- 2. 1 Features 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 re- ferred to as a five-finger (five-arm) scratch & mar tester and most often used to evaluate plastics. 1. Precision instrument measures damage to surfaces not classified as ordinary wear. Using precision tips, the Taber Multi-Finger Scratch/Mar Tester is used to measure the susceptibility of material surfaces to scratching, marring, gouging, and other similar physical damage not classified as ordinary wear. 2. Design based on five-finger scratching device described in automotive specifica- tions. Specimens are secured to a pneumatically driven platform. Five independent spline-shaft fingers with varying weights exert a constant, vertical load on the test specimen as it travels under interchangeable scratch tips. Spline-shaft fingers are mounted on a rigid gantry platform. Support rests allow the oper- ator to secure individual shafts in a rest position, permitting the testing of nonstandard width samples. 3. Test a wide range of products. The ‘five-finger’ scratch tester has been popular in the automotive industry for testing smooth or grained plastics commonly used in ornamentation or trim. Useful for quality control as well as materi- al or product development, the Multi-Finger Scratch / Mar Tester is ideal for evaluating plastics, rigid organic materials, paints and coatings, soft metals, linoleum, plus many others. www.qinsun-lab.com info@qinsun-lab.com Standards Ford BN 108-13 ： Resistance to Scratching General Motors DMN3943 Danmler-Chrysler LP-463DD-18-01：Automotive standards Stable Reliable Consistent Introduction
