This has been addressed before. TYP stands for "Typical", and is no longer in use on drawings created under ASME Y14.5-1994, having been replaced with an accounting of the actual number of occurances using "X" (i.e. 4X).
I don't know how DIN or other standards define its use.
TYP is the abbreviation for TYPICAL. It means that the notation applies to all like features. For instance, if all holes in a part view are the same only one hole needs detailed dimensions and the annotation TYP means all holes are the same. Saves having to dimension all holes that are the same in a view.
"TYP." usually means that the dimension is typical of other locations on the drawing. This will reduce the clutter of redundant dimensions on the drawing but may add to confusion if not used properly.
