Determination of Nickel Release

    Nickel Release Test in Imitation Jewelry: Detailed Analysis for Skin Health and Safety

    Imitation jewelry appeals to a wide user base due to its affordable prices and aesthetic appeal. However, the materials used in products that come into direct contact with the skin can pose serious risks to human health. Nickel, in particular, is frequently used in accessory production and has the potential to cause allergic reactions and skin conditions. Under the scope of KKDİK regulations, TAREKS analysis laboratory carries out imitation jewelry testing and nickel release tests with a professional approach.


    Why Is the Nickel Release Test Important?

    The nickel release test measures the amount of nickel that jewelry and accessories release upon contact with the skin, determining whether they meet human health standards. Excessive nickel release can lead to allergic contact dermatitis, especially in sensitive skin. Both the KKDİK regulation and the EU Nickel Directive impose restrictions on the maximum permissible nickel release levels in products.


    Test Process and Scope of Analysis

    TAREKS analysis laboratory conducts nickel release tests using high-precision instruments, following international standards. Our test process includes:

    1. Sample Preparation

      • Jewelry or accessory samples are prepared for testing according to the surface areas that come into contact with the skin.
    2. Simulated Skin Contact

      • The product is placed in an artificial perspiration solution for a specified period, simulating real-life use conditions.
    3. Measurement of Nickel Release

      • The amount of nickel in the solution is determined using sensitive devices (e.g., ICP-MS). The measured value is then compared with the limits set by KKDİK and the EU Nickel Directive.

    Which Products Can Be Tested?

    • Watch Straps: Nickel release is evaluated in watches containing metal parts.
    • Jewelry: All imitation jewelry including earrings, necklaces, rings, and bracelets.
    • Clasps and Other Accessories: Any type of metal-based accessory that comes into contact with the skin.

    Test Standards and Legal Compliance

    TAREKS analysis laboratory provides testing services in compliance with the following standards and regulations:
