    IEC 60825

    Standard for safety of laser products, including laser-based medical devices.

    Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed May 5, 2026

    Definition

    IEC 60825-1 classifies laser products (Classes 1, 1M, 2, 2M, 3R, 3B, 4) and specifies labeling and protective measures. Medical-laser-specific requirements appear in collateral standards and product-specific particular standards.
    What the regulation says
    IEC 60825 is a foundational standard for laser safety, with regulators globally, including the FDA and EU notified bodies, expecting adherence for MedTech devices incorporating lasers. Compliance demonstrates that laser radiation risks have been addressed in design and manufacturing, aligning with general safety requirements like those in EU MDR Annex I, Chapter II, Section 10.3 regarding radiation hazards. The standard provides a framework for classifying laser products and implementing appropriate control measures to protect users and patients from hazardous optical radiation.

    What this means in practice

    Critical for surgical, ophthalmic, and aesthetic laser devices; also referenced for high-intensity LED products.

    Examples

    • A manufacturer designing an ophthalmic laser for refractive surgery must classify the device according to IEC 60825-1 and apply appropriate protective housing, interlocks, and warning labels.
    • A dental laser system, classified as Class 3B, requires specific administrative controls, operator training, and the use of laser protective eyewear in the treatment room.
    • During a regulatory audit, a notified body reviews a medical aesthetic laser device's technical documentation to verify that its laser classification and safety features adhere to IEC 60825-1.
    Common pitfalls
    • •Misinterpreting "laser product" to exclude MedTech devices that integrate lasers, rather than standalone laser systems.
    • •Failing to consider the entire optical path and potential reflections when classifying a laser system or designing protective measures.
    • •Overlooking the need for ongoing validation of laser safety controls throughout the product lifecycle, not just during initial design.
    • •Assuming compliance with IEC 60825-1 alone is sufficient, without considering collateral or product-specific standards relevant to medical applications.
    • •Inadequate training of users on laser safety protocols and the meaning of warning labels.

    Frequently asked questions

    The primary purpose is to classify laser products based on their potential hazard level and to specify the required control measures, labeling, and user information to ensure safety.
