Micro-grooves are often marketed as "safer" because the edges provide grip. EN 17168 mandates a dry slip resistance (CSR) of ≥ 0.30 (low slip potential) and, for wet areas (kitchens/bathrooms), a wet slip resistance of ≥ 0.40 (R9 equivalent). It does not cover vertical barriers, systems using

It does not cover vertical barriers, systems using bars or ropes, or specific normative fire performance requirements for barriers acting as firewalls. Key Technical Requirements While general conservation standards exist (such as those

Released in 2019, this standard addresses a critical gap in heritage science. While general conservation standards exist (such as those for metals or textiles), arms and armour are unique hybrid objects that combine complex materials (metals, leather, wood, textile, bone) with mechanical functionality and historical significance. EN 17168 moves beyond simple "repair" and establishes a modern, preventive conservation approach tailored specifically to these objects.
