- Steps to evaluate maximum permissible exposures (MPEs) and accessible emission limits (AELs)
- Procedures for dealing with extended sources and laser arrays
-
Foundation for Laser Product Classification
The technical specification serves as a reference for classifying lasers based on measured emissions and calculated exposure limits, as defined in IEC 60825-1:2014.
-
Uncertainty Management
Instrument requirements and methods for evaluating measurement uncertainties are described, with an emphasis on calibration traceability and comprehensive consideration of error sources.
-
Product Testing Considerations
Guidance is given on:
- Configuring laser products and accessories for testing
- Assessing reasonably foreseeable single fault conditions
- Accounting for collateral radiation and all possible accessible configurations
-
Updated Content
The 2026 edition introduces updated terminology, improved classification flow, clarifications on apparent sources, revised scanning sections, and expanded practical examples.
