Anotace

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
