DAkkS Calibration

FRENCO offers DAkkS calibration certificates for toothed artefacts.

The laboratory of FRENCO GmbH was accredited by Deutsche Akkreditierungsstelle (DAkkS) according to DIN / ISO 17025 as conformity assessment body for all essential gear features.

  • DAkkS calibration of external involute, tooth trace and pitch artefacts
  • DAkkS calibration of gears and splines for pitch, runout and dimension over pins
  • DAkkS calibration certificate with detailed explanations (measurement uncertainties, measuring method etc.)
  • Factory calibration for artefacts which are outside the accreditation range

Measuement Uncertainties

The smallest measurement uncertainty to be indicated depends on the size of the artefact. The Measurement uncertainty (k=2) of DAkkS calibrations lies within the following range:

ProfilFα: 1.5 - 2.1 μmf: 1.1 - 1.9 μmf: 0.9 - 1.0 μm
Trooth traceFβ: 1.5 - 2.0 μmf: 1.1 - 1.8 μmf: 0.9 - 1.0 μm
Pitch/ RunoutFp: 0.7 μmfp: 0.6 μmFr: 1.0 μm
