IEC 62368 Aluminium Ring – Precision FOD Test Accessory for Wireless Charging

The KingPo IEC 62368 Aluminium Ring is a specialized test object used to verify the safety and Foreign Object Detection (FOD) efficacy of wireless power transmitters. In accordance with the thermal injury protection requirements of IEC 62368-1, this wireless charging foreign object test ring simulates metallic items—like jewelry or small hardware—that may be inadvertently placed on a charging surface. If the transmitter fails to detect this interference, eddy currents can cause the ring to reach hazardous temperatures. Our precision-engineered ring allows laboratories to measure this temperature rise with scientific accuracy.

As a dedicated IEC 62368 test aluminium ring, this component is essential for engineers performing Clause 9.6.2 (Radiated power transfer) compliance checks. By utilizing a specific 99.5% aluminium alloy, our rings provide a standardized reactive load that ensures your test results are globally comparable and meet the stringent audit requirements of international certification bodies.

KingPo Factory Advantages

KingPo maintains an industry-leading laboratory accessory production line, specifically focused on IEC 62368-1 and UL 62368-1 compliance tools. Unlike generic metal rings, our IEC 62368 aluminium ring is CNC-machined to a tolerance of ±0.05mm, ensuring the surface area and mass are perfectly balanced for repeatable testing. We utilize a proprietary thermocouple bonding technique that uses high-temp thermally conductive epoxy, ensuring the K-Type sensor remains in direct contact with the aluminium core even under rapid heating cycles. With a monthly capacity of 10,000 units, we support the world’s largest consumer electronics OEMs and third-party labs with rapid-response lead times and CNAS-traceable material reports.

Professional Construction & Technical Precision

• Standardized Geometry: Fully compliant with the inner/outer diameter and thickness ratios defined in IEC 62368-1 Figure 48.

• Advanced Thermal Sensing: Integrated Class 1 K-Type Thermocouple provides a temperature range from -40°C to +300°C with minimal thermal lag.

• Surface Consistency: The aluminium surface is treated to maintain stable emissivity and conductivity, preventing data drift caused by oxidation.

• FOD Specific Design: Optimized for 110kHz to 205kHz frequency ranges commonly used in Qi-certified and proprietary wireless charging protocols.

Primary Use Cases & Business Value

• Certification Readiness: A mandatory tool for obtaining CE, UL, and CCC marks for any device featuring wireless power transmission.

• R&D Safety Buffering: Helps firmware engineers calibrate the FOD sensitivity thresholds to prevent “nuisance tripping” while maintaining user safety.

• Supply Chain Quality Control: Benchmarking different wireless charging coil suppliers against a standardized IEC 62368 test aluminium ring to ensure consistent safety performance.

Compliance & Regulatory Assurance

This accessory is fully optimized for IEC 62368-1:2018 (Edition 3) and the latest IEC 62368-1:2023 (Edition 4) updates. It also aligns with the U.S. DOE Test Procedures for energy-consuming appliances involving wireless power. For laboratories pursuing ISO/IEC 17025 accreditation, we provide optional certificates of calibration and material purity analysis to ensure total measurement traceability.
