IEC 62368 Annex T.5 250N Enclosure Force Test Apparatus

The IEC 62368 Annex T.5 250N Steady Force Compliance Testing Apparatus is engineered to assess the structural integrity of external enclosures in audio/video (AV), information, and communication technology (ICT) equipment—including laptops, smart televisions, and networking devices. This precision instrument delivers a calibrated steady force of 250N±10N through a 30mm-diameter circular contact surface, applied for approximately 5 seconds to the top, bottom, and lateral surfaces of equipment enclosures. Constructed with a rigid stainless steel contact plate for uniform force distribution and an insulated handle for operator control, it verifies that enclosures maintain structural integrity without deformation or exposure of hazardous components under specified pressure conditions. Essential for manufacturers and testing laboratories, this apparatus validates compliance with IEC 62368-1 safety requirements.

Specifications:
Tool Type: 250N Steady Force Testing Apparatus (IEC 62368-1:2024 Compliance; for enclosure integrity evaluation of AV/ICT equipment)
Contact Surface: Stainless steel circular plate – Diameter: 30mm ±0.5mm (ensures uniform force distribution); Surface Finish: Smooth (prevents enclosure damage)
Applied Force: Steady force: 250N ±10N (calibrated to IEC 62368-1 Annex T.5 requirements)
Force Application Time: ~5 seconds per test point (aligned with global safety testing protocols)
Handle Material: Insulated engineering plastic (PA66) – Heat-resistant up to 120°C; Non-slip grip; Electrical resistance ≥100MΩ
Excluded Test Components: Handles, levers, knobs, CRT display faces, or transparent covers (unless removal exposes ES3 components or axial force is typical in operational use)
Core Function: Evaluates AV/ICT enclosure resistance to 250N force; Prevents deformation-induced hazardous part exposure; Ensures IEC/CSA/UL compliance

Test Procedures:
1. Inspect the apparatus: Verify contact plate diameter (30mm±0.5mm) and force calibration (250N±10N) with a calibrated gauge.
