Increasing parallel application of different IR systems can cause mutual interferences. To identify and make transparent these problems, a classification of IR devices into groups and classes is proposed. Goal of standardization is to avoid or at least to minimize mutual interferences and to enable coexistence of different IR products. It is provided to mark each IR product with its characteristic parameters according to the classification criteria. It is not object of this prestandard to describe the consequences of interferences between IR systems as well as radiation safety aspects of optical radiation. Due to the physical character of optical emission the possibility of local limitation is a special feature of IR radiation. In this prestandard the wavelength range from 700 mm to 1600 mm wil be considered. Included are all systems based on free air application, which send intentionally or unintentionally IR radiation in this range. Excluded is each kind of fiber optics. In this context "free air" means freely radiated IR in indoor or outdoor applications. If the IR systems are used for information transmission, this prestandard is only to be seen in connection with the Physical Layer of the ISO-OSI Reference Model (EN 498).
