ASTM Publishes Latest Standards for Jewelry

SafeGuardSSoftlinesApril 14, 2020

ASTM International has published the latest version of standards for adult and children’s jewelry. The children’s jewelry standard contains two important technical changes.

In recent months, ASTM International has published its latest version of standards for adult and children’s jewelry. These are:

  • ASTM F2923-20 ‘Standard Specification for Consumer Product Safety for Children’s Jewelry’
  • ASTM F2999-19 ‘Standard Consumer Safety Specification for Adult Jewelry’ 

These two standards contain editorial changes, including the deletion of references to alternative methods, citing the latest version of European, American and CPSC standards. The technical requirements in ASTM F2999-19 for adult jewelry remain largely similar to the 2014 version. 

Additionally, ASTM F2923-20 for children’s jewelry contains two important technical changes:

  • Strengthening the threshold limit for screening cadmium content 4-fold in determining whether accessible metal and plastic components are required to be tested for migratable cadmium
  • Obligation for accessible plasticized materials to conform to the eight phthalates (BBP, DBP, DCHP, DEHP, DHEXP (DnHP), DIBP, DINP and DPENP) falling under 16 CFR 1307 ‘Prohibition of Children’s Toys and Child Care Articles Containing Specified Phthalates’

Highlights of these two important changes in ASTM F2923-20 are summarized in Table 1.

ASTM F2923-20 ‘Standard Specification for Consumer Product Safety for Children’s Jewelry’
EntrySection/TitleHighlight of Changes
19 ‘Specification for Cadmium in Certain Substrate Materials of Children’s Jewelry’

Strengthens the cadmium content limit from 300 ppm to 75 ppm for screening accessible metal or plastic/polymeric components: 

  • Components with no more than 75 ppm cadmium content are not required to be tested for migratable cadmium
  • Small part components (16 CFR 1501.4) with more than 75 ppm cadmium content are required to be tested for soluble cadmium using an acid extraction test
  • Components that are not small parts (16 CFR 1501.4) are to be tested using a saline extraction test
211 “Specification for Phthalates in Plasticized Components of Children’s Jewelry’ 

Completely new section:

  • Accessible plasticized materials are obliged to comply with no more than 0.1% for each of the 8 phthalates falling under 16 CFR 1307 using CPSC-CHC1001-09.4
  • Elastic strings are not considered as accessible

In 2012, Rhode Island became the first US state to regulate children’s jewelry to ASTM F2923-2011 (SafeGuardS 103/12).

Since 2018, Oman has regulated children’s jewelry to ASTM F2923 and adult jewelry to ASTM F2999.
