3. Specification by tolerance zone

• Principle

  As mentioned above, during the design phase, the design office defining a product must imagine, for each component of the mechanism, the dimensional and geometric defects compatible with the various technical functions to which they contribute. The definition drawing must therefore include indications reflecting the functional conditions.

• Indication on a drawing (NF E 04-552) (ISO 1101)

A geometric specification is indicated on a drawing using a table linked to the specified entity by an arrow (figure 6 ).
