IEC 60745-1 6mm Steel Ball

IEC 60745 6mm Steel Ball for Hand-Held Electric Tool Testing is a specialized safety test tool designed to verify whether hand-held motor-operated electric tools prevent the entry of small objects—critical for avoiding internal component damage or electric shock risks. Fully compliant with Clause 8.2 IEC 60745 , it’s made of high-grade stainless steel for durability and precise dimensional accuracy. Its smooth, burr-free surface ensures consistent testing results, as it mimics real-world small objects that might accidentally come into contact with tools. Lightweight yet robust, it’s essential for manufacturers, labs, and certifiers validating the protective performance of hand-held electric tools.

Specifications:
• Diameter: 6mm (±0.05mm tolerance; meets IEC 60745-1 small object entry test requirements)
• Material:  304 stainless steel (corrosion-resistant, wear-proof; maintains dimensional stability over repeated use)
• Surface Finish:  Polished (Ra ≤ 0.8μm; no burrs or sharp edges to avoid tool enclosure damage during testing)
• Weight:  Approximately 0.9g (calculated based on 7.85g/cm³ stainless steel density; ensures consistent handling)
• Functional Purpose:  Verifies tool enclosures’ ability to prevent the entry of 6mm-diameter small objects (per safety standards)
• Dimensional Consistency:  100% inspected for diameter tolerance; rejects units outside ±0.05mm range

Test Procedures:
• Inspect the steel ball for scratches, deformation, or rust; confirm diameter meets 6mm ±0.05mm specs.
• Power off the hand-held electric tool under test and secure it on a flat, stable surface.
• Identify potential entry points (e.g., vent gaps, switch openings, tool housing seams).
• Place the steel ball gently on each entry point; apply light, steady pressure (simulating accidental contact).
• Check if the steel ball enters the tool’s internal cavity (via visual inspection or disassembly if needed).
• Record results to confirm compliance with safety standards.

Applications:
• Safety testing of corded hand-held electric tools (e.g., electric drills, orbital sanders) per IEC 60745-1 Clause 8.2.
• Compliance checks for cordless hand-held tools (e.g., lithium-ion angle grinders, jigsaws) to meet UL 60745-1 requirements.
• Quality control during production of hand-held woodworking tools (e.g., circular saws, planers) to ensure enclosure.
• Third-party certification testing (e.g., CE, UL, CSA) for hand-held electric tools seeking global market entry.
• Pre-shipment verification of industrial-grade hand-held tools (e.g., concrete breakers, wire strippers) to validate small object protection.
