ISO 12137:2011 Scratch Resistance Tester is used to evaluate the scratch resistance of surfaces on electronic information equipment, household appliances, coatings, and plastic materials. The instrument applies a constant or variable load to the sample surface via a scratch needle, forming scratches under controlled movement distance and speed conditions. This enables quantitative assessment of material surface hardness, abrasion resistance, and brittleness. It meets industry standard testing requirements for coatings, films, plastics, and metal surfaces.

The stylus applies a constant or variable load to the sample surface, moving at a set distance and speed to form a scratch. By observing changes in scratch width, depth, or resistance, it quantitatively evaluates the scratch resistance and scratch hardness of coatings, plastics, and metal surfaces. Continuous weights simulate dynamic scratching conditions with load variations during actual use, while constant-load weights are used for basic scratch hardness testing. Optional software analysis further quantifies surface fracture load and friction force.
Operating Instructions:
Sample Mounting and Fixing: Ensure samples are securely fixed, flat, and free of warping.
Scratch Tip and Weight Configuration: Select scratch tip radius and constant/continuous weight combination per test standards.
Safety Precautions: Activate safety guard to prevent operator hand contact with scratch tip.
Select motion mode: Single-pass mode for fixed-distance scratch testing; reciprocating mode for durability evaluation.
Adjust speed and stroke: Set movement speed and stroke length per standards or experimental requirements.
Temperature and humidity control: Operate between 0–50°C and below 85% RH to prevent condensation from affecting test accuracy.
Test Procedure:
Install the stylus and load weights, confirming the safety cover is in place.
Secure the sample in the workbench fixture and adjust the horizontal position.
Set the motion mode (single or reciprocating), movement speed, travel distance, and cycle count.
Start the instrument to create scratches on the sample surface with the stylus.
After testing, observe scratch width and depth or analyze scratch resistance data using software.
Record test results according to standard requirements and repeat experiments to verify consistency.
1. What materials can you evaluate using this scratch resistance tester?
You can test coatings, paint films, plastics, rigid organic materials, and soft metal surfaces used in electronics, appliances, and automotive components.
2. What is the difference between constant load and continuous load testing?
Constant load testing applies a fixed force throughout the scratch, while continuous load testing simulates gradually changing loads to evaluate surface fracture behavior under dynamic conditions.
3. Can you perform durability testing with repeated scratching?
Yes. The reciprocating mode allows repeated scratch cycles, making it suitable for durability and wear resistance evaluation.
4. How do you select the appropriate stylus radius?
You choose the stylus radius based on material hardness, coating thickness, and applicable test standards or internal specifications.
5. Is software required for standard testing?
Software is optional. Basic scratch resistance testing can be completed visually or with measurement tools, while software enables advanced quantitative analysis.
