DIN 6930-2:2011-10

This standard is intended to simplify drawings. It specifies general tolerances on linear and angular dimensions and on coaxiality and symmetry in four accuracy grades which are meant for use and hot stampings made from steel flat products. They shall apply whenever reference is made to this standard on drawings or relevant documents (e. g. in delivery conditions). General tolerances for parts made by fine blanking are not covered in this standard. If, by way of exception, it is intended to apply this standard also to components made from semi-finished products other than flat products, or from materials other than steel, this shall be particularly agreed. This standard shall be applied in conjunction with the specifications given in DIN 6932. DIN 6930-1 is valid for the technical delivery conditions of stamped parts. Regulations for general tolerance in existing drawings are included in clause 5.
