Safety laser scanner certified to IEC TS 62998 for use outdoors
In a world first, TV Rheinland has certified a safety laser scanner for outdoor use as per IEC TS 62998. This globally recognised standard applies to safety-related sensors on machinery designed to protect people. The safety laser scanner "outdoorScan3" from SICK protects people from injury. If the sensor detects the presence of a person in the hazard zone of a machine, it responds by stopping the machine. The safety laser scanner, which is certified for outdoor use, is deployed in stationary applications, automated passenger airbridges and driverless transport vehicles operated on factory premises.
Until now it used to be the case that safety laser scanners could only be certified for indoor use - e.g. for machinery operated inside production halls. Peter Robben, an expert in Functional Safety at TV Rheinland says: "When safety laser scanners are used outdoors, the sensors also have to function reliably even in adverse weather conditions such as fog, rain or snow." Until now, there was no easy way for manufacturers to demonstrate this.
Michael Badeja, product manager at SICK says: "Over the course of several years of collaboration with the International Electrotechnical Commission, our customers, suppliers and testing companies - including TV Rheinland - we have established a test basis for certifying these scanners for outdoor use too," The result of this work and the basis for certification of "outdoorScan3" is the new globally recognised standard IEC TS 62998.
Until now, many options for automated vehicles operated outdoors were implemented in a non-safe manner. Robben says: "This new standard represents a real improvement when it comes to protecting people in hazard zones." Manufacturers can now have their products certified accordingly, thereby demonstrating that their safety laser scanners also function reliably outdoors in accordance with the current state of the art - and protect lives in the process.
