Hence the requirement to use a (mostly) nitrogen atmosphere that is "modulated" with some (pure) water. But Mr. Richmond is very correct.
In any case, this was based on a mathematical representation found in a text book; which, rather too frequently, does not account for the non-ideal mechanics of the test. If reality and existence were as "purified" as indicated in an undergrad physics text, then society would not tolerate engineers... luck, Brian > -----Original Message----- > From: [email protected] [mailto:[email protected]]On Behalf > Of Cortland > Richmond > Sent: Wednesday, November 30, 2005 10:25 AM > To: ieee pstc list > Subject: RE: Environmental testing help > > > Brian O'Connell wrote > > >> According to my (old and dusty) physics text book, > supercooled water can > be present as low as -12C, so low-temp control may be possible. << > > This has got to be a tough one.
