DGUV Test: EFFICIENTLY POSITIONED

• 1. Lifesaving assistant for safe reversing

  Reversing, including maneuvering for short distances in commercial vehicles, is often dangerous due to the size of the vehicle and the drivers visibility. Accidents with material damage or serious personal injuries occur time and again. Technical facilities for improving visibility and for automated monitoring of the rear route are intended to support drivers when reversing, protect people and pedestrians in the danger area and avoid accidents caused by collisions.

  Due to the great importance of reversing assistants for the safety and health of people, the Testing and Certification Body for Traffic and Environment of the DGUV Test has developed test principles in cooperation with the Testing and Certification Body of the Institute for Occupational Safety and Health. The principles summarize the current state of the art and place requirements on the functional performance and reliability of reversing assistance systems. Products that meet these requirements offer greater security.

• 2. Making technology secure and preventing attacks

  In order for components of protective devices on machines and systems (e.g. light grids, laser scanners, safety programs on electronic controls) to function safely and reliably, their safety-relevant data and functions must be protected from unauthorized access. This topic is at the center of the "Security" test principles of DGUV Test.

  Attacks on standardized hardware and software components can trigger threats. The effects of attacks are diverse and in the simplest case lead to the machine or production plant being switched off and thus to financial damage to the person operating it. They pose dangers for the employees: It is conceivable that attacks on components of functional safety are carried out and that safety parameters are specifically changed or overridden.

  For safety and health at work, it is crucial to have preventive influence on the security of machines and components through testing and certification. For this reason, DGUV Test has developed test principles that enable the testing and certification of the security of components of industrial automation systems. A certificate awarded by DGUV Test entitles the holder to affix a DGUV Test mark “Security tested” with the suffix “industrial security tested”.

• 3. Safety on the construction site

  Over 80 accidents were registered with quick-change devices on excavators in the last 10 years, most of them serious, nine fatal - a considerable burden for the families, work teams and insurers concerned. An investigation showed that attachments (e.g. loading and digging tools) were often not secured correctly due to time constraints - the attachments came loose and fell onto construction workers. The applicable safety requirements are therefore not to be assessed as sufficient from the point of view of safety and health.

  DGUV Test therefore set new test requirements for quick-change devices in 2020. In order to receive a certificate from the DGUV Test Testing and Certification Body BAU, in addition at least one of the safety requirements listed in the GS-BAU-25 test principles must be fulfilled. For example, the excavator can be retrofitted in such a way that it is technically only possible to lift an attachment if it has been locked correctly. Or there must be an acoustic warning signal if the locking has not been fully implemented. With such additional securing, comparable accidents are very likely to happen less frequently.
