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.

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
