Update on the IEC 60825-13 technical report on laser radiation measurements and the ANSI Z136.4 recommended practice for laser safety measurements for hazard evaluation
Bibliographic record
Abstract
The International Electrotechnical Commission (IEC) 60825-13 Technical Report on Laser Radiation Measurements is being prepared as a new committee draft. The group responsible for developing this Technical Report is Working Group (WG) 3 of the IEC Technical Committee 76. WG 3 membership includes representatives from Australia, Austria, Finland, Germany, Italy, Japan, Romania, Sweden, Switzerland, the United Kingdom, and the United States. IEC 60825-13 is intended to be used as a guide for making radiometric measurements of laser and LED radiation levels for comparison with the AELs and MPEs in IEC 60825-1. The American National Standards Institute (ANSI) Z136.4 Recommended Practice for Laser Safety Measurements for Hazard Evaluation has passed subcommittee and is in committee draft for vote form. Current membership working on the Z136.4 document includes the National Institute of Standards and Technology, the Food and Drug Administration, the Department of Defense, Industry, Professional Societies, the Canadian Department of Defense, and the UK’s National Radiological Protection Board. Z136.4 is intended to provide guidance for measurement procedures used for classification and hazards evaluation of lasers to manufacturers, Laser Safety Officers (LSOs), and trained laser users.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
