Standards Development
This part of IEC 60825 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 in accordance with IEC 60825-1:2014 (herein referred to as “the standard”). The measurement
procedures described in this technical report are intended as guidance for classification of laser products in
accordance with that standard. Other procedures are acceptable if they 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 is intended to apply to lasers, including extended sources and laser arrays. Users of this document should be aware that the procedures described herein for extended source viewing conditions may yield more conservative results than when using more rigorous methods.
This technical specification is intended to provide manufacturers, test houses and users with practical guidance on methods to perform radiometric measurements or analyses to determine the classification of laser products in accordance with IEC standard 60825-1. The standard is quite complex requiring proper application of optical radiation physics. After much discussion with the IEC official at the meeting of TC76, it was decided to go to DTS as TRs are now being discouraged/phased out.
You are now following this standard. Weekly digest emails will be sent to update you on the following activities:
