<p>A broad spectrum of activities based on physical dimension is covered by the laboratory force, pressure and weighting instruments.</p> <p><b>Force</b></p> <p>The force is the result of the action of acceleration on a mass. The force is generated in the laboratory using calibrated masses in the range 2.5 N up to 100 kN. A weight bridge with force generation using a hydraulic piston is used from 100 kN up to 2 MN. We are able to generate force in compression as well as traction.</p> <p><b>Weighing instruments</b></p> <p>A weighing instrument measures a force (the weight) and the calibration or approbation of this type of instrument requires similar equipment than force calibration.</p> <p><b>Pressure</b></p> <p>The pressure is defined as a force per unit area. In practice, the pressure is generated using rotating piston manometers in the range 10 kPa up to 1 GPa. A system with fixed piston and force generation is used from 10 Pa up to 10 kPa. Pressure in the range 10-5 Pa to 10 Pa is defined by static expansion of gas.</p> <p>The laboratory performs calibration, in all the range, in absolute pressure, and above 1 Pa in gauge pressure.</p> </div> </div> </div> <div class="tab-pane clearfix " id="tab0__content_metas_en_home_fabe_druck_jcr_content_par_tabctrl"> <h2 class="sr-only visible-print-block">Services</h2> <div class="mod mod-textimage"> <div class="clearfix"> <figure style="max-width:inherit"><img src="/metas/en/home/fabe/druck/_jcr_content/par/tabctrl/items/tab0/tabpar/textimage/image.imagespooler.jpg/1703155883787/588.1000/druck-dl.png" alt=""/></figure> <p>The calibration laboratory is working according to the norm ISO 17025 and the calibration certificates are recognized worldwide.</p> <p><b>Calibration</b></p> <p><i>Force</i><br> We perform routinely the calibration of force sensors according to ISO 376 from 2.5 N up to 100 kN.

The laboratory can determine the effective area of piston cylinder units used in pressure balance.</p> <p><i>Weighing instruments</i><br> We perform the verification of weighing instruments according to the 芦 calibration guide 18 禄 published by Euramet.</p> <p><b>Approval and conformity assessment</b></p> <p>We perform the measurements required for the technical assessment of load cell (OIML R60) weighting instruments (OIML R76) or dynamic weighting instruments.

above 100 MPa</li> <li>Improvement of the procedures and of the measurement uncertainty above 200 kN </li> <li>Traceability of the force under 1 mN.</li> </ul> </div> </div> <div class="multilist "
