IEC 60529 Test Sphere Φ12.5mm with Dynamometer 50N

IEC 60529 Test Sphere Φ12.5mm with Dynamometer 50N is a critical tool for verifying enclosure protection (IP Code) and preventing electric shock in household and similar electrical appliances. Fully compliant with  IEC 60529 Clause 5.2 Figure 5 and Clause 4.3 DIN 40050, it features a precision-machined metal sphere (12.5mm diameter) to simulate small-object access, an insulating handle guard for user safety, and an integrated dynamometer for accurate 10N-50N thrust measurement. The built-in baffle plate prevents over-insertion, ensuring consistent testing. Its durable stainless steel sphere and robust insulation withstand repeated use, making it ideal for manufacturers, labs, and certifiers validating appliance safety.

Specifications:
• Test Sphere Diameter:  12.5mm (±0.1mm tolerance; aligns with IP20/IP21 small-object test requirements)
• Baffle Plate Dimensions Diameter: 4mm (±0.1mm); Thickness: 10mm (±0.2mm) – prevents excessive insertion into enclosures
• Handle Specifications Diameter: 4mm (±0.1mm); Material: Flame-retardant insulating plastic (UL94 V-0 rating)
• Dynamometer Range:  10N, 20N, 30N, 40N, 50N
• Test Sphere Material:  304 stainless steel (corrosion-resistant, maintains spherical shape; no burrs)
• Compatibility:  Works with household, commercial, and low-voltage industrial electrical appliances

Test Procedures:
• Inspect the sphere for dents, the handle for cracks, and the dynamometer for calibration (ensure accuracy within ±3N).
• Power off the appliance under test and secure it on a flat, stable surface.
•  Set the dynamometer to the required thrust level (e.g., 30N for IP20 compliance checks).
•  Hold the insulating handle, align the 12.5mm sphere with potential access points (e.g., vents, control gaps).
•  Apply steady thrust until the dynamometer reaches the set force; check if the sphere touches live/hazardous parts.
•  Record results (pass/fail) to confirm adherence to IP Code and safety standards.

Applications:
•  IP20/IP21 protection testing of household appliances (e.g., refrigerators, washing machines) per IEC 60529.
•  Electric shock prevention checks for small kitchen appliances (e.g., blenders, coffee makers).
•  Quality control for consumer electronics (e.g., desktop computers, audio speakers) to block small-object access to live parts.
•  Enclosure compliance testing for low-voltage industrial control panels (non-hazardous areas) per DIN 40050-9.
•  Pre-certification testing (e.g., CE, GS) for electrical devices entering EU/UK markets, validating IP Code requirements.
