The Italian National Unification institute has published UNI 11734 as of December 6, 2018.
This standard specifies a method for measuring the hydrogen diffusion coefficient in order to determine the fish-scale susceptibility of steels, which can be used in the enamelling process.
The standard applies to low carbon and decarburized cold-rolled steel, which has been calmed with aluminum in a thickness range of 0.30 mm to 1.20 mm.
The associated equipment, mentioned in the new standard & shown below, is fully described at this webpage.
