""UL does not certify structural steel, such as the beams, columns and trusses used in World Trade Center," said Paul M. Baker, the company's spokesman.
Ryan was fired, Baker said, because he "expressed his own opinions as though they were institutional opinions and beliefs of UL."
"The contents of the argument itself are spurious at best, and frankly, they're just wrong," Baker said.

"Merely being affiliated with a company such as UL does not make one immune to becoming a conspiracy theorist. In any event, Ryan was not directly employed by UL; he was an employee of Environmental Health Laboratories, which is not, as he claimed, a division of UL, but merely affiliated with UL (as many companies are). UL released a public statement saying that they do not certify the steel materials for buildings, and that Ryan was fired for making his absurd and inaccurate comments. No credence should be given to anything Ryan said in his letter. "

"Kevin Ryan is not an “expert” in the matters about which he spoke. Kevin Ryan is merely a “chemist” who was employed to study “water” at a division of Underwriter's Laboratories. [This and other easily verified facts ought to be mentioned in any subsequent articles about “loose change”]
Kevin Ryan committed deception and was justifiably fired. Kevin Ryan falsely asserted:
“We know that the steel components were certified to ASTM E119. The time temperature curves for this standard require the samples to be exposed to temperatures around 2000F for several hours. And as we all agree, the steel applied met those specifications.”
Apparently, because it did not suit his DECEPTIVE PURPOSES, Dylan Avery did not bother to look up what the ASTM E119 standard actually is. ASTM E119 does NOT test “steel” nor “steel components” per se as Mr. Ryan had implied. Rather, ASTM E119 time-temperature tests evaluate whole building assemblies that include fire-proofing or fire-resistance:
“ASTM E119, Standard Test Method for Fire Tests of Building Construction and Materials, is used to determine the fire resistance of a complete assembly. For example, a wall system fire rating is measured by constructing a 10 foot by 10 foot section of a total wall system: framing, cavity insulation, sheathing, siding, gypsum wall board, etc. The wall section is installed vertically on a gas furnace, and the wall is exposed to a standard temperature curve for the time period for which a rating is desired, i.e., one, two, three, or four hours. Failure points during time of fire exposure are:
“• Flame penetration through the wall section;
“• An unacceptable temperature increase on the unexposed side of the assembly;
“• Structural failure or collapse of the assembly.
“Therefore, a one hour fire resistance rating is taken to mean that a structure incorporating the tested wall construction will not collapse, nor transmit flame or a high temperature, while supporting a design load, for at least one hour after a fully developed building fire.”

The chemical and physical or thermal properties of the framing steel members are standardized and known, or are tabulated in catalogues, and determining such are not the object of the ASTM E119 testing. Rather, it is the functionality of the fire-proofing or fire-resistance of the whole assembly that is tested. After you crash an airplane into a building, the ASTM E119 test results become totally irrelevant, because you have changed the structure, at least by removing the fire-proofing or the fire-resistant wall and ceiling materials. [Accordingly, UL spokesman Paul M. Baker stated, "UL does not certify structural steel, such as the beams, columns, and trusses used in the World Trade Center"] The ASTM E119 certification is intended to estimate how long the structural steel WILL BE PROTECTED FROM EXPOSURE to temperatures around 2000F.
