Varför skulle kevin Ryan veta något om stål?? Han var en kemist som arbetade som vattenanalytiker på Environmental Health Laboratories (ett dotterbolag till UL). Hans påståenden att UL ”testade” stålet för WTC har förnekats av både Nist och UL själva…
Environmental Health Laboratories is a company, which offers laboratory facilities for chemical and microbiological analyses of drinking water. It helps public water supplies comply with Safe Drinking Water Act regulations and assists environmental professionals in understanding changes in the industry.
The company said Ryan "was not involved in that work and was not associated in any way with UL's Fire Protection Division, which conducted testing at NIST's request."NIST:
The company said it "fully supports NIST's ongoing efforts to investigate the WTC tragedy. We regret any confusion that Mr. Ryan's letter has caused 9/11 survivors, victims' families and their friends."
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.
