I mean, why not 90C or 130C, or 91C or 131C?or 80C or 120C? Why 85C and 125C? How did this particular temperature range become the industrial standard? | |

May 29, 2016 at 7:40 | comment | added | coteyr | I can add to this by saying (admitting) to several times frying a peace of non-trivial electronics by leaving it on or out while in a car in FL. Many CD players, laptops, MP3 players, etc., all ruined because a normal car, in direct sunlight, with the windows up on a summer day would exceed normal temperature ranges. Now replace car with tank, and hot FL summer with Hot Iraq Summer..... | |
