scope:

NEN-EN 16704-2-2 deals with requirements for barriers to give users the possibility to prevent workers from entering the danger zone unintentionally by the use of such barriers. This standard defines minimum requirements and test procedures for these barriers concerning the dimensions, the stability and electrical properties. This standard also gives recommendations for the marking (visual demarcation line) where a person would enter the danger zone. For combinations of barriers and TWS see also EN 16704-2-1:2016. This standard contains references to electrical hazards from third rail systems.
