DIN 867: "basic rack for involute teeth of cylindrical gears for general engineering and heavy engineering". It describes what is module, pitch and so on. It describes roughly the reference profile. This reference is usually written on a drawing to indicated standard metric tools should be used.
ISO class 5 corresponds roughly to AGMA 12, so very high quality gears. However, those 2 standards are not directly comparable.
Hope this helps any.
