IEC TS 60825-20:2025 provides radiation safety requirements (normative) and guidelines (informative) for the consideration of faults for Class 1 laser devices with laser radiation directed towards the eyes or face. Requirements for the safety of the nominal emission are not in the scope of this document.
Examples:
− devices with laser light facial or ocular recognition;
− virtual reality headsets or glasses;
− devices with gesture tracking via eye or facial movements;
− driver surveillance cameras;
− full body scanners (including eyes, face, and body).
Products exempted from this document include:
− medical and ophthalmic devices;
− automotive (lidars), lamps;
− laser applications where the laser is used in a professional (non-consumer) setting and is intended for direct or long-time exposure of the eyes or face.
This document provides normative requirements and informative guidelines for:
− radiation safety analysis;
− production-line testing;
− hazard analysis for laser radiation emissions (using a modified safety-focused FMEA approach)
NOTE all subsequent references to FMEA in this document refers to this safety-focused FMEA approach.
− examples of typical failure modes and mitigation techniques
