SCRATCH HARDNESS TESTER ERICHSEN 413

Various types of scratch tools, ranging from sharp pointed to rounded and flat with sharp-edges are available so that the test can mimic the scratch effects to be allowed for under practical conditions to represent the product properties over as wide a range of conditions as possible.
The SCRATCH HARDNESS TEST ER 413 in this way covers a wide variety of scratch resistance as required for different materials: vehicle or general coatings or plastic surfaces of light switches and push buttons, mobile phone displays, handles, housing components, general displays, vehicle components, vehicle cockpit switches, plastic products in general use, small plastic components (with or without coating), glass, glass coatings, high tech glass coatings and coatings for spectacle lenses (made of glass or plastic) and many other examples.
In today’s world we are surrounded by a very wide range of materials, most being produced industrially.
The surfaces are intended to achieve specific surface qualities but often the manufacturers of many products for the home, car, train, tram, bus, office, etc often do not yet monitor the scratch resistance quality of these surfaces.
The application of the Erichsen Model 413 can in all such cases provide a basis for assurance of the surface quality of these products.
