IEC/EN 60950 12mm Hemispherical Hard Rod

IEC 60950-1 Figure 2C 12mm Hemispherical Hard Rod is a specialized test tool for verifying protection of TNV (Telecommunication Network Voltage) circuits in IT and audio/video equipment. Compliant with IEC/EN 60950-1 Figure 2C and UL 6500 Figure B.1 , it features a 12mm diameter conductive rod (80mm long) with a precision hemispherical tip, plus a 50mm diameter baffle plate (5mm thick) to prevent over-insertion. An insulating handle ensures user safety, while tight tolerances guarantee accurate testing—critical for checking if TNV circuit terminals are inaccessible to unauthorized contact.

Specifications:
• Rod Diameter: 12mm (±0.05mm tolerance; matches TNV circuit gap testing requirements)
• Rod Length: 80mm (±0.2mm tolerance; ensures reach to deep TNV terminals)
• Hemispherical Tip Radius:  6.0mm (±0.05mm tolerance; mimics real-world contact scenarios)
• Baffle Plate Dimensions Diameter: 50mm (±0.2mm); Thickness: 5mm (prevents over-insertion)
• Material Composition – Rod: Conductive metal (for reliable circuit contact); – Handle/Baffle: Non-conductive material (insulating, flame-retardant)
• Key Tolerances Linear dimensions: ±0.2mm; Diameter/radius: ±0.05mm (aligns with standard precision demands)

Test Procedures:
• Inspect the rod for bent conductive parts, cracked insulation, or baffle damage; confirm specs are met.
• Power off the equipment under test (e.g., IT server, AV receiver) and place it on a stable surface.
• Identify TNV circuit terminals and potential access points (e.g., equipment vents, connector gaps).
• Hold the insulating handle, align the hemispherical tip with the access point, and insert until the baffle touches the equipment.
• Check if the rod contacts TNV circuit terminals (via electrical continuity or visual inspection).
• Record results to verify compliance with applicable safety standards.

Applications:
• TNV circuit protection testing of IT equipment (e.g., laptops, servers) per IEC/EN 60950-1 Figure 2C.
• Safety checks for household audio/video devices (e.g., TVs, soundbars) following UL 6500 Figure B.1.
• Compliance testing for telecom equipment (e.g., routers, modems) to ensure TNV terminals are inaccessible.
• Quality control for AV musical instruments (e.g., electric keyboards) during production.
• Pre-certification testing (e.g., CE, UL) for IT/audio/video gear seeking global market entry.
