IEC 60601-2-57:2023

Overview

IEC 60601-2-57:2023 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies particular requirements for the basic safety and essential performance of non-laser light source equipment. This equipment is intended for therapeutic, diagnostic, monitoring, cosmetic, and aesthetic applications. The standard applies to medical electrical equipment incorporating optical radiation sources with wavelengths ranging from 200 nm to 3,000 nm, explicitly excluding laser radiation.

This second edition of IEC 60601-2-57 represents a significant update from the 2011 edition, including recent technological advancements in light source equipment. Its primary objective is to ensure reasonable levels of safety, reliability, and performance during the operation of these medical devices, helping manufacturers and healthcare providers maintain industry compliance and patient safety.

Key Topics

• Scope and Application: Covers equipment emitting optical radiation (non-laser) intended to produce photobiological effects on humans for therapeutic, diagnostic, monitoring, cosmetic, and aesthetic use.
• Risk Group Classification: Introduces and clarifies risk groups including the new Risk Group 1C (RG-1C), which adds technical measures to inhibit emission if the applicator is not in proper contact with target tissue.
• Safety Requirements: Details requirements for electrical safety, mechanical protection, prevention of hazardous radiation exposure, and mitigation of excessive temperatures.
• Hazard Controls: Covers protection against electrical and mechanical hazards, unwanted or excessive radiation, hazardous outputs, and fault conditions.
• Testing and Compliance: Specifies general testing procedures to verify equipment safety and performance.
• Marking and Documentation: Mandates clear equipment identification, labelling, and instructions, including specific hazard and warning symbols related to optical radiation exposure.
• Electromagnetic Compatibility: Addresses compatibility to prevent interference affecting device function.
• Exclusions: Excludes lasers and light source equipment intended for veterinary use.
• Normative References: Draws from related IEC standards and provides guidance consistent with IEC 60601-1 series general safety requirements.

Applications

IEC 60601-2-57:2023 applies broadly across a variety of medical devices using non-laser optical radiation for health-related purposes:

• Therapeutic Equipment: Devices that provide light-based treatments such as phototherapy for skin conditions or wound healing.
• Diagnostic Instruments: Tools using optical radiation for patient monitoring and diagnostic imaging.
• Cosmetic and Aesthetic Devices: Equipment delivering light therapy for skin rejuvenation, hair removal, or other aesthetic procedures.
• Monitoring Systems: Optical sensors and devices for continuous patient condition monitoring without laser emissions.

This standard enables manufacturers to design medical electrical equipment that is safe and effective when used in hospitals, clinics, and aesthetic practices worldwide. Compliance also supports regulatory approval and market access in many countries.
