This part of ISO 8062 can be used for the selection of tolerance values for individual indications. This standard, ISO 8062-4, avoids the insufficiencies of ISO 8062-3 and is in full compliance with the GPS rules. 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. 1 Tapered Thread BSP-BS21,DIN 2999,ISO 7/1 Thread Nominal Actual O. For long-series or mass production for raw castings according to ISO 8062-3:2007. As a general rule of thumb, youll need to place at least 1/3 the height of. 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. Linear Dimensional Casting Tolerance Grades (DCTG). 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.
