Introduction
1. Standard background and technological evolution
GB/T32791-2016 Eddy current test method for electrical conductivity of copper and copper alloys is an important standard formulated by China for the electrical conductivity test of copper and its alloy materials. This standard is based on the principle of eddy current method, which uses an alternating magnetic field to induce eddy currents on the surface and near the surface of the conductive material, and then measures the conductive properties of the material. Eddy current method is a non-destructive detection technology with the characteristics of high efficiency and rapidity, and is widely used in the non-ferrous metal processing industry.
2. Comparison of standard frameworks
| Standard dimensions | GB/T32791-2016 | Comparison with international standards |
|---|---|---|
| Method principle | Eddy current method, alternating magnetic field induced eddy current | Consistent with the International Electrotechnical Commission (IEC) standard |
| Test range | 4% IACS ~ 103% IACS | Covering the international common conductivity range |
| Instrument requirements | Measurement accuracy±1% IACS, frequency50kHz~1000kHz | Comply with international testing equipment standards |
3. Implementation suggestions and case analysis
Instrument calibration steps:
- Use high-value and low-value standard test blocks for calibration
- Calibrate every 2 hours of continuous work
- Ensure the probe is parallel and close to the test surface
