Abrasion and hardness tests
Abrasion tester - TABER ABRASER 352 G (Typ 5135)
durability against abrasion
- abrasion by friction roller with a defined strength on a rotating sample
- weight loss method, visually evaluation and microscopical abrasion depth determination
Scratch hardness tester - Erichsen Linear tester Modell 249
durability against different surface exposure
- scratch test with different standardized testing tips
- double stroke abrasion tests, crock meter test, MEK test, and solvent respectively wiping test
- testing tips are operating with single- or double stroke and a defined strength on the surface
Pendulum damping tester - Erichsen Modell 299/300
hardness determination of surfaces according to König and Persoz
- evaluation of the damping behaviour of surfaces
- a standardized pendulum is placed on the surface and transferred into vibrations
- if the surface is harder, the vibrations are less damped
Hardness test pencil - Erichsen Modell 318S
determination of the hardness of a surface
- determination of the resistance of a layer or a multilayer system by ingression of a defined weight
- the test pencil ingress to the substrate or to an intermediate layer
Scratch hardness pencil - Erichsen Schmiss / Metal Marking Modell 435
determination of the scratch resistance of a surface
- simulation of “small” scratches on the surface such as coatings
- simulation of “Metal-Marking” (damage of the surface by metal particles)
