated surfaces are surfaces that have been varnished or coated with oil, oil/wax or just wax, giving a surface finish similar to varnish.
- Untreated surfaces include oil or wax treatments which penetrate the wood and do not leave a film on the surface.
- The surface is tested with regard to resistance to various types of liquids and stresses: water, grease, coloured liquid (coffee), dry heat, grease in scratches, scratching of the surface. The subframe is tested for water and grease on the varnish surface.
- On domestic furniture the surfaces of desktops, legs, frames and pedestals on all types of furniture are tested. The seat, backrest and armrests of all sitting furniture are also tested. All external surfaces, shelves, bases, etc. of storage furniture are tested. In order to obtain mobelfakta.no approval, strict requirements concerning what the surface must tolerate must be met and the surface must be tested with regard to various types of liquid (water, grease, coffee, alcohol), as well as scratching, dry heat, heat on edge and water on edge. During the test, the surface will be subjected to various types of loading over time.
- Desktops must tolerate both water and grease for 24 hours and alcohol for one hour without any visible change. Worktops must tolerate contact with alcohol for six hours without any visible effect.
