Multi-Finger Scratch / Mar Tester 710


The TABER® Multi-Finger Scratch / Mar Tester - Model 710 is used to measure the relative resistance or susceptibility of a material surface to scratching, marring, gouging, scraping, engraving and other similar physical damage not classified as ordinary wear. Based on the apparatus described in popular automotive specifications, the instrument is commonly referred to as a five-finger (five-arm) scratch & mar tester and most often used to evaluate plastics.

Features

top
  • Pneumatically driven platform to which the test specimen is mounted moves in a linear fashion, and is operated by a control knob for single or multiple pass testing.
  • An electronic timer displays the rate of speed, which can be controlled by reducing or increasing air pressure.
  • A gantry supports five independent splined-fingers, which provide a constant, vertical load on interchangeable scratch tips.
  • The gantry system includes a handle to raise and lower the arms. In addition, five support rests are incorporated to allow one or more arms to be moved to an upright, rest position such that the arm does not contact the specimen during testing.
  • Individual weights of varying loads mount to the top of each arm finger to exert a standard force on the surface of the test material.
  • Weight set of 2N, 3N, 4N, 5N, 6N, 7N, 10N, 15N and 20N loads included
  • Although flat specimens up to 22mm thick are normally tested, the 'free-floating' arms fingers enable you test slightly contoured specimens provided they are rigid or adequately supported.
  • A spring-loaded specimen holder is standard and can be mounted to the end or side of the moveable platform for greater flexibility. To mount contoured specimens, two specimen hold-down clamps are provided.
  • Set of five 1.0mm diameter hemisphere Scratch Tips and 7.0mm diameter hemisphere Mar Tips. Both include a precision tungsten carbide ball mounted to the contact end.

Technical Data
Test Method Reference Test Method Title Test Method Scope
LP-463DD-18-01 (Chrysler) Scratch and Mar Resistance of Automotive Plastics - Determination of This procedure describes the method for determining the scratch and mar resistance of molded-in-color automotive plastics by use of a linearly-oriented, one-pass, multifingered scratching device. This method is appropriate in the evaluation of mar resistance of molded-in-color automotive thermoplastics used for interior or exterior in ornamentation or trim applications.
PF-10938 (Chrysler) Scratch and Mar - Resistance of Molded-In- Color Plastic Components This standard establishes the minimum requirements for engineering acceptance of scratch and mar resistance of molded-in-color plastic parts. The ultimate objective is to produce molded plastic parts which resist scratching and marring and thus are not aesthetically detracting from the vehicle and/or hinder the quality appearance of the vehicle. Additionally, this standard is to verify that after the molding process that molded-in stresses are not adversely affecting the resistance to scratching or marring of the material.
BN 108-13 (Ford) Resistance to Scratching WITHDRAWN - This procedure is used to determine the resistance to scratching on surfaces of plastic or other materials under standard conditions. [superseded by BO 162-01]
BO 162-01 (Ford) Resistance to Scratch and Mar This procedure is used to determine the resistance to scratching, whitening and marring on surfaces of plastic or other materials under standard conditions.
GMN 3943 (General Motors) Scratch and Mar Resistance of Plastics, Five Arm Test WITHDRAWN - This test method describes a testing device and procedure for evaluation of the scratch and mar resistance of plastics. [superseded by GMW 14698]
GMW 14698 (General Motors) Scratch Resistance of Organic Coatings and Self- Adhesive Foils This standard shall be used to determine the scratch resistance of organic coatings applicable to single or multiple coat systems applied onto metallic or polymeric substrates and self-adhesive foils.
NES M0159 (Nissan) Testing Method of the Scratch Resistance of Interior Polypropylene Resin 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 applied specifically to the parts made of polypropylene (hereinafter referred to as PP) and its compound materials (hereinafter referred to as PPC) of interior resin parts. These test modes shall not be applied to a painted portion, or a surface coated plastic part.
