DANSK DSF/IEC TR 60825-3 ED3 PDF

This part of IEC 60825, which is a technical report, gives guidance on the planning and design, set-up and conduct of laser displays and shows that make use of high power lasers emitting output between 380 nm and 780 nm. The laser power needed to produce effective theatrical or artistic displays in large spaces such as theatres, arenas, or architectural sites is great enough to pose a severe accidental exposure hazard, even when personal exposure is very brief. For this reason, subclause 4.1.5 of IEC/TR 60825-14 specifies that only laser products that are Class 1, Class 2 or visible- beam Class 3R should be used for demonstration, display or entertainment purposes in unsupervised areas. Laser products of other classes should only be permitted under carefully controlled conditions and under the control of a trained experienced operator. This document is not intended to include the display or demonstration of scientific, medical or industrial laser products. However, several of the principles in this document may be relevant. This document provides recommendations for safety for those laser displays or demonstrations that are shows, artistic displays, advertising or light sculptures, or museum pieces used to demonstrate optical principles, etc. Laser products available for use in a domestic environment or for use by people who cannot be expected to have received a suitable level of training should be Class 1, Class 2 or visible beam Class 3R. Therefore, the use of such equipment is outside the scope of this document. Image projectors that were assigned a Risk Group according to IEC 62471-5 or laser illuminated luminaires employing lamps meeting the criteria of clause 4.4 of IEC 60825-1:2014, are not within the scope of this document.
