Kevin Ryan : On Why NIST's 9/11 WTC Reports are False and Unscientific

[hack89]

6. In America, steel is not certified at all. Ryan was making shit up.

16. Was the steel in the WTC towers certified by Underwriters Laboratories (UL) to 1,100 degrees Celsius (2,000 degrees Fahrenheit) as some have claimed?

UL did not certify any steel as suggested. In fact, in U.S. practice, steel is not certified at all; rather structural assemblies are tested for their fire resistance rating in accordance with a standard procedure such as ASTM E 119 (see NCSTAR 1-6B). That the steel was “certified ... to 2000 degrees Fahrenheit for six hours” is simply not true.
