It looks like it, the data sheet and the makers website are unclear on it but they list 16/10 8/10 4/10 and 2/10 (special order) which does correlate well to standard PCB thicknesses, 1.6 0.8 etc...
This 10th thing must be a french thing, to me fractional sizes hint that the unit is inches, but the frech have been using metric measurement for longer and so I find 16/10 being 1.6mm plausible.
I hink you mean:
