NEN 6068 geeft een gedetailleerde methode voor de bepaling van de weerstand tegen branddoorslag en brandoverslag tussen ruimten in gebouwen

Deze norm heeft betrekking op betonconstructies die geheel of gedeeltelijk zijn vervaardigd met vooraf vervaardigde betonproducten die voldoen aan NEN-EN 13369 en de eventuele specifieke productnorm en die worden belast door belastingen.
Dit deel van deze normenreeks geeft aanvullende regels voor het ontwerp en berekenen van betonconstructies met vooraf vervaardigde betonproducten en betonnen bouwdelen. De regels moeten worden toegepast samen met de geldende normen voor betonconstructies en vooraf vervaardigde betonproducten.

Deze norm geeft aanvullende regels voor de vervaardiging, het ontwerp en het berekenen van systeemvloeren met vooraf vervaardigde kanaalplaten, eventueel voorzien van een ter plaatse gestorte druklaag. De regels zijn aanvullingen op de geldende normen voor betonconstructies en NEN-EN 1168. 

Deze normen geeft aanvullende regels voor de vervaardiging, het ontwerp en het berekenen van met vooraf vervaardigde voorgespannen of gewapende breedplaten vervaardigde systeemvloeren, oftewel breedplaatvloeren. De regels zijn aanvullingen op de geldende normen voor betonconstructies en NEN-EN 13747. 

Deze NPR geeft een toelichting bij de methode voor de bepaling van de weerstand tegen branddoorslag en brandoverslag tussen ruimten in gebouwen, zoals omschreven in NEN 6068:2020/Ontw. A1:2023. In deze NPR ligt de nadruk op de branduitbreiding via de gevel.
