Automatic Scratch Tester
Model No. :
Model No. : 2801
Brand : BEVS
The BEVS Automatic Scratch Tester is an advanced instrument used to evaluate the scratch resistance performance of single or complex coating systems, particularly on insulated color-coated sheets. By precisely traversing a tungsten carbide hemispherical stylus across the sample under a defined load, the machine objectively determines whether the coating fails or identifies the maximum load it can withstand without damage. This automated process removes operator variability, ensuring objective quality control data.
- Evaluates coating scratch resistance
- Tungsten carbide stylus application
- Delivers objective quality data
− Features
- Digital Touch-Screen Operation: Features a large LCD touch-screen design, allowing for intuitive setup and easy digital control of all testing parameters.
- Precise, Consistent Speed: Operates at a fixed scratch speed of across a defined stroke length of , guaranteeing standardized test conditions and reproducible results.
- Real-Time Graphical Monitoring: Capable of displaying the scratch trace graphically in real-time on the screen, providing immediate visual feedback on the testing procedure.
- Objective Pass/Fail Indication: For conductive substrates, the system can display the test result as a direct “OK” or “NG” (Not Good) indicator, simplifying quality control decisions.
- Durable Indenter: Utilizes a high-hardness tungsten carbide hemispherical stylus with a diameter, ensuring long-term durability and consistency in applying the scratching force.
- Adjustable Work Platform: Includes an adjustable work platform for convenient and precise sample positioning, accommodating metallic test panels up to (L x W x H).

Software
Integrated Digital Control Interface
The BEVS Automatic Scratch Tester utilizes an integrated digital control system accessible via its touch screen. This allows the operator to control the testing procedure, set parameters, and monitor the test visually with a real-time graph of the scratch path. For certain applications (conductive substrates), the software provides an immediate pass/fail indication, streamlining result interpretation.
FAQs
Which international standards does the Automatic Scratch Tester comply with?
The BEVS Scratch Tester is designed to meet the specified test methods for film scratch resistance as defined by international standards, including ISO 1518 and BS 3900.
What is the maximum distance the scratching stylus travels?
The instrument operates with a defined maximum stroke length of , ensuring a consistent test area across all samples.
How does the Automatic Scratch Tester determine a “scratch” failure?
Failure is determined by whether the tungsten carbide hemispherical stylus scratches through the coating system to the substrate when applied with a set load. For conductive substrates, the system can use electrical contact to automatically signal a failure point.
What material is the scratching tip made from?
The standard stylus is constructed from high-hardness tungsten carbide and features a hemispherical tip, chosen for its durability and resistance to wear.
How does the instrument help with Quality Control decisions?
By providing real-time graphical feedback and a direct “OK” or “NG” result (for conductive panels), the instrument offers an objective and immediate assessment of the coating’s durability, eliminating subjective visual judgment.
