Fashion Jewelry Products Testing

◉    Service Background

With the development of economy and society, people have begun to pursue fashion and individuality in addition to satisfying basic life needs, which has promoted the development of fashion jewelry, and people have higher and higher quality requirements for fashion accessories.

Because fashion jewelry will be in contact with the skin for a long time, their safety is also highly concerned by consumers. In recent years, incidents such as skin allergies caused by wearing unqualified accessories have occurred from time to time. Countries such as Europe and the United States have been recalled jewelry because they do not meet the corresponding regulations, which directly bring huge economic losses to enterprises. Therefore, companies should pay close attention to control product quality.

For jewelry products, China and European and American countries have formulated corresponding product standards, and made a series of requirements from product performance, raw material selection, test items and testing methods, etc., in order to better achieve product quality control. At the same time, reducing the risk of random inspections of products in domestic and foreign markets is of instructive significance to manufacturers.
