Using precision tips, the Taber Multi-Finger Scratch/Mark Tester is used to measure the susceptibility of material surfaces to scratches, marring, tears, and other similar physical damage not classified as normal wear and tear.
Characteristics:
The samples are fixed to a pneumatically actuated platform. Five independent spline shaft fingers with varying weights exert a constant vertical load on the test sample as it travels under the interchangeable scraping tips. The spline shaft fingers are mounted on a rigid gantry platform. Support rests allow the operator to secure individual shafts in a rest position, allowing testing of non-standard width specimens.
The 'five finger' scratch tester has been popular in the automotive industry for testing smooth or grained plastics commonly used in ornamentation or moldings. Useful for quality control as well as material or product development, the multi-finger scratch/mark tester is ideal for the evaluation of plastics, rigid organic materials, paints and coatings, soft metals, linoleum and many more.Technical data LP-463DD-18-01 (Chrysler) Scratch and wear resistance of automotive plastics - Determination of This procedure describes the method for determining the scuff and scuff resistance of colored molded automotive plastics using a linearly oriented, single-pass, multi-scratch device. This method is appropriate in evaluating the wear resistance of colored molded automotive thermoplastics used for interior or exterior trim or trim applications. PF-10938 (Chrysler) Scratches and marks: resistance of colored molded plastic components This standard establishes minimum requirements for engineering acceptance of scratch and scuff resistance of colored molded plastic parts. The ultimate goal is to produce molded plastic parts that resist scratching and deterioration and therefore do not detract aesthetically from the vehicle and/or hinder the quality appearance of the vehicle. Additionally, this standard is to verify that after the molding process the molded stresses do not adversely affect the scratch or deterioration resistance of the material. BN 108-13 (Ford) Scratch resistance WITHDRAWAL: This procedure is used to determine the scratch resistance of plastic or other material surfaces under standard conditions. [replaced by BO 162-01] BO 162-01 (Ford) Scratch and wear resistance This procedure is used to determine the scratch, bleach, and mar resistance of plastic or other material surfaces under standard conditions. GMN 3943 (General Motors) Scratch and wear resistance of plastics, five-arm test WITHDRAWAL: This test method describes a test device and procedure for evaluating the scratch and scuff resistance of plastics. [replaced by GMW 14698] GMW 14698 (general motors) Scratch resistance of organic coatings and self-adhesive sheets This standard will be used to determine the scratch resistance of organic coatings applicable to single or multi-layer systems applied to metallic or polymeric substrates and self-adhesive sheets. NES M0159 (Nissan) Test method for scratch resistance of polypropylene resin interior parts This NES specifies the methods for testing the scratch resistance (hereinafter referred to as test methods) of automotive interior resin parts (hereinafter referred to as parts). These test methods are specifically applied to parts made of polypropylene (hereinafter referred to as PP) and its composite materials (hereinafter referred to as PPC) of resin inner parts. These test modes should not be applied to a painted part or surface-coated plastic part.
