It specifies general tolerances on Iinear and angular sizes and on coaxiality and symmetry in four accuracy grades which are designed for use and hot stampings produced from metal flat products. They shall utilize whenever benchmark is produced to this standard on images or relevant docs (elizabeth. In delivery conditions). General tolerances for parts made by great blanking are not covered in this standard.

If, by way of exception, it is usually intended to apply this standard also to elements produced from semi-finished items some other than level items, or from materials various other than metal, this shall be particularly decided. This regular shall become applied in association with the specifications given in DIN 6932. DIN 6930-1 is valid for the technical delivery problems of stamped components. Rules for common tolerance in present drawings are usually incorporated in clause 5.
