Talk:International Annealed Copper Standard

Creation

I created a page for this topic because the standard is used in industry as a means of specifying conductivity values for metals. This is my first article and I hope it is acceptable. Because the original standard was readily available on the web, I simply used it to write the article which is somewhat short, especially in regard to the current use of the standard. Hopefully, more can be added by those familiar with the modern use of the IACS standard.

Agreed. I work for an aerospace company and use the IACS conductivity scale on a regular basis to verify the proper heat treatment of aluminum alloys. I came to this page because I was discussing the history of the standard with one of our younger materials engineers and needed a quick reference. This standard is used across the aluminum alloy industry. I'll see what I can do to expand the article to make it more relevant. Mmyotis ^{(^^o^^)} 20:06, 14 April 2016 (UTC)

standard / standard / standard

Care should be taken not to confuse the several meanings of how the word is used:

1. An abstract reference (e.g. IACS)
2. An actual instance of an object against which others are compared (e.g. Gauge block, the original kg "prototype")
3. A regulation (e.g. law, IEEE, IEC)
4. A de facto situation (e.g. the standard of living)

See the confusion with the term "working standard" which is used to describe a pound weight and a minimum wage law

Error

In the third paragraph:

..., this being equivalent to a conductivity of exactly 58 S/m.

shouldn't it be 58 MS/m? Read here: https://www.nde-ed.org/GeneralResources/IACS/IACS.htm or calculate with density 8890 kg/m^3. — Preceding unsigned comment added by 193.2.15.1 (talk) 17:17, 23 May 2017 (UTC)

Heat treatment of aluminum alloys

Well, this is all very interesting, and thanks for the link to "totalmateria.com". But really this has nothing to do, at all, with IACS. All of the process described would work just as well if Ohm or Siemens were used. (Arguably even better, as the measurement process will certainly be using Volts and Amperes, and the measured results can be calculated easier, without need for extra interpretation by consulting an artificial standard.) The only valid point is that the ASTM obviously still publishes IACS values instead of using the proper modern SI units. Other than that there is absolutely no connection. All this stuff should probably go into either heat treatment or something about aluminium alloys. In the meantime I have also tried to whittle it down to the relevant core information. --BjKa (talk) 14:34, 27 April 2017 (UTC)
