ISO/TC 213/WG 9 - Dimensional and geometrical tolerancing for castings

ISO 8062-4:2017 specifies general geometrical tolerances using surface profile tolerances related to a general datum system that remains on the final part. It also specifies machining allowances and draft angles (tapers) for castings in all cast metals and their alloys produced by various casting manufacturing processes. NOTE When there is no datum system (target or integral) on surfaces remaining in the final condition, this document cannot be applied.

ISO/TS 8062-2:2013 gives the rules for geometrical dimensioning and tolerancing of final moulded parts and parts machined out of moulded parts. It also gives rules and conventions for the indications of these requirements in technical product documentation and specifies the proportions and dimensions of the graphical symbols to be used. ISO/TS 8062-2:2013 provides symbols which may be used to identify the relative completeness of the moulded features and parts. These graphical symbols should not be confused with the graphical symbols for surface texture according to ISO 1302, which are notably larger.

ISO 10135:2007 specifies rules and conventions for the indications of requirements for moulded parts on technical product documentation. It also specifies the proportions and dimensions of the graphical symbols used for this representation.

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.
