Children's Jewelry Standard

Several states have enacted laws over the years with the intent of increasing the safety of children's jewelry. Examples are the laws which have been passed to restrict cadmium content. Some of the laws which were passed, however, were not based on scientific research and the requirements and methods vary from state to state. Approved in 2011, the "Standard Specification for Consumer Product Safety for Children's Jewelry" is a comprehensive specification which serves to establish a group of harmonized, nationally recognized test methodologies and requirements for children's jewelry. Although this standard is considered to be voluntary in most states at this time, Rhode Island has adopted it into law for all children's jewelry which is manufactured after December 18, 2012 and other states are likely to follow suit in the near future.

As a jewelry manufacturer you most likely utilize materials beyond metal in your products. Those components must also comply with the regulations. Due to the inherent differences in the make-up of component materials, TTL Laboratories employs the proper advanced testing methodologies including cryogenic milling and high-pressure microwave digestion or hydrofluoric acid digestion for:
