The ETA (European Technical Assessment) for X-fix C is ETA-18/0254 is valid since 2018.05.07. The ETA-18/0254 for X-fix C was issued by the the Austrian Institute of Construction Engineering.
Recent Tests in October 2017 at Graz University of Technology have shown, that the improved version of X-fix C has a 30% higher tensile strength and shearing resistance than originally stated in the 2016 Graz Technical Report due to higher manufacturing accuracy.
X-fix L and X-fix C were tested by the Competence Center of the Graz University of Technology holz.bau-research GmbH and on this basis also the basics for the static design of DI Manfred Augustin of holz.bau-research GmbH were developed.
The mechanical properties strength and rigidity of the wood – wood joint systems X – fix C and X – fix L are described in the report No. GU16-484-1-01 of the Lignum Test Center (LTC) TU Graz, Univ. Prof. DI Dr. Gerhard Schickhofer stated. This report allows the use of X-fix L and X-fix C after static calculation. The ETA for X-fix C is expected in spring 2018.
