ActiveZinc and aluminum based coatings on steel sheets and strips—Determination of lead and cadmium contents—Inductively coupled plasma mass spectrometric method
钢板及钢带 锌基和铝基镀层中铅和镉含量的测定 电感耦合等离子体质谱法
Application Summary AI generated
This standard specifies an inductively coupled plasma mass spectrometry (ICP-MS) method for determining lead and cadmium content in zinc-based and aluminum-based coatings on steel sheets and strips. It is applied in the metallurgical industry for quality control and environmental compliance testing of coated steel products, such as galvanized or aluminized sheets used in automotive, construction, and appliance manufacturing. The method ensures accurate detection of trace heavy metals to meet regulatory limits on hazardous substances in materials.
