I think you should be able to find preferred series at least on some European sites. M Moon ------ Original Message ------ Received: Sat, 05 Feb 2005 10:18:16 AM PST From: "James R.

The distinction the author makes between gage and gauge is what I grew up with, though I have seen the two terms confused with little public complaint for some time now. I note that AWG is not listed. Some equate that to B&S, but he does not in his listing for B&S. One that is listed and sounds intriguing is ISO Metric Preferred Series (R388). I wish I could get my hands on that just to satisfy my curiosity. (I do have a copy of ASTM B258-02 on its way to me, courtesy of ASTM for the sake of our work in the joint IEEE and ASTM committee.) Notice, by the way, that the author of this site unabashedly leaves nekkid decimal points strewn about. Tut, tut.

I particularly like the writer's discussion of the spelling of gauge vs gage and then the definition of gage. 'Gage: An arbitrary assignment of numbers to size, used on sheet, wire, and many other things (tubing, shotgun bore, needles, and so on). Unfortunately there are so many different standards that using gage to specify a material is almost useless, and perhaps even dangerous. If in doubt, use decimals'. I would change the final sentence to read 'If in doubt use micrometres', but otherwise I agree that gauges (or gages) are relatively useless. By the way, I noticed that they made an error with respect to 'Card Wire Gauge CWG' which they say is for fibre yarns when it is, in fact, used for the specialised metal 'wires' that are used on the rollers and drums of carding machines. These are actually not circular wires but rather flattened strips of metal with raised pins designed to engage with textile fibres as they are being 'carded' (Note: Textile carding is a sort of rough combing process). -- James R.
