To obtain an official, legally compliant copy of the complete DIN 6935 standard document including all precise charts, text, and annexes, you can purchase it directly from Authorized Standards Dealers. The primary distributor for German national standards is (the official publishing house of DIN). Alternatively, international clearinghouses like ISO , ANSI , or IHS Markit offer digital PDF downloads of the standard for industrial and commercial use.

Unlike general tolerance standards (like ISO 2768), DIN 6935 specifically addresses two critical aspects of sheet metal bending:

The DIN 6935 standard is crucial in ensuring the quality and reliability of spring washers used in critical applications. Spring washers play a vital role in maintaining the integrity of bolted joints, providing a secure connection and preventing loosening due to vibration, thermal expansion, or other external factors. The standard helps manufacturers produce high-quality spring washers that meet specific performance requirements, reducing the risk of failure and ensuring the safety of people and equipment.

DIN 6935 uses a variable ( v ) (also referred to in literature as the neutral axis shift factor). The standard defines ( v ) based on the ratio ( r/s ) (radius divided by thickness):
