• Glossary
  • ABREX®
    Simulation of soft-chemo-mechanical hand abrasion (ABREX®-Abrasion)
  • BMW GS 97034
    BMW Specification for all suppliers for surface test of motor vehicle interior materials
  • Crockmeter
    determine the amount of color transferred from textile materials (such as fabric, carpeting, yarn and leather) to other surfaces by rubbing
  • Deformation
    changes in an objects shape or form due to the application of a force Depending on the type of material, size and geometry of the object, and the forces applied, various types of deformation may result, for example, elastic, permanent
  • Durability
    A property of the resistance against wear, abrasion, decay
  • Dyna-SPA®
    High dynamic scratch, punch and abrasion tester
  • Effective Contact area
    When two objects touch, a certain portion of their surface areas will be in contact with each other Also usable for haptic evaluation  Because of the shape of the human finger tip, we only can perceive the uppermost microns of an object s surface
  • Elasticity
    Elasticity is the ability of a body to resist a distorting influence or stress and to return to its original size and shape when the stress is removed
  • Fingernail scratch
    a mark of abrasion on a surface by human fingernail
  • Fingerprint affinity
    The tendency that human fingerprint is imprinted onto the surface of the product
  • Fracture
    This type of deformation is also irreversible A break occurs after the material has reached the end of the elastic, and then plastic, deformation ranges At this point forces accumulate until they are sufficient to cause a fracture
  • Frame
    a structure supporting or containing something
  • Friction
    Friction is the force that makes it difficult for things to move freely when they are touching each other
  • Hand abrasion
    A special abrasion between the product surface and human hand which has chemical environment and mechanical rubbing motion Is simulated by ABREX® (ABREX®-Abrasion)
  • Haptics
    Form of interaction involving touch and the process of recognizing objects through touch
  • Hardness
    Determination of the surface’s or coating’s resistance against an applied deforming force For this, a sharp or blunt stylus is usually facilitated, depending on the inspected material
  • Height sectional cut
    Analysis of a 3D Topography Cutting the surface according to different heights into various planes
  • Limpness
    losing stiffness or firmness, as of substance, fiber, structure, or bodily frame
  • Macrostructure
    the gross structure of an object as made visible to the naked eye
  • Metal fatigue
    Deformation mechanism occurring primarily in ductile metals
  • Plastic deformation
    Irreversible deformation
  • Plasticity
    describes the deformation of a (solid) material undergoing non-reversible changes of shape in response to applied forces
  • Scratch quantification
    counting and measuring the scratches on the surface that maps human observations and illustrate with a set of numbers
  • Soiling affinity
    The tendency that the soil is transferred and adheres onto the surface of the product
  • Surface
    the outer boundary of an artifact or a material layer constituting or resembling such a boundary;
  • Taperader®
    Micro-Kalotest with Taperader® for quick, mobile abrasion measurement (destruction free)
  • TRACEiT®
    3D Profilometer Visiometer for fast 3D measurement of topography and roughness
  • Tribometer
    an instrument that measures tribological quantities, such as coefficient of friction, friction force, and wear volume, between two surfaces in contact
  • Universal Surface Tester®
    UST®: Universal Surface Tester® for measuring elastic and plastic deformation behavior, roughness, haptics, hardness, damping, creeping and recovery (3D possible)
