Jewelry Test

 

Ornaments are divided into children ornaments and adult ornaments according to the age of users. Different countries have different age definitions for children's jewelry. For example, according to ASTM f2923-14, children's jewelry refers to the jewelry for children aged 12 or under. According to GB 28480-12 regulations on harmful elements of jewelry, children's jewelry refers to jewelry for children aged 14 and under.
 
The testing requirements for children's jewelry are generally stricter than those for adults. The testing items involved can be divided into mechanical and physical performance testing and harmful chemical substance testing.
