Overview

EN IEC 60601-2-57:2026/A11:2026 is an amendment to the European adoption of IEC 60601-2-57, addressing basic safety and essential performance of non‑laser light source equipment used for therapeutic, diagnostic, monitoring, cosmetic and aesthetic purposes. The amendment adds the normative Annex ZA (mapping to corresponding European publications) and informative Annex ZZ (relationship to Regulation (EU) 2017/745, the Medical Device Regulation). These Annexes are required to harmonize the standard with EU regulatory requirements and to support a presumption of conformity when the standard is cited in the Official Journal of the EU.

Keywords: EN IEC 60601-2-57, non-laser light source equipment, medical electrical equipment, Regulation (EU) 2017/745, photobiological safety.

Key Topics

  • Scope and intended use: Safety and essential performance requirements for non‑laser optical radiation medical devices (LEDs, IPL, phototherapy and similar sources) for clinical, cosmetic and monitoring applications.
  • Optical emission and photobiological safety: References photobiological safety guidance (e.g., IEC 62471) and addresses risks associated with emitted optical radiation.
  • Risk management and conformity: Aligns device risk reduction and manufacturer policies with the General Safety and Performance Requirements (GSPR) of MDR 2017/745.
  • Labeling, instructions and warnings: Requirements for device labels, safety symbols, instructions for safe use, installation, maintenance and pre‑use checks to minimize exposure risks.
  • Electrical and mechanical risks: Coverage includes electrical safety aspects related to cooling fluids and access to operational controls.
  • Regulatory mapping: Annex ZA provides normative cross‑references to international standards adopted as European documents; Annex ZZ shows clause‑by‑clause correspondence to MDR Annex I GSPR to support conformity assessment.

Applications and Who Uses This Standard

  • Manufacturers and designers of medical, cosmetic and aesthetic light‑based devices (LED therapy, IPL, phototherapy units).
  • Regulatory and compliance teams preparing technical documentation and demonstrating conformity with MDR (EU) 2017/745.
  • Quality, risk management and clinical evaluation specialists integrating safety, post‑market surveillance and clinical requirements.
  • Notified bodies and test laboratories evaluating device safety, optical emission testing and labeling.
  • Hospitals, clinics and biomedical engineers referencing safe operation, maintenance and user instructions.

Practical use: implement design controls, perform photobiological risk assessments, prepare instructions for use and labeling aligned with MDR GSPR, and ensure harmonized national adoption following Annex ZA/ZZ guidance.

Related Standards

  • EN IEC 60601-1 (general medical electrical equipment safety)
  • IEC 62471 / EN 62471 (Photobiological safety of lamps and lamp systems)
  • IEC 60947-3 / EN IEC 60947-3 (low-voltage switchgear – referenced for electrical components)
  • ISO 3864-2 (graphical symbols and safety labels)

Using EN IEC 60601-2-57 and its Annexes ZA/ZZ helps manufacturers and assessors demonstrate compliance with EU medical device requirements for non‑laser light source equipment, improving product safety and market access.
