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.
