Maybe this article should be split into two articles, one about engineering and one about biology. The section about mammals seems out of place. And, for what it's worth, mammals aren't the only warm-blooded animals around.199.212.11.86 (talk) 02:57, 3 March 2010 (UTC)[reply]

Although it isn't a major issue, I think we should decide here whether this page should be written with British or American English. I think this should be written in American English i.e. "minimized" because there is no reference to anything related to the UK and there is a reference to the US military. Once we decide, we should put a "Use xxxx English" template on the page. Ryan Vesey (talk) 06:03, 18 May 2011 (UTC)[reply]

are manufactured in several grades:--Citation needed|date=January 2010--

I have a link http://www.altera.com/devices/common/ind/ind-temp.html where 5 grades are defined for chips. `a5b (talk) 07:35, 12 February 2012 (UTC)[reply]

The list currently defined on this page appears to be specific to one manufacturer; does not conform to broadly accepted typical ranges which are:

    commercial 0 to 70 C
    industrial -40 to 85 C
    military -55 to 125 C

for example, see http://www.eurotech-inc.com/info/pdf/calce-temprange-pcaoct01.pdf. Manufacturers can produce components that extend these ranges, but for analysis or costing purposes these are the typical ranges. Tjcognata (talk) 18:50, 15 September 2014 (UTC)[reply]

There is a link here regarding operating temperatures of internal combustion engines. The ranges give don't have any meaning in that sense. I believe, though, that as written they are typical cases, and one should not consider them the only possibility, though I believe that commercial and military are usual. I remember some years ago, when the military found out that -55C isn't always enough, when building devices to go outside missile factories in Siberia. It seems that Siberia in winter is colder than -55C. Gah4 (talk) 23:15, 24 October 2017 (UTC)[reply]
