Seminar - IEC 60825-1

International IEC 60825-1 Laser Product Safety Standard Seminar 

IEC 60825-1 is the international safety standard for laser products. In 2014, the new Edition 3 became valid and since then accepted in Europe as EN 60825-1, with acceptance in the USA expected soon. This seminar can be considered as master class for laser product classification and will provide in-depth understanding and background information on the measurement requirements for classification of laser products, as well as the limits for the various laser classes.

Particular emphasis will be placed on Class 1 and Class 2 emission limits, as well as on complex cases of pulsed emission and extended sources, where IEC 60825-1 Edition 3 features significant changes. The seminar thus will have "low power, safe laser products" as main topic; enclosed high power lasers such as materials processing lasers will not be covered.

Seminar topics will include:

• Overview of bio-effects on eye and skin
• Principles of classification
• Relationship of emission limits and exposure limits
• General changes: Class 1C, laser driven light sources
• Extended analysis for extended sources
• Analysis of pulsed and scanned emission

Instructors:

The seminar is held by Karl Schulmeister, PhD, who is a consultant on laser and broadband radiation safety at the Seibersdorf Labor GmbH in Austria, where also a specialised accredited test house is operated. Dr. Schulmeister was the project leader at IEC for the development of Edition 3 of IEC 60825-1 and has been a key member of the IEC and CENELEC laser committee for 20 years.

He is co-author of the handbook "Laser Safety" and author of more than 100 papers on laser and optical radiation safety. The research in his group over the last eight years concentrated on thermally induced injury that also provided the scientific background for amending the spot size dependence and multiple pulse rules of the retinal thermal limits.
