03/07/12 Memorandum of Understanding signed by IMBIH and VSL
Mr. Zijad Džemić from IMBIH (Institute of Metrology of Bosnia and Herzegovina) and Mrs.dr. Nellie Schipper from VSL (Dutch Metyrology Institute) signed a Memorandum of Understanding (MoU). Parties emphasize the importance of collaboration in the field of metrology and recognize that this cooperation between the two metrology institutes will create favorable conditions for trade, industry, health, law enforcement and economic relations.
12/01/11 VSL score of EMRP calls 2011 are very good for Health, SI en New Technologies
On 28th November 2011 the projects which are selected for the EMRP calls 2011 in the fields of Health, SI (the international system of measurement units) and New Technologies were published. EMRP is a European Metrology Research Programme and contains long running projects of collaboration between the different national measurement institutes, aimed at innovative measurement technologies with impact on the European industry and society.Within the three calls 47 project proposals were submitted, the so-called Joint Research Proposals (JRPs). Eventually 29 of these JRPs were selected. VSL was involved in 14 JRPs, of which 9 were successful. Of two of these nine projects VSL is project coordinator. All selected projects are expected to start mid 2012.
04/28/11 VSL CMC certified for a SVP calibration facility in USA
On April 27th Cees van ‘t Wout (manager calibration and reference materials) presented the first “VSL CMC certified” certificate for a Small Volume Prover calibration facility to Tony Tielen (General Manager at Honeywell). The hand-over took place during a meeting held at VSL in The Netherlands. A VSL CMC certified calibration facility may use a special VSL logo on their calibration certificates. This logo ensures customers of the calibration facility that all needed resources are in place to perform good and accurate calibrations. This includes the traceability to international accepted measurement standards, the uncertainty calculation or better known as the Calibration and Measurement Capabilities (CMC) and round robin tests with other calibration facilities around the world.
03/07/11 How to measure dimensional drift
Dimensional drift of sensors, materials and joint structures puts critical limitations to precision engineering and applications with ever increasing demands on measurement uncertainty. Together with TNO Science & Industry and Delft University of Technology, VSL has developed an optical intererometric "Picodrift" measurement platform to explore dimensional drift. The challenges are to distinghuish dimensional changes of a sample from other effects, such as thermal expansion, and to achieve the required picometer level measurement uncertainty. Examples for applications that push the requirements to measurement uncertainty and dimensional stability to the limits are nanolithograpy in semiconductor device manufacture and space science instrumentation.
