Jim, As it is snowing hard and I am one of 3 people in my building right now,
I don't remember 853 ever havbing a certification on it. It is airhardening, but it has been used pretty successfully for lugged frames, You don;t get the hardening benefit, but it still is prettuy high quality steel even without the hardening. I can't remember my source on that though. I worked with a bunch of 853 when I apprenticed at Kelly 13 years ago or so and I don't think there was a test at all to get it, just buy it and watch it tear through your holesaws and realize you need to buy better ones for this stuff, hard thinwall tubes are a bit tricky compared to older steels. (similar behavior to the ox Platinum TT sells). I don't remember the first generation of 853 (probably at the same time that waterford was building riv frames) being suitable dimensions for existing lugs either... My two cents.
