Automatic Scratch Tester
The Automatic Scratch Tester is designed for evaluating the hardness and friction performance of coatings on a wide range of materials and products. It is suitable for electronics, household appliances, metal coatings, decorative materials, and synthetic leather, as well as mobile shells, MP3/MP4 shells, and laptop shells. The instrument measures coating hardness and resistance to friction, providing reliable data for quality control and material research.
Application
(1) Testing hardness and scratch resistance of coatings on electronics and digital device shells, including mobile s, MP3/MP4 players, and laptops.
(2) Evaluating friction performance of household appliance surfaces.
(3) Testing wear and scratch resistance of metal coatings and decorative materials.
(4) Assessing durability of synthetic leather and similar materials under repeated friction.
(5) Quality control in coating, paint, and material manufacturing.
(6) Research and development of new coatings or surface treatment processes.
Standards
(1) ASTM D3363 – Standard Test Method for Film Hardness by Pencil Test.
(2) ASTM D6037 – Standard Test Method for Wet Abrasion Resistance of Organic Coatings.
(3) ISO 1518-1 – Paints and varnishes – Determination of scratch resistance – Part 1: Method using a scratching stylus.
(4) ISO 1518-4 – Paints and varnishes – Determination of scratch resistance – Part 4: Instrumented method.
(5) BS 3900:E2 – British Standard for scratch testing of coatings.
(6) BS EN 13523-12 – European standard for determination of scratch resistance of coatings.
Features
(1) Adjustable test load from 50g to 1000g for precise force application.
(2) Adjustable reciprocating friction stroke from 10mm to 60mm.
(3) Variable test speed from 5 to 60 times/min with LCD display feedback.
(4) Digital friction counter (0–9999) with power-off memory function.
(5) Supplied calibrated load weights (50g, 100g, 200g, 300g, 500g, two of each).
(6) Equipped with friction media holders for cotton cloth, erasers, and Chinese 2B pencils.
(7) Reciprocating mechanism provides controlled back-and-forth motion of the friction medium.
(8) Compact design suitable for laboratory use.
(9) Facilitates objective assessment of coating durability and scratch resistance.

Test Procedures
(1) Place the sample securely on the test stage.
(2) Select test parameters: load, stroke, speed, and friction medium.
(3) Start the reciprocating motion and monitor real-time test progress.
(4) Count and record the number of cycles until specified wear or scratch occurs.
(5) Optionally capture observations for quality documentation.
(6) Complete the test and remove the sample safely.
Maintenance Information
(1) Keep the friction media and holders clean to avoid contamination.
(2) Regularly inspect the reciprocating mechanism for wear or misalignment.
(3) Calibrate the load and stroke parameters periodically for accuracy.
(4) Avoid exposure to moisture and corrosive substances.
(5) Ensure stable power supply and prevent electrical overload.
(6) Handle the instrument gently during installation or relocation to protect mechanical components.
