IEC 61032 Figure 6 Test Probe 2 – 12.5mm Stainless Steel Sphere

The IEC 61032 Figure 6 Test Probe 2 is a precision 12.5mm stainless steel sphere engineered to verify that electrical equipment enclosures prevent ingress of solid objects, specifically assessing protection against access to hazardous live parts or moving components. Fabricated from corrosion-resistant stainless steel, this test probe maintains dimensional accuracy within ±0.1mm tolerance for repeatable compliance verification. Its ergonomic design facilitates manual application during testing procedures, simulating accidental contact scenarios where small objects might penetrate enclosure openings. This tool is essential for validating compliance with international safety standards including IEC 60335, IEC 60065, IEC 60745, IEC 61029, and IEC 60950 for both consumer and industrial electrical products.

Specifications:
• Probe Type: IEC 61032 Test Probe 2 (12.5mm steel sphere for solid object protection verification)
• Steel Sphere Diameter: 12.5 mm ± 0.1 mm (precision-machined to standard specifications)
• Material: Stainless steel (corrosion-resistant, durable construction for repeated testing cycles)
• Surface Finish: Polished smooth (prevents damage to equipment enclosures during testing)
• Core Function: Validates enclosure protection against 12.5mm solid objects (IP2X protection level) to prevent hazardous access
• Applied Force: Minimal force application (simulates accidental contact with small foreign objects)

Test Procedures:
• Inspect the steel sphere for surface imperfections (e.g., dents, corrosion) that could affect dimensional accuracy.
• Identify potential ingress points on the equipment enclosure (e.g., ventilation openings, access gaps).
• Apply the sphere gently to each opening from multiple approach angles.
• Determine whether the sphere penetrates the enclosure or contacts hazardous components.
• Document test results against safety standard requirements (pass/fail determination).

Applications:
• IP2X protection verification for household appliances (e.g., refrigerators, washing machines) per IEC 61032 Figure 6 requirements.
• Safety compliance testing of electronic equipment housings (e.g., power supplies, networking devices) for 12.5mm object exclusion.
