DAkkS Calibration

Inspection room

The laboratory of FRENCO GmbH was accredited by Deutsche Akkreditierungsstelle (DAkkS) according to DIN / ISO 17025 as conformity assessment centre for all essential gear features (Accreditation certificate DK-15199-01-00). This means, helix and involute artefacts as well as pitch artefacts and gears with pitch, radial runout and dimension over measuring circle can be DAkkS-calibrated.

Artefact with workpiece

As a result, you receive a multiple-faceted DAkkS calibration certificate with explanations regarding the measuring method, information on the location, determination of the measured item and specification of the measurement uncertainties.

Measuring uncertainties

The measuring uncertainty of DAkkS-calibrations lies within the following range (U for k=2):

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
Dimension over measuring circlesMdK: 1,2 μm

The smallest measurement uncertainty to be indicated depends on the size of the artefact. Details of the accreditation range can be viewed on http://as.dakks.eu/ast/d/D-K-15199-01-00.pdf.

Artefact 100

The actual accreditation certificate according to DIN EN ISO/IEC 17025:2005 can be downloaded here.

Artefacts which are outside this accreditation range can be executed as factory calibration.

Documentation

As a result, you will also receive a multiple-faceted calibration certificate with explanations regarding the measuring method, on the location, determination of the measured item and of course with specification of the measurement uncertainties – which you can also download as PDF.
