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 249Durability 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 318SDetermination 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 435Determination 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)
