Innovation Hub
Innovation Hub belongs to the Support Operations Division of PPC S.A. (Public Power Corporation S.A.). Until recently it was widely known in the Private and Public sector as “Testing Research and Standards Centre”. The Center’s activities include the provision of services not only to the units of PPC Group but also to external customers; namely large organizations of the Public and Private sector. The services provided include tests in Hub's laboratories, accreditation, research, consulting, inspections, instrument calibration, implementation science and analysis, as well as quality control through inspections on materials and technical equipment, new or used. Hence, the Hub’s activities are extended so as to satisfy the need for high scientific level research and to deliver services of highly specialized requirements. It should be noted that all the aforementioned activities can be conducted with safety and reliability in the facilities of Innovation Hub, in customer’s premises or elsewhere, where the examined object might be situated. Innovation Hub is accredited by the Hellenic Accreditation System (E.SY.D) according to ISO standards 17020 and 17025. To preserve the validity of accreditation, Innovation Hub is subjected to regular and thorough inspections by E.SY.D. In that way we monitor not only the level of Hub’s operational efficiency, but also get evaluated upon the tests’ and inspections’ reliability and accuracy.
