LINNY CO Product Safety & Testing
The LINNY CO product line stands up to rigorous U.S. and international testing standards — the same tests trusted for children's jewelry, hypoallergenic metals, and corrosion-resistant materials.
We don't just meet the requirements. We exceed them.
Our flatback studs, huggies, and necklaces have been tested by QIMA Testing Limited and have passed ASTM F2923-20, the Standard Specification for Consumer Product Safety for Children's Jewelry.
This certification confirms that these pieces are nickel-free, corrosion-resistant, and hypoallergenic, exceeding the requirements of both ASTM F2923-20 and ASTM F2923-11.
SAFETY TESTING
CPSIA Section 101 — Lead in Children's Products
Ensures our jewelry contains far below the federal limit for lead.
California Health & Safety Code — Lead & Cadmium
Confirms compliance with California's strict heavy-metal regulations.
California Proposition 65 — Heavy Metal Safety
Meets Prop 65 limits for safe, everyday wear.
ASTM F2923 — Children's Jewelry Chemical Safety
Verifies materials are non-toxic and compliant for children's jewelry.
ASTM F2923 — Mechanical Safety (Edges & Durability)
Ensures no sharp edges and safe performance under real-life use.
16 CFR 1500 — FHSA Mechanical Hazards
Passes federal impact, torque, and tension tests to ensure components remain secure.
HYPOALLERGENIC TESTING
EN 1811 & EN 12472 — Nickel Release Testing
Our earrings release zero detectable nickel, meeting the highest global hypoallergenic standard.
PERFORMANCE TESTING
ASTM B117 — Salt Spray Corrosion Test (Waterproof/Sweatproof)
Simulates exposure to water, sweat, saltwater, and humidity.
We achieved Rating 6: no corrosion, proving our earrings are: Swim-safe, Sweat-safe, Tarnish-resistant, Water-ready.
Hand Wash Durability Test — 10 Cycles
No discoloration or fading after repeated washing. Confirms long-term durability and color stability.
Our additional jewelry collections—such as statement earrings and hair accessories—are designed for adults and currently fall outside the children's jewelry testing program. However, as our brand continues to grow, we remain dedicated to expanding our comprehensive safety and testing program to meet evolving global standards.
