IEC 62368 Annex T.4 100N Steady Force Test Tool

The 100N Steady Force Test Tool for IEC 62368 Compliance is engineered for assessing the mechanical integrity of external enclosures in audio/video (AV) and information-communication technology (ICT) equipment—such as tablets, desktop speakers, and modems. It applies a precise steady force of 100N±10N across a 30mm-diameter circular stainless steel surface, exerted for approximately 5 seconds on the top, bottom, and sides of enclosures. Featuring an insulated ergonomic handle for operator control, it ensures enclosures withstand real-world pressure without deforming or revealing hazardous components (e.g., live circuits). Essential for manufacturers, it verifies adherence to international safety standards to maintain device safety during operation. Specifications:

• Tool Type: 100N Steady Force Test Tool (IEC 62368-1:2024 Annex T.4 Compliance; for mechanical strength testing of AV/ICT equipment enclosures)
• Contact Surface: Stainless steel circular plate – Diameter: 30mm ±0.5mm (ensures uniform force distribution); Surface Finish: Smooth (no burrs to prevent enclosure scratches)
• Applied Force: Steady force: 100N ±10N (calibrated to IEC 62368-1 Annex T.4 requirements)
• Force Application Time: Approximately 5 seconds per test point (aligned with international safety testing protocols)
• Handle Material: Insulated engineering plastic (PA66) – Heat-resistant up to 120°C; Non-slip grip for stable operation; Electrical resistance ≥100MΩ
• Excluded Test Components: Handles, levers, knobs, CRT faces, or transparent/translucent covers (unless removal exposes ES3 parts)
• Core Function: Tests AV/ICT enclosure resistance to 100N force; Prevents deformation-induced hazardous part exposure; Ensures compliance with IEC/CSA/UL standards

Test Procedures:

1. Inspect the tool: Verify contact plate diameter (30mm±0.5mm) and force calibration (100N±10N) using a calibrated gauge.
2. Place the AV/ICT equipment under test (EUT, e.g., a tablet) on a flat, non-conductive stable surface.
3. Identify test points: Focus on EUT external enclosures…
