A further unit shall then be delivered within one week for test. The Applicant/Participant shall provide to the laboratory full information about the installation. handling. After verification (“test recheck”). If any functional component is inoperative. new selection documentation with a new reference and date of publication shall be put in the Eurovent Certified Performance website. the laboratory can destroy the units. and the corresponding invoice shall be sent by Eurovent Certita Certification to the Applicant/Participant. The laboratory shall inform Eurovent Certita Certification and the technical contact of the Applicant/Participant. Only the independent laboratory personnel shall be permitted to handle test units.c. or the unit is damaged and cannot be repaired at the Laboratory. the test is considered as “Passed”. IV. The laboratory will send a short report to Eurovent Certita Certification. IV.3 Software See APPENDIX B. if the software is still not in accordance with the test results OM-10-2016 Published January 2016 Page 6 of 18 . the test is considered as “Failed” and the procedure for failure treatment shall be applied.6) the Applicant/Participant may be present to witness. When the units are not recovered on time. by adapting the selection software to the test results. then it is considered as a component failure. which will immediately forward it to the Participant. Units shall be installed in test facility in accordance with the Applicant/Participant’s published installation instructions. For each performance item. testing and recrating the unit for shipment. The corrected software with its new version number shall be sent to Eurovent Certita Certification who will check the consistency of the modifications.
