The geometrical tolerances covered by this part of ISO 8062 are: - tolerances for straightness, - flatness, - roundness, - parallelism, - perpendicularity, - symmetry, and coaxiality. The dimensional tolerances covered by this part of ISO 8062 are tolerances for linear dimensions. 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. DIN EN ISO 8062-3, 2008 Edition, September 2008 - 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) This part of ISO 8062 specifies general dimensional and geometrical tolerances, as. It is applicable for the tolerancing of dimensions and geometry of castings in all cast metals and their alloys produced by various casting manufacturing processes. 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.
