The Italian Institute of Welding Group's Laboratory is able to perform tests for determining the creep behaviour of metals and plastics according to the methods described in different international standards (ASTM, ISO).

The testing procedures allow to observe the increase in deformation vs time, evaluating the deformation rate up to temperatures of 1100°C for metals and 205°C for plastics.

The purpose of a creep test is verifying and recording the behaviour of a parent metal or a welded joint with a certain applied stress at constant temperature. Further to provide a characterization of the material, the test results also allow to extrapolate the service life of a component up to 100’000 hours according to the most up-to-date calculation models proposed by the international codes (e.g. Omega Test Method - API 579, ASTM).
