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

The LS-B30 Coating Scratch Resistance Tester is a precision instrument designed for evaluating the mechanical durability of protective coatings on electrical components. This device applies controlled axial force through a standardized hardened steel needle, executing scratches at specified angles and velocities to simulate tool contact scenarios. It provides quantitative assessment of coating integrity on accessible solid insulating components and printed circuit boards, verifying compliance with international safety standards for puncture resistance.

Standards Compliance:

• IEC 62368-1:2018 – Audio/video, information and communication technology equipment – Safety requirements
• GB/T 4943.1-2022 – 信息技术设备 安全 第 1 部分：通用要求 (Information technology equipment safety – Part 1: General requirements)

Technical Specifications:

• Scratching Needle: Hardened steel with tapered conical end (cone top 40°, rounding radius 0.25±0.02mm)
• Scratching Angle: Needle movement plane perpendicular to test surface with 80°-85° tilt angle
• Axial Force: 10N±0.5N during coating scratch resistance testing
• Marking Length: Maximum 140mm
• Translation Distance: Maximum 200mm
• Stroking Speed: 20mm/s±2mm/s (adjustable)

Typical Applications:

• Scratch resistance evaluation of coatings on accessible solid insulating components in household appliances
• Coating strength verification for insulating parts in similar electrical equipment
• Surface coating durability testing on printed circuit boards
• Puncture resistance assessment of insulating coatings for electronic devices
• Quality compliance testing for coatings on materials used in household appliances and information technology equipment
