🔬 EN 1811 Compliance

Nickel Release Calculator

Estimate nickel release from body jewelry alloys and check compliance against the EU EN 1811 piercing limit of 0.2 µg/cm²/week (REACH Annex XVII, Entry 27).

Returns nickel content, estimated release rate, and EN 1811 compliance status. Covers 15 materials including implant-grade alloys, gold, silver, and polymers.

Estimate release rate from known nickel content. Uses an empirical model calibrated against EN 1811 literature data. Not a substitute for a certified test report.

Regulatory disclaimer: Estimated release rates are derived from an empirical model based on EN 1811 literature and are for guidance only. Actual nickel release depends on alloy processing, passivation quality, surface area, skin pH, sweat chemistry, and wear conditions. To demonstrate EN 1811 compliance for product sale in the EU, obtain a certified test report from an accredited laboratory. The EU nickel limit for piercing jewelry is 0.2 µg/cm²/week (REACH Annex XVII, Entry 27; EU Directive 94/27/EC, as amended by 2004/96/EC).
