Pressure and Vacuum

Christian Elbert

More than 60 laboratories are currently represented in the Technical Committee “Pressure and Vacuum“. A broad mix of participants, consisting of equipment manufacturers, users in  in-plant laboratories and service providers, guarantees the representation of the different stakeholders. Moreover, the chairperson‘s participation in committees of the Accreditation Body DAkkS and the Federal Ministry of Economics ensures the coordination of interests, which is further intensified through the regular participation of employees from the DAkkS and the PTB in the meetings of the Technical Committee. These meetings, which usually take place on an annual basis, serve as a communication platform to promote the mutual exchange and to facilitate discussions on current topics of metrology. For example, the calibration of small differential pressures at high static pressures as well as the ever-increasing demands regarding the accuracy of the pressure measurement represent the challenges that are placed on the calibration laboratories by the industry. 

In addition to the current tasks, the different internal working groups of the Technical Committee work on fundamental specialized topics in cooperation with the employees of the PTB. For example, the calibration guideline DKD-R 6-1 is currently being revised. The first version had found its way into the international world of calibration years ago and still serves as a basic document. Various translations as well as its use in an EA guideline underline its global significance. The working group for particularly small pressures, i.e. the working group “Vacuum”, can claim a similar success. Here too, a pathbreaking fundamental work was carried out by creating the  Guideline DKD-R 6-2.

Last but not least, the DKD Technical Committee complements its role as technical committee of PTB by organizing and executing interlaboratory comparisons. This range of interlaboratory comparisons serves the accredited laboratories as a proof of suitability and guarantees the customer technical competence within the scope of services.

To round things off, trendsetting topics form an integral part of the agenda and are regularly discussed. In the ”digital” age, special emphasis is given to the possibilities of electronic generation and transfer of calibration data.
