IEC 60601-2-22:2019

Overview

IEC 60601-2-22:2019 is the fourth-edition particular standard for medical electrical laser equipment, defining requirements for the basic safety and essential performance of surgical, cosmetic, therapeutic and diagnostic laser devices. It applies to laser equipment used on humans or animals and specifically covers devices classified as Class 3B, Class 4, and Class 1C where the enclosed laser is Class 3B or 4. This edition updates the previous (2007) edition to reflect changes in IEC 60601‑1 and IEC 60825‑1:2014, addresses safety issues that have emerged since the prior edition, and clarifies scope (LED medical products are excluded and normally fall under IEC 60601‑2‑57).

Key topics and requirements

The standard supplements IEC 60601‑1 and focuses on laser-specific hazards and system behavior. Major technical topics include:

• Scope and classification of laser products (Class 1C, 3B, 4) and applicability to ME Equipment and ME Systems
• Basic safety and essential performance criteria for laser output delivery to patients/animals
• Identification, marking and documentation requirements for safe use, servicing and labeling
• Protection against radiation hazards (unwanted/excessive optical radiation and safeguards)
• Electrical, mechanical and thermal protection to avoid ancillary hazards during operation
• Accuracy of controls and instruments and protection against hazardous outputs
• Hazardous situations, fault conditions and risk management requirements aligned with the general standard
• Programmable Electrical Medical Systems (PEMS) considerations and electromagnetic compatibility (EMC) expectations
• Testing and verification approaches consistent with IEC 60601 test structure

(These topics reflect the standard’s clause structure and annexes that provide symbols, guidance and rationale.)

Practical applications and who uses it

IEC 60601-2-22 is essential for:

• Medical device manufacturers designing or integrating surgical, cosmetic, therapeutic or diagnostic lasers
• Design verification and safety engineers performing risk assessment and validation testing
• Regulatory and compliance teams preparing technical files for CE marking, conformity assessment, or national approvals
• Test laboratories and notified bodies evaluating laser medical equipment to IEC 60601 series requirements
• Clinical engineers and procurement specialists ensuring safe selection and maintenance of laser systems, including veterinary applications

Use the standard to guide product design, labeling, integration into ME systems, pre‑market testing and conformity documentation.
