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.
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.
The measuring uncertainty of DAkkS-calibrations lies within the following range (U for k=2):
|Profil||Fα: 1,5 - 2,1 μm||fHα: 1,1 - 1,9 μm||ffα: 0,9 - 1,0 μm|
|Trooth trace||Fβ: 1,5 - 2,0 μm||fHβ: 1,1 - 1,8 μm||ffβ: 0,9 - 1,0 μm|
|Pitch/ Runout||Fp: 0,7 μm||fp: 0,6 μm||Fr: 1,0 μm|
|Dimension over measuring circles||MdK: 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.
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.
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.
