ISO 6930-2:2004 specifies the requirements for weldable high yield strength steels for cold forming. It applies to plates and wide-flats, hot-rolled on reversing mills, both having a thickness between 4 mm and 50 mm (inclusive) and supplied in the normalized, normalized rolled and as-rolled delivery condition.

Ac) With regard to the continuous technical progress, the illustrations and descriptions contained in the catalogue and the price lists and on our homepage shall be non-binding and shall therefore not constitute any expectations of the buyer with respect to any specific properties of the goods which may lead to the assumption of a material defect in accordance with section 434, clause 1, sentence 3 BGB. B) The customer's compliance with his obligation of inspection, notification and rejection in accordance with section 377 of the German commercial code (HGB) shall form the prerequisite for our liability for defects.

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). By selecting a specific tolerance class, the customary workshop accuracy is taken into consideration. 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. Delivery conditions). General tolerances for parts made by fine blanking (see VDI 2906 Part 5) are not covered by this standard. 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. This standard is to be applied in conjunction with DIN 6932 on design rules for stamped steel parts. Technical delivery conditions for stampings are specified in DIN 6930-1. Guidelines for general tolerances indicated on existing drawings are given in Clause 5.
