IEC 62368-1 Figure 20 Test Hook

Specifications:
• Probe Type: IEC 62368-1 Figure 20 Test Hook (for AV/ICT equipment hooking risk testing)
• Hook Material: Stainless steel (rigid, corrosion-resistant, maintains hook shape accuracy)
• Handle Material: Nylon (insulating, heat-resistant, non-slip for secure grip)
• Key Dimensions:
– Hook Tip Diameter: 1.0 mm ± 0.05 mm
– Hook Opening Width: 5.0 mm ± 0.1 mm
– Effective Hook Length: 60 mm ± 0.2 mm
– Handle Length: 120 mm ± 0.5 mm
– Total Length: 180 mm ± 0.5 mm
• Applied Force: No appreciable force (mimics light, accidental hooking contact with equipment).
• Core Function: Verifies inaccessibility of hazardous live/mechanical parts via hookable gaps in AV/ICT equipment.

Test Procedures:
• Inspect the test hook for damage (e.g., bent tip, cracked handle) to ensure accuracy.
• Power on the AV/ICT equipment and let it reach normal operating mode.
• Hold the nylon handle and align the hook tip with potential hookable gaps (e.g., wire exits, vent slits).
• Gently insert and maneuver the hook toward internal hazardous parts (e.g., live wires, small gears).
• Check if the hook catches or touches any dangerous components.
• Record whether the equipment meets safety requirements (pass/fail).

Applications:
• Safety testing of AV equipment (e.g., soundbars, projectors) to prevent hookable internal wire access (IEC 62368-1 Figure 20).
• Compliance checks for ICT devices (e.g., network routers, server enclosures).
• Verification of portable AV/ICT gear (e.g., laptop docking stations, Bluetooth speakers) for hooking hazards.
• Quality control for commercial AV systems (e.g., conference room audio mixers) during manufacturing.
• Post-production audits of home ICT equipment (e.g., smart home hubs) to meet global safety standards.
