Geometrical product specifications (GPS) — Dimensional and geometrical tolerances for moulded parts — Part 3: General dimensional and geometrical tolerances and machining allowances for castings
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.
