BS ISO 15786:2008 Technical drawing. Simplified representation and dimensioning of holes

BS ISO 15786 has been established to specify the simplified representation and dimensioning of holes. It establishes rules to determine, unambiguously, methods for the representation — both complete and simplified — and the dimensioning of holes, as well as the structure and sequence of the descriptive elements for the simplified representation of holes.

Contents of BS ISO 15786:

  • Foreword
  • Introduction
  • Scope
  • Normative references
  • Terms and definitions
  • Methods of representation and dimensioning of holes
  • Complete representation and complete dimensioning of holes
  • Complete representation and simplified dimensioning of holes
  • Simplified representation and simplified dimensioning of holes
  • Representation of holes on the same drawing
  • Structure of dimensioning of holes
  • Structure and sequence of descriptive elements for simplified dimensioning of holes
  • Graphical symbols
  • Number of groups of holes and number of holes in a group
  • Indication of tolerances
  • Hole bottom
  • Countersinks and chamfers
  • Depth dimensions
  • Indication of surface texture
  • Indication of dimensions on geometrical tolerances
  • Examples for representation and dimensioning of holes, counterbores and internal threads
  • Bibliography
