ActiveJewellery-Determination of nickel content-Method of flame atomic absorption spectrometry
首饰 镍含量的测定 火焰原子吸收光谱法
Application Summary AI generated
This standard specifies the flame atomic absorption spectrometry method for determining the nickel content in jewellery products. It is applied in the jewellery industry for quality control and compliance testing, particularly to ensure that nickel release from items like earrings, necklaces, and bracelets meets safety limits for preventing allergic reactions. The method is used by manufacturers, testing laboratories, and regulatory bodies to verify nickel content in metallic jewellery components.
