Calibration Services of ISM3D S.L.

ISM3D S.L. is a measurement and calibration laboratory, accredi-ited by ENAC, the Spanish accre-ditation body, which is signatory of the European Mutual Recognition Agreement.

ISM3D has a wide scope of accredited measurement ser-vices, most with a very lowmeasurement uncertainty. Allcalibrations are performed withhigh accuracy coordinate mea-suring machines (CMMs), twoof them tacile CMMs and one optical (video CMM).

The traceability goes to National Standards principally via ball beams.

There are three groups of accre-dited services:1. calibration of artefacts2. verification of CMMs3. calibration of master parts.

The calibration of artefacts com-prises tactile and optical artefacts.ISM3D's speciality are optical ar-tefacts and very large artefacts:- step gages and gage blocks- ball beams 1D- optical target scales 1D- ball plates 2D- optical raster plates 2D- ball artefacts 3D (3D ball beams, tetrahedrons, cubes)

Best uncertainties for 1D artefact calibrations are:0.2 µm + 0.5 µm *L/m

Largest tactile 1D artefacts are 5 m

Largest optical 1D artefacts are 1 m
