Antimony(Sb) | 60ppm |
Arsenic(As) | 25ppm |
Selenium(Se) | 500ppm |
3. nickel release requirement: it should be less than 0.2μg/cm2/week for body-pierced and 0.5μg/cm2/week for long-term skin contacting jewelry.
4. cadmium requirement: the total cadmium or soluble cadmium should be less than the limit shown as below table.
Material | Cd(total)<300ppm | Need migratable test | Cd(soluble) | compliant |
Plastic | Y | N | -- | Y |
N | Y | <75ppm | Y | |
≥75ppm | N | |||
Metal | N | -- | Y | |
N | Y | <200µg | Y | |
≥200µg | N |
5. liquid filled jewelry requirement: should not contain any material listed in 16 CFR 1500.231 or materials which would require special labeling under 16 CFR §1500.14 Permitted liquids in liquid filled children’s jewelry should be screened to eliminate potential hazards in accordance with the current published version of Consumer Safety Specification F963.
