3. Inspections and site tests

Upon arrival at the installation site and during installation, the structures and equipment shall be inspected and tested.

The Contractor shall timely reveal and eliminate the defects, if any, prior to commencement of installation and/or tests.

The site tests are subdivided into two stages:

• tests during installation and after completion of installation;

• acceptance tests.

The tests during installation and after completion of installation are performed as per the requirements of factory's instructions, to confirm that the equipment has been properly installed.

The acceptance tests are performed to check the correctness and safety of the equipment's operation and, in particular, to check and confirm the quality of the works implementation. The acceptance tests are performed as per the requirements of factory's instructions, SOU-45.21.3-00100227-22:2010 and SOU-N EE 20.302:2007.

After all structures and equipment are installed and assembled at the site, they shall be tested and trial-operated for the site's conditions.

The tests to be performed by the Contractor at the commissioning stage, are specified by the Technical Requirements.

If any of the test results specified in the Technical Requirements does not satisfy these requirements, the Employer has the right to reject this equipment and demand from the Contractor to replace this equipment with re-testing.

Upon request of the Employer, the Contractor shall perform additional tests specified in the Technical Requirements or in the Contract. In addition, the Employer may request to perform additional tests or repeat the tests already performed, based on the results of the analysis of already performed tests of materials or in case of deviations from standard technology of installation or testing of equipment at the site.
