IEC 62368-1 G.13.6.2 and G.4 Coating Scratch Resistance Test Device

The LS-B30 Coating Scratch Resistance Tester is a specialized device for testing the scratch resistance of material coatings. It applies a specific axial force to the test sample using a standardized scratching steel bar, scratching at a specified angle and speed in the forward direction. The device accurately simulates the contact of a sharp tool with the coating, thereby assessing the strength of coatings on easily accessible solid insulating components or printed circuit boards, verifying their resistance to puncture risks, and providing testing conditions that meet relevant requirements for the quality assessment of material coatings.

Standards:

Specification:
• Scratching steel needle: hardened steel needle, tapered end, cone top 40, rounding radius 0.25±0.02mm
• Angle of scratching: The moving plane of the scratching needle is perpendicular to the surface of the test object, and the tilt angle of scratching is 80 degrees ~ 85 degrees.
• Axial force of steel needle during coating scratch resistance test: 10N±0.5N
• Marking length: maximum 140mm
• Translation distance: maximum 200mm
• Stroking speed: 20mm/s±2mm/s (adjustable)

Typical Applications:

• Scratch resistance testing of coatings on easily accessible solid insulating parts of household appliances
• Coating strength verification of insulating parts in similar household appliances
• Scratch resistance testing of printed circuit board surface coatings
• Puncture resistance assessment of insulating coatings for electronic devices
• Quality compliance testing of coatings for materials related to household appliances and information technology equipment
