A three-level proficiency testing scheme is proposed in the form of the interlaboratory comparisons for the determination of the tank capacity of all possible types calculated by the laboratories’ own software. The proficiency testing scheme will be available to any accredited or non-accredited laboratory worldwide. Each laboratory chooses from the proposed computational tasks what it needs. To protect the confidentiality of the information within the framework of this scheme, all the Participants generate their individual codes, which they indicate in the file name with the results of their calculations.
The laboratories are suggested to pass successfully three levels of operation characteristics testing ranked by the increase of the set tasks:
1) calculation of the tanks’ interval capacities without introducing any corrections by their 3D models prepared by the Provider;
2) calculation of the tanks' interval capacities by introducing all necessary corrections by their 3D models prepared by the Provider;
3) calculation of the tanks’ interval capacities by scans that have not been subjected to preliminary preparation by the Provider.
To participate in the first level of the proficiency testing, it is necessary to:
— download the program of proficiency testing of the first level from the site SE «Ukrmetrteststandart» https://metrology.kiev.ua/ru/mezhlaboratornye-sravneniya;
— download files with point coordinates on the tank wall from Google disk Comparison: http://bit.ly/vgsucsm;
— calculate interval capacities of the tanks without the introduction of any corrections;
— send files with calibration tables of the tanks to the Provider’s e-mail: firstname.lastname@example.org;
— if the submitted data is suitable for analysis, then register and pay for the service;
— receive the results of the proficiency testing via your e-mail;
— read the publication of the proficiency testing results in the journal «Measurement infrastructure» https://mi-journal-online.org.
At the first level of the proficiency testing, the payment is fulfilled only for the registration of the Participant and the execution of the documents on the completion of this level.
