Information on the tolerance list

NOrm ISO 3601-1

DIN ISO 3601-1 is an internationally recognized standard that provides information on permissible dimensional deviations in the manufacture of O-rings.

tolerance zone

The plus/minus tolerance field indicates in mm which tolerance is permissible for the production of O-rings. The size of the field is in relation to the D1 or D2 size.

Shape and surface

In addition to the manufacturing tolerance, ISO 3601 also specifies the permissible form and surface deviations. The deburring area and offset are interesting in practice.
