At KIG, every sacrificial anode undergoes rigorous **electrochemical performance testing** and **spectral composition analysis** to guarantee product reliability and compliance with international standards.

Using **ASTM G97-97** as the testing basis, KIG evaluates each anode’s **closed-circuit potential**, **current capacity**, and **efficiency** under controlled conditions. In parallel, **direct reading spectrometers** imported from Switzerland and Germany are used to verify the alloy composition, ensuring that impurity levels such as Fe, Ni, and Cu meets the standards.

Through this dual testing system, KIG ensures that every magnesium, zinc, and aluminum anode meets the strictest performance and quality requirements, providing long-term, stable protection for cathodic protection systems worldwide.
