The small punch test technique was developed in the USA in the 1980 s, followed shortly by Japan and introduced to Europe in the 1990 s. CEN organized Workshop 21 to summarize more than ten years of research results and formulate the first technical guidelines CWA 15627. The specification work for European standard started in 2015 and the first European standard EN-10371 was published in 2022. The EN-10371 standardized the specimen size and test apparatus. It also specifies the test procedure and characteristic parameters for small punch test (SP) and small punch creep test (SPC). Nine annexes allows estimation of the values normally obtained using classical standard size uniaxial or fracture mechanics specimens. In order to make the standard perfect and usable, the standard working group proposed a five year “standard follow up” project in 2019. Responding to the proposed project, authors carefully re-examined the specification, and found some shortcomings in the standard. Proposals are put forward to improve the current methodology and extend the standard scope to include the latest development.
