On December 24, 2020 the final meeting of the Interdepartmental Council of the National Quality Infrastructure was held, with the Chairman of State Secretary - Deputy Minister of Economic Development of the Russian Federation - Alexei Khersontsev. The main issues discussed at the meeting were the requalification of accredited persons for conformity with the criteria established by the Government of the Russian Federation for inclusion in the National Part of the EAEU Unified Register, and summing up the implementation of the Russian Government Decree No. 1236 dated September 21, 2019.

As a result of meetings of the Interdepartmental Council, a positive decision was taken to requalify the CB NTP Truboprovod for inclusion in the National Part of the EAEU Unified Register.

Start-Prof version 4.84 R3 release. Changes:

1. Updated code ASME B31.5-2019 Refrigeration Piping and Heat Transfer Components (USA);
2. Updated code ASME B31.12-2019 Hydrogen Piping and Pipelines (USA);
3. Added Pipes, Tees, Bends and Reducers properties according to the EN codes: EN 10216-1:2013, EN 10216-2:2013, EN 10216-3:2013, EN 10216-42013, EN 10216-5:2013, EN 10217-1:2019, EN 10217-2:2019, EN 10217-3:2019, EN 10217-4:2019, EN 10217-5:2019, EN 10217-6:2019, EN 10217-7:2019, EN 10253-1:1999, EN 10253-2:2007, EN 10253-3:2008, EN 10253-4:2008;
4. Added the short description of PASS/START-PROF COM Interface that allows for side applications on C#, Basic and other programming languages to create, modify and analyze models using START-PROF and read the analysis results. It is used for creation of plug-ins for START-PROF software. Full description available upon request. For example, the following plugins was written using the PASS/START-PROF COM-Interface;
5. Export to PCF, Import from PCF, Export to CAESAR II, Import from CAESAR II, Import from PDMS, QA (quality assurance) software, that automatically analyze a lot of models and compare results with previous versions. Any company can create an own plugin for seamless integration of PASS/START-PROF software into company’s workflow. It is possible to write a plugin that will automatically invoke PASS/START-PROF stress analysis from 3D modeling software in background and transfer the analysis results back or generate the reports following the corporate templates. Also it allows creating a plugin for data conversion between PASS/START-PROF and any other software. Furthermore, the plugin for piping model optimization or running complex sequences of parametric model piping stress analysis can be created;
6. Added ability to import the model from Excel Spreadsheet. It can be used to import the model geometry from manually created spreadsheet;
7. Added ability to import the model using data extraction from AutoCAD. It can be used to import the piping geometry from Autocad;
8. Added ability to specify the stiffening rings on the pipe element, that is used for vacuum piping buckling analysis;
9. Added ability to put the miter joints on the ends of the bend elements and other fittings;
10. Added ability to set the turbine, compressor, pump, and nozzle movements manually if they are provided by manufacturer;
11. Added new codes SNiP III-42-80* and SP 86.13330.2014 for construction stage of pipelines;
12. Pipe database is updated with the latest version of ASME B36.19M-2018;
13. EN 13941: Now using the effective axial force instead of true axial force during stress calculation;
14. Removed restriction to specify different pressures and temperatures on the pipes, connected to the fittings (tees, bends, reducers). Now the greatest temperature and greatest pressure are used for fittings wall thickness check, SIF and k-factor calculation (if required by specific code);
15. Built-in calculator is added to the more fields of user interface;
16. Added ability to switch between neighboring pipe objects without closing the dialog;
