I had the same question. I Asked an independent retailer of door fittings about the fitting of a reasonable quality zinc alloy handle on an exterior door. He informed me this is pretty much the norm, just stay clear of the cheap £8 aluminium handles. So it seems the answer is yes, despite the info on all of these zinc alloy handles to suit a euro or 5 lever mortice lock saying 'interior use only' I guess the warranty may be void tho.
