IEC TS 60825-13:2026

IEC TS 60825-13:2026 provides manufacturers, test houses, safety personnel, and others with practical guidance on methods to perform radiometric measurements or analyses to establish the emission level of laser energy or power in accordance with IEC 60825-1:2014. The measurement procedures described in this document are guidance for classification of laser products in accordance with IEC 60825‑1:2014. It is possible that other procedures are better or more appropriate.
Information is provided for calculating accessible emission limits (AELs) and maximum permissible exposures (MPEs), since some parameters used in calculating the limits are dependent upon other measured quantities.
This document applies to lasers, including extended sources and laser arrays. The procedures described in this document for extended source viewing conditions can yield more conservative results than when using more rigorous methods.
NOTE Work continues on more complex source evaluations and will be provided as international agreement on the methods is reached.
This first edition cancels and replaces the second edition of IEC TR 60825-13 published in 2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC TR 60825-13:2011:
a) minor changes and additions have been made in the definitions;
b) classification flow has been updated;
c) apparent source sections have been clarified;
d) scanning has been updated;
e) more examples and useful conversions have been added to the annexes.
