The state-of-the-art review conducted by RINA in Work Package 2 (WP2) highlighted the tests and standards to be used for this environment, as well as the compatibility of metals with hydrogen.
The tests are defined and carried out in Work Package 3 (WP3). The first task was to define the various materials to be tested, as well as the testing machines, depending on the availability of each partner equipment. The second part of this WP involved creating a test matrix, composed by a round robin test and individual tests. The round robin (RR) tests will be conducted by multiple partners for comparison, while the individual tests will be performed independently by each partner. For both RR tests and individuals test, statics loaded test as C-Ring with and without notch and CT-WOL specimens will be carried out by FHa, RINA and GRTgaz. Dynamic loaded tests as fatigue crack growth tests, SSRT with and without notch and Fracture toughness tests will be done by RINA, GRTgaz and Tecnalia.
In total, 14 materials will be tested, including vintage and new materials. All new and vintage materials will be collected by SIDSA, from Redexis, Itaglas and Inrete distribuzione and then distributed to RINA to machine the specimens for the RR tests and to the other partners for the individual test. Base metal and a weld will be tested.
This report details the initial and final test matrix, explaining the modifications that had to be made due to constraints related to material thickness or testing machine. It also explains the purpose of each test, as well as the testing parameters and standards that will be applied within the framework of CANDHy.
