#ISO 8062 3 ISO#
International ISO standard does not use these terms, but specifies the tightest geometrical tolerance grade as one to be used only by "special agreement". Per the NADCA specifications, high pressure die casting tolerances are divided into two groups: normal and precision tolerances. ISO 8062-3:2007 Geometrical product specifications (GPS) Dimensional and geometrical tolerances for molded parts Part 3: General dimensional and geometrical tolerances and machining allowances for castings.ISO/TS 8062-2 Geometrical product specifications (GPS) Dimensional and geometrical tolerances for molded parts.ISO 8062-1:2007 Geometrical product specifications (GPS) Dimensional and geometrical tolerances for molded parts.ISO 8062-1…3 consists of the following titles. The former ISO 8062 defined tolerances only as CT (Casting Tolerance) grades. ISO 8062-1…3 defines casting tolerances as DCT (Dimensional Casting Tolerance) grades and GCT (Geometrical Casting Tolerance) grades. ISO 8062:1994 did not have specifications to high pressure die castings. This series replaces the former ISO 8062:1994.
There is also the international ISO standard series, which focuses on casting tolerances. The North American Die Casting Association (NADCA) has standard specifications for setting high pressure die casting tolerances.
