UNI 11734 : Determining fish-scale susceptibility of enameling steel

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.
