They test it under every adverse condition. UL was the lab testing the steel and other materials being used in the WTC. Electrical wiring, etc

Actually the burden of proof is on you. UL has stated more than once that they did not have anything to do with certifying the steel during the construction of the WTC.

no, UL tested the steel as part of the NIST investigation AFTER the collapse.
NIST Investigators Say WTC Steel Met Standards
A new report from the U.S. National Institute of Standards and Technology (NIST) suggests that the steel beams inside the World Trade Center’s Twin Towers met or were stronger than design standard requirements. Officials have tested some of the 236 pieces of steel from the debris, and while they maintain the report is preliminary and more testing is planned, they are confident that these initial assessments will be confirmed. The steel beams used to build the WTC were typical of materials in the 1960s when the towers were erected.

Now, I don't know who certified steel back in the '60s but someone did.
Does it matter if it was UL or not?

Do you know anything about the strength standards and all that for the 1960's steel compared to UL's standards?
