DIN stands For Deutsches Institut für Normung (German Institute for standartisation) and they are a Set of guidelines and regulations for nearly everything. So If you for example buy a Din certificated screw from one manufacturer it will have at least the same propperties as one with the same DIN certificat from another manufacturer.
Having such a system of certification makes live much more easy and safer for everyone involved.
