ASTM F2923 Children’s jewelry testing

The complete ASTM F2923 specification is very complex and extensive, and only a summary of it is outlined here. The best way to ensure that your product is fully compliant with ASTM F2923 is to hire a professional testing provider. RTS performs jewelry testing according to ASTM F2923 and a number of other specifications applicable in the United States, the European Union and Canada



The exquisite jewelry embellishes the beauty of life. In this era of personality, all kinds of accessories continue to emerge. The close contact between the jewelry and the skin adds luster to you. However, if the jewelry contains toxic and harmful substances or other potential dangers, it will bring hidden dangers to your health and safety, and even threats! According to the current jewelry related laws and regulations or standards in many countries or regions in the world, there are many control factors, mainly including various toxic chemicals and mechanical and physical safety. Although these regulations or standards have the same control purpose, the specific control objects, requirements and limits vary from place to place.

The definition of jewelry in the new ASTM F2923-20 standard for Children’s jewelry is similar to the scope set by the California jewelry Code, that is, products designed and intended to be used as decorative items for personal wear; Includes:

1. Anklets, armbands, bracelets, brooches, chains, crowns, cuff links, hair accessories with decorative elements, earrings or earmuffs, necklaces, brooches, rings, body piercing jewelry, or jewelry placed on the mouth

2. Parts of the jewelry listed in (1) above,

3. Trinkets, beads, chains, rings, pendants or other accessories that can be worn alone or in conjunction with the items listed in (i) above may be removed from shoes or clothing

4. Timepieces belonging to jewelry components, if they are removable, do not include the timepiece itself

5. Jewelry components in a handmade set, which are ultimately assembled into jewelry and designed to be worn by people

In March 2020, the American Society for Materials and Testing (ASTM) published Standard ASTM F2923-20, a consumer safety specification for children’s jewelry prepared by its Consumer Product Commission (F15) Jewelry Subcommittee (F15.24).
