Abstract / scope
ISO 8062-3:2007 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.
ISO 8062-3:2007 applies to both general dimensional and general geometrical tolerances, unless otherwise specified.
The dimensional tolerances covered by ISO 8062-3:2007 are tolerances for linear dimensions.
The geometrical tolerances covered by ISO 8062-3:2007 are:
- tolerances for straightness,
- flatness,
- roundness,
- parallelism,
- perpendicularity,
- symmetry, and
- coaxiality.
ISO 8062-3:2007 can be used for the selection of tolerance values for individual indications.
