DIN IEC/TS 62998-3:2024-12

This part of IEC TS 62998, which is a Technical Specification, specifies general requirements for the development, integration, and maintenance of safety-related sensors (SRS) and safety-related sensor systems (SRSS) that are applicable to all sensor technologies, with particular consideration given to systematic suitability. It is suitable for risk reduction in accordance with all safety-related performance classes of a specified application. It contains guidance on the analysis of sensor technologies of different wavelength ranges, measurement methods, and the sensing unit arrangement in an SRS, respectively the arrangement of SRSs in an SRSS; representative physical properties of safety-related objects with due consideration of their material characteristics and the sensor technology/technologies used in an SRS/SRSS to achieve the detection capability and comparable results during verification and validation; analysis of the interference of objects present in the surrounding on the safety related objects and thereby the influence on the dependability of the detection capability; - use of algorithms during design, development and maintenance to achieve appropriate detection capability and dependability of detection; - appropriate use of algorithms during the integration of SRS or SRSS by the integrator to improve execution of measurement information or provide decision information derived from measurement information. Applications of driverless transport vehicles, service robots used in public areas, or human-machine interaction in the industrial sector show an increasing need for and use of new sensor technologies and new types of sensor functions in relation to the exposure of persons to hazards. In these applications, a rapidly increasing number of sensors with different sensor technologies are used to achieve a high degree of automation, up to and including autonomy. The systematic suitability of such sensors is important for reducing the risk of injury.
