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

This 12.5mm Test Sphere with 50N Dynamometer 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 and 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.

Standards:

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 (±3N accuracy per force level; real-time thrust readout)
Test Sphere Material:  304 stainless steel (corrosion-resistant, maintains spherical shape; no burrs)
Overall Length Approximately:  100mm (ergonomic design for comfortable, controlled testing)
Compatibility:  Works with household, commercial, and low-voltage industrial electrical appliances

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

Applications:
1. IP20/IP21 protection testing of household appliances (e.g., refrigerators, washing machines) per IEC 60529:2021.
2. Electric shock prevention checks for small kitchen appliances (e.g., blenders, coffee makers) following UL 60335-1:2024.
3. Quality control for consumer electronics (e.g., desktop computers, audio speakers) to block small-object access to live parts.
4. Enclosure compliance testing for low-voltage industrial control panels (non-hazardous areas) per DIN 40050-9:2020.
5. Pre-certification testing (e.g., CE, GS) for electrical devices entering EU/UK markets, validating IP Code requirements.
