IEC 60745-2-5 Figure 105 Test Probe A

The IEC 60745-2-5 Figure 105 Test Probe A (12mm diameter, 50mm length) is engineered for verifying accessibility to hazardous components in handheld motor-operated tools, specifically rotary tools such as drills, impact drivers, and angle grinders. This precision instrument features a rigid 12mm-diameter stainless steel probe with a 50mm working length to simulate small object or finger contact, coupled with an insulated polyamide handle for operator protection during testing. Manufactured to exact dimensional tolerances, it applies controlled force to assess whether dangerous moving parts are accessible during normal operation. Essential for tool manufacturers and testing laboratories, it ensures compliance with international safety standards including IEC 60745-2-5, reducing injury risks from rotating gears and blade housings.

Specifications:
Tool Type: Test Probe A (IEC 60745-2-5 Figure 105; for hazardous part accessibility testing in handheld rotary tools)
Probe Material: 304 stainless steel (high rigidity; maintains structural integrity under test force; corrosion-resistant for industrial environments)
Handle Material: Polyamide (PA) – insulated (electrical resistance ≥ 100MΩ); heat-resistant up to 120°C; non-slip grip for operation in oily or wet conditions
Key Dimensions:
|- Probe Diameter: 12mm ± 0.1mm (critical parameter for simulating small object access)
– Working Length (Probe Tip to Handle): 50mm ± 0.2mm
– Total Length (Probe + Handle): Typical 150mm ± 0.5mm (ergonomic design for tool testing applications)
– Tip Shape: Flat (prevents artificial damage to tool casings during testing)
Applied Force: 10N ± 0.5N (simulates accidental contact force; aligns with IEC 60745-2-5 safety criteria)
Core Function: Tests accessibility of hazardous parts in rotary tools (gears, blades); validates effectiveness of protective casings; ensures compliance with international tool safety standards including IEC 60745-2-5

Test Procedures:
1. Inspect the probe for bent sections, cracked handles, or diameter deviations; confirm 12mm ± 0.1mm with a caliper.
