The 'DIN' tells me it's a German standard, because that's the acronym for their equivalent of ANSI. Guidelines for general tolerances indicated on existing drawings are given in Clause 5.
Technical delivery conditions for stampings are specified in DIN 6930-1. This standard is to be applied in conjunction with DIN 6932 on design rules for stamped steel parts. If, as an exception, this standard is also applied to parts made from semi-finished products other than flat products, or from materials other than steel, this shall be agreed separately. General tolerances for parts made by fine blanking (see VDI 2906 Part 5) are not covered by this standard. General tolerances as specified in this standard are used for cold or hot stampings made from flat steel products, and apply wherever reference is made to this standard in drawings or other relevant documents (e.g. By selecting a specific tolerance class, the customary workshop accuracy is taken into consideration. It specifies general tolerances on linear and angular dimensions, and on coaxiality and symmetry with four tolerance classes as follows: f (fine), m (medium), g (coarse) and sg (very coarse). This standard is intended to simplify drawings. 'Abd Allah, Sayf al-Din 5020 Ulucam, Abdusselam 6933 Ulucay, Cagatay.
