What is BS EN 61920 - Classification of IR devices about? 
Infrared (IR) is invisible electromagnetic radiation. BS EN 61920 describes the classification of IR devices into groups and classes to identify and clarify problems caused by mutual interference. Mutual interference is caused by the increasing parallel application of different IR systems.
BS EN 61920 considers the wavelength range from 700 nm to 1600 nm and includes all systems based on free air applications which intentionally or unintentionally use IR radiation in this range. Products that unintentionally emit IR radiation, such as illumination equipment are not deemed to be IR application systems. They are, however, integrated into BS EN 61920 to enable facility planners to take into consideration and foresee provisions against disturbance of IR application systems by such unintentionally emitted radiation.
Who is BS EN 61920 - Classification of IR devices for? 
BS EN BS EN 61920 on the classification of IR devices is useful for: 
- Manufacturers and suppliers of electronic equipment and components
- Manufacturers and suppliers of IR devices
- Product development teams

Why should you use BS EN 61920 - Classification of IR devices?
Electronic equipment is used in applications that rely on mechanical or electric systems for their operation. They are essential to any work on electronics systems for creating signals and capturing responses from electronic devices. Infrared has applications in industrial, scientific, military, commercial, and medical fields. There are certain standardized specifications contributing to the performance of an IR device.
BS EN 61920 discusses terms, definitions and symbols that depict a user-friendly idea of IR devices. BS EN 61920 provides users with physical characteristics of radiators and receivers which contributes to the performance characteristics of these devices ensuring their reliability. BS EN 61920 also provides a method for minimizing mutual interferences that allows the users to simultaneously use different IR products. The guidelines in BS EN 61920 help you perceive the classification of IR devices that enables you to provide a superior quality product to your customers.
