Final report on WIPANO research project - A new test method for evaluating prestressing steels' susceptibility to stress corrosion cracking

  • For the safety of prestressed concrete structures, a test of prestressing steel products for hydrogen-induced stress corrosion cracking is mandatory. The current standardized test methods according to DIN EN ISO 15630-3 have proven deficiencies concerning the reproducibility of the results and thus make it difficult to assess the susceptibility clearly. The WIPANO research project funded by BMWK aimed to improve the test method regarding reproducibility and reliability of results. The project created constant and reproducible test conditions by modifying material, electrolyte, and process parameters. This allowed a clear differentiation between good and bad products. As part of the project, a round robin test was initiated to confirm the applicability and reproducibility of the new test method. The new test method was evaluated for its applicability to the prestressing steel product wire. A draft standard with a proposed conformity criterion for these products was submitted to theFor the safety of prestressed concrete structures, a test of prestressing steel products for hydrogen-induced stress corrosion cracking is mandatory.

The new test method was evaluated for its applicability to the prestressing steel product wire. A draft standard with a proposed conformity criterion for these products was submitted to the responsible ISO committee for approval. According to the current feedback from the committee, the draft standard will be included in the informative annex of the testing standard, which could pave the way for mirroring at European and national standardization levels.zeige mehrzeige weniger
