Proficiency test in the area of flowing media: Pitot tube
A proficiency test is carried out for the the measured variable flow velocity according to the methodology of DIN EN ISO/IEC 17043:2010.
A Prandtl Pitot Static Tube with differential pressure gauge is sent as the calibration item. The calibration procedure can be freely selected. The deviation of the flow velocity at the following measuring points, if they can be visualised, must be determined:
- 2 m/s
- 5 m/s
- 10 m/s
- 15 m/s
- 20 m/s
- 30 m/s
- 50 m/s
- 65 m/s
The assigned reference values are determined using the weighted average of all participant results from the accredited calibration laboratories. The results are evaluated using the En‑value for the assigned value.
Schedule and procedure:
Registration phase: by 22 November 2024
Planned start proficiency test: December 2024
The proficiency test takes place in a ring, whereby a calibration is carried out in the pilot laboratory at least before and after the calibrations of the participants. Each participating laboratory has two calendar weeks to carry out the calibration and is responsible for the insured forwarding of the calibration items. An exact schedule will be sent to the participating laboratories before the start.

A summary of the proficiency tests can be found in the description.
Note: A minimum number of eight participating laboratories must be reached in order to carry out this proficiency test.
