IEC 60950-1 Clause 2.10.8.4 Automatic Abrasion Resistance Tester for Printed Circuit Abrasion Strength

IEC 60950-1 Clause 2.10.8.4 Automatic Abrasion Resistance Tester – Printed Circuit Abrasion Strength Device

The IEC 60950-1 Clause 2.10.8.4 Automatic Abrasion Resistance Tester is a high-precision, automated testing instrument manufactured by KingPo, designed specifically to evaluate the abrasion strength of printed circuit boards (PCBs). Compliant with IEC 60950-1 Clause 2.10.8.4, this tester creates controlled scratches across five pairs of conducting parts and intervening separations at points of maximum potential gradient, ensuring markings, coatings, and insulation withstand mechanical wear without compromising safety or functionality.

In IT and AV equipment, PCB markings (warnings, symbols, terminals) must remain legible after abrasion. The KINGPO tester addresses this by using a hardened steel pin to apply standardized scratches at precise speed and force, allowing manufacturers, testing labs, and QA teams to verify coating durability and prevent risks like illegible labels or exposed conductors.

This automatic abrasion resistance tester delivers consistent, repeatable results with high traceability, making it essential for regulatory compliance, design validation, and quality assurance in PCBs for servers, routers, power supplies, monitors, and other electronic products.

 Core Role & Purpose

The tester performs automated abrasion on PCBs to check:

• Coating and marking durability under mechanical stress
• No damage at maximum potential gradient points
• Compliance with Clause 2.10.8.4 for printed circuit safety
• Prevention of insulation failure or signal issues

It simulates real-world wear, ensuring long-term PCB reliability.

Professional Construction & Technical Precision

Key features include:

• Steel Pin: Hardened conical tip (40° angle, 0.25 mm ±0.02 mm radius)
• Scratch Speed: 20 mm/s ±5 mm/s
• Force: 10 N ±0.5 N
• Scratch Angle: 80–85°
• Pitch: ≥5 mm apart, ≥5 mm from edges

These ensure accurate, repeatable abrasion strength testing for PCBs.

Primary Use Cases & Business Value

The tester supports key stages:

• R&D and Design Validation — Engineers optimize PCB coatings and markings for abrasion resistance.
• Compliance Certification — Labs generate reports for CE, UL, CB Scheme, CCC submissions.
• Production QC — Manufacturers test batches to ensure consistency and prevent failures.
• Failure Analysis — Investigate abrasion-related defects in returned products.

It helps deliver durable PCBs, shorten certification timelines, and reduce quality costs.

Compliance & Regulatory Assurance

Fully compliant with IEC 60950-1 Clause 2.10.8.4. Aligned with CE, UL, CB Scheme, CCC requirements for IT/AV products. Regular calibration recommended.
