Tolerances apply to:
is a German industrial standard (Deutsches Institut für Normung) that defines the dimensions, tolerances, and inspection principles for involute splines with a module series based on a reference diameter . Unlike the more common DIN 5480 (which is based on a reference diameter and module), DIN 5482 is an older standard typically used for light-duty to medium-duty applications where manufacturing simplicity and interchangeability are required without the complexity of heavy-duty serrations.
For new designs, use DIN 5480 (metric module) or ISO 4156 . For repair/maintenance of existing equipment, DIN 5482 data remains essential. din 5482 spline standard pdf

, which are grooves cut into shafts and hubs that mesh together to transmit high torque loads efficiently. This standard is widely used in automotive and industrial machinery for applications requiring precise alignment and durability.

The missing PDF causes the most pain here. DIN 5482 uses specific tolerance classes for the hub (H) and shaft (f). These are not interchangeable with ISO tolerances. Without the official tables, you cannot gauge the "major diameter fit" or "root diameter clearance."
eBay.de (Germany) or abebooks.com occasionally sell vintage "DIN Taschenbuch" (DIN Pocketbooks). Look for (Passfeder, Keile, Splines) from the 1980s. This contains the original DIN 5482. For repair/maintenance of existing equipment, DIN 5482 data
Because the standard is old, your modern CNC hob may not have the exact DIN 5482 profile stored. You will likely need to order a custom hob from a specialist like Gleason or Samputensili, providing them a scanned copy of the from the PDF.
