Updated Competence Database

The Competence database is based on the member's competence profiles in geometric and dimensional metrology. Each profile consists of several services which have been defined according to different dimensional metrology items (instruments, standards and artefacts, tools and methods, specific objects as well as supporting tasks).

The current database figures are:

  • 45 active members
  • 476 member records
  • 2776 services defined
  • 3045 available parameters
  • 1277 specified parameters
