EU standards

REACH regulation: The EU REACH regulation strictly controls highly concerned substances (SVHC) in jewelry and accessories. Currently, the list includes over 200 chemical substances, such as polycyclic aromatic hydrocarbons and phthalates. Testing institutions need to use gas chromatography-mass spectrometry (GC-MS) to accurately detect these substances in jewelry and accessories. If the SVHC content in the product exceeds the prescribed limit, they must fulfill their reporting obligations.

EN 1811:2011+A1:2015: This standard specifies the detection method for nickel release in metal jewelry that comes into long-term contact with the skin. Using a solution that simulates human sweat, the amount of nickel released from jewelry during a specific period of time is detected by an atomic absorption spectrometer to prevent consumers from being harmed due to nickel allergies.

American Standard

CPSIA regulation: The Consumer Product Safety Improvement Act (CPSIA) in the United States imposes strict restrictions on harmful substances such as lead and phthalates in children's jewelry. Use atomic absorption spectroscopy to detect lead content in children's jewelry, ensuring compliance with CPSIA standards and safeguarding children's health and safety.

ASTM F2923-17: This standard specifies the method for determining lead in jewelry, metals, and metal alloys, providing a technical basis for detecting lead content in jewelry.
