Here is the list of testing reports that Mark Piepkorn put together plus what I received from  
other people. I did not add the info from TLS 31, figuring that Chris and Joyce will have  
access to that in digital form.

Anyway, I'm of to Belgium in a few days to help Harald Wedig build a SB demonstration  
project, ordered and payed for by the European Union. It will be buildt during GreenWeek in  
the heart of Brussels, the beautiful city where the beer is good, the fries soft and greasy and  
where that little guy (Maneke Pis) is taking a leak to amuse the tourists. 

Greetings to you all,

Contains, among other things, results of a thermal-flow test that most 
rational people seem to feel is flawed or jimmied. I'm not necessarily 
rational, but I am skeptical of the report.

Our project, financed by the Austrian Ministry for Traffic, Technology and 
Innovation and in cooperation with GrAT (Group for Appropriate Technology at 
the University of Technology in Vienna) is finished: 
So the tests we made are available soon in original (I will tell you as far 
as you can get the original tests). 

Concerning a full scale fire test for a straw bale building it was interesting for me to visit the  
report and video-presentation of Dr. Vahik Enjily from the Centre for Timber Technology  
and Construction, Building Research Establishment, UK (BRE: <A
HREF=http://www.bre.co.uk)>www.bre.co.uk)</A> in Vienna.
BRE built a six story timber and frame building in a hangar and made a lot of (full-scale-)fire  
tests under regular circumstances. The results are gathered in a study and are very interesting,  
I think.
Now I believe (even when you build loadbearing) fire performance of strawbale houses is  
similar to timber & frame constructions because of the similar material (cellulose). Even our  
strawbale-wall-firetest (90 min. fire resistance for a plastered strawbale wall) showed results  
that are similar to other (insulated) timber and frame construction-fire tests, we know of. If  
you are interested, I could send you a copy of the study of BRE, or you wait #180#til it is  
published online.

As offical tests and certificates are very important to convince officals and reduce prejudices  
we are planning to collect all available tests and certificates and put 
them on our homepage (<A
HREF=http://www.grat.tuwien.ac.at)>www.grat.tuwien.ac.at)</A> to make them available for all straw bale  
builders. Although at the moment the website is restructured and will be in the 
net by end of this year, this e-mail is an invitation to all straw balers, who have already done  
offical (and also inofficial) testing, to support our intentions and 
send us informations about the tests and/or offical certificates.

I wonder if you have the New Mexico fire test results, of a successful 2-hour SB test to  
ASTM standards... I could fax you the 5 or 7 pages if you need them right away.

Also, a relatively new SB "Flame spread and Smoked developed fire test" was done last year  
and the results are very good. These have just been posted to the DCAT (Development  
Center for Appropriate Technology) website at: <A
