Qualificazione dei grandi laboratori Europei di ricerca di ingegneria sismica
Networking Activity No.2 of the SERIES Project addresses the qualification (in the form of mutual accreditation) of European laboratories specialising in earthquake engineering and equipped for structural testing large scale structures. SERIES is a project ("Seismic Engineering Research Infrastructures for European Synergies") funded by the European Community in the 7[sup]th[/sup] Framework Programme – Infrastructures (FP7/2007-2013) under grant agreement n° 227887.
The ultimate aim of qualification is to provide reliability. Experimental activities should be repeatable, i.e. replicating tests on the same specimen in the same laboratory should lead to the same results, and reproducible, i.e. replicating tests on the same specimen in different laboratories should lead to the same results.
It is expected that the accreditation of European earthquake engineering infrastructures will enhance their standing, promoting a unified EU policy on acceptance criteria for products and techniques.
Within this framework, the SERIES project is developing a Common Protocol for the qualification of Research and Technological Development infrastructures covering seismic testing with multi-axial shaking tables, quasi-static and pseudo-dynamic techniques or hybrid experimental & mathematical modelling techniques.
The activity was broken down in four Tasks:
  1. Evaluation and impact of qualification of experimental facilities in Europe
  2. Assessment of testing procedures and standards requirements
  3. Criteria for instrumentation and equipment management
  4. Development and implementation of a common protocol for qualification.
After completion of the first three Tasks the following issues were identified:
                     Qualification of an RTD infrastructure in earthquake engineering implies a process different from the qualification of a Conformity Assessment Body.
                     International or European Standards dealing with certification or accreditation are not specifically devoted to the RTD laboratories.
                     Lack of International or European standards or regulation requesting the qualification of RTD infrastructures.
                     Lack of international recognition of the large capacities and associated human resources of the European RTD infrastructures.
Moreover, the following obstacles should be overcomed:
                     Lack of specific Standards for the qualification of RTD infrastructures;
                     Lack of specific Standards covering special seismic testing with multi-axial large shaking tables, quasi-static and pseudo-dynamic techniques or hybrid experimental & mathematical modelling techniques;
                     Lack of a qualification-oriented mentality of the high level management of the RTD infrastructures;
                     Underestimation by the laboratory staff of the benefits of an official qualification of the RTD infrastructures;
                     Reduced investment capabilities of RTD infrastructures.
The partners of the SERIES project have developed a draft of the Common Protocol adopting the general management and technical requirements of EN ISO/IEC 17025 together with EA 2/15 to obtain a ‘flexible scope’ accreditation.
The Common Protocol includes technical annexes dealing with Specific Technical Requirements for the performance of research tests for Shaking Tables, Reaction Walls and On-site Testing. The draft of the Common Protocol was calibrated by six laboratories (Athens, Trento, Naples, Skopjie Universities, JRC Ispra, CEA Paris), allowing at the end of the project to converge to a Common Protocol that will be applicable to similar infrastructures all through Europe.
After the completion of the audits three activities of the RTD Facilities were identified and the qualification may thus be achieved:
      for the Research Engineering Activities by the certification of the Management System after ISO 9001;
      for the Measurement Activities by the accreditation of the Laboratory after ISO/IEC 17025;
      for the Research Testing Activities by the accreditation of the Laboratory after ISO/IEC 17025 with flexible scope.

This proposal for the qualification of large research infrastructures was presented to the Laboratory Committee of EA in Oslo and to the 1[sup]st[/sup] ERNCIP Conference in Ispra.
