[Ekodum]NIST data on insulation properties (fwd)

[Jan Hollan]

apropos, doslo to nekomu pres strawbale-l? Me ne, tak nevim, jestli to tam
mam poslat znova... (odpovezte prip. mne, ne do listu). dik, jenik

A plenty of measurements of insulation properties of most various
materials are available on the NIST server, so not in France, but in the
USA. The database is 
   http://srdata.nist.gov/insulation
 -- just give ``straw'' as a material and three results from 1949 (!) will
appear (two for a standard winter case, one for a sauna perhaps). The only
missing value is the bulk density, perhaps it has been a bit lower than
that needed to get conductivity below 0.040 W/(m.K). But still, 0.045 is
good enough!

My favourite URL for NIST is this one:
   Linkname: The NIST Reference on Constants, Units, and Uncertainty
        URL: http://physics.nist.gov/cuu/index.html
 -- unlike the commercial BIPM in Paris, they give a lot of very useful
information to all the world, God bless America!

schöne Grüße,
 Jenik

PS.
 I started searching the URL anew (I tried some months ago already,
unhappy that don't see this important reference in my lynx bookmark
files) by giving a string 
  thermal conductivity 
 to
  http://search.nist.gov
 and interesting results appeared, but then I decided that I perhaps have
 the URL stored somewhere and found it by grep in my netscape bookmarks, 
  grep -i NIST .netscape/bookmarks.html
 fortunately. Thanks to your question following my remark on the
gathering, I found it again...
