Jewelry and Accessories Testing and Certification Standards

Domestic standards

Harmful substance detection: GB 28480-2012 "Regulations on the Limits of Harmful Elements in Jewelry" strictly limits the migration of harmful elements such as lead, mercury, cadmium, and hexavalent chromium in jewelry. Testing institutions need to use inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption spectroscopy (AAS) to accurately detect jewelry, ensuring that the migration of harmful elements meets standard requirements and avoiding consumers from ingesting harmful elements due to contact with jewelry during use.

Physical performance testing: For jewelry with chains such as necklaces and bracelets, according to relevant standards, a tensile testing machine is used to test the tensile strength of the chain to ensure that it will not break during normal use. For accessories such as watch straps and eyeglass frames, their wear resistance is tested by a wear tester to evaluate the durability of the product.

international standard

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 methods for determining lead in jewelry, metals, and metal alloys, providing a technical basis for detecting lead content in jewelry.
