scope:
This part of ISO 8062 specifies general dimensional and geometrical tolerances, as well as machining allowance grades, for castings as delivered to the purchaser in accordance with ISO 8062-2. It is applicable for the tolerancing of dimensions and geometry, and required machining allowance of castings in all cast metals and their alloys produced by various casting manufacturing processes.
This part of ISO 8062 applies to both general dimensional and general geometrical tolerances (referred to in or near the title block of the drawing), unless otherwise specified, and where specifically referred to on the drawing by one of the references in Clause 9.
The dimensional tolerances covered by this part of ISO 8062 are tolerances for linear dimensions.
The geometrical tolerances covered by this part of ISO 8062 are:
- tolerances for straightness,
- flatness,
- roundness,
- parallelism,
- perpendicularity,
- symmetry, and
- coaxiality.
This part of ISO 8062 can be used for the selection of tolerance values for individual indications.
NOTE This part of ISO 8062 does not apply to 3D CAD models used without indicated dimensions.
