Chinese Jewelry Testing - GB 28480

Jewelry adds beauty to life with its delicacy. In this era of self - expression, a wide variety of jewelry items keep emerging. Jewelry has close contact with the skin, enhancing one's charm. However, if jewelry contains toxic and harmful substances or other potential hazards, it will pose a hidden danger or even a threat to your health and safety. According to the jewelry - related regulations or standards in many countries and regions around the world, there are many control factors, mainly including various toxic chemical substances and mechanical and physical safety. Although these regulations or standards have the same control purpose, the specific controlled objects, requirements, and limit values vary from place to place.

Our country also has strict requirements for jewelry. GB 28480 - 2012 "Regulations on the Limits of Hazardous Elements in Jewelry" is China's first mandatory standard restricting harmful substances in non - precious metal jewelry (excluding gemstones and jade), which has been officially implemented since May 1, 2013. The standard stipulates that all kinds of non - precious metal jewelry and ornaments (excluding gemstones and jade) need to meet the corresponding standard requirements. The limits of harmful substances in precious metal jewelry are regulated by another mandatory standard, GB 11887 - 2012 "Regulations on the Purity of Precious Metals in Jewelry and Nomenclature Methods". These two standards limit the content of multiple heavy metals in all metal - based jewelry, and the controlled items and limit requirements are the same.
