Product Quality Assessment

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.

The aesthetics and usability of jewelry are also highly concerned. Currently, most metal jewelry on the market has a series of quality problems after being worn for a certain period, such as chain breakage, earring backs slipping off, metal rusting, and surface darkening. So, how can we control the quality effectively?
