Here's a U.S. official saying 9/11 was an "inside job" so this should realy show doubters who don't think THE gOV CARRIED OUT 9/11 www.infowars.com...

You should get a job at UL Howard because you obviously know more than those running the place!
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.
The first two tests, conducted earlier this month at the UL facility in Toronto, Canada, looked at the fire performance of 11-meter (35-foot) floor systems coated with a near-uniform 19-millimeter-thick (0.75-inch) layer of fireproofing material. This is representative of the span size and as-applied average fireproofing thickness of the floor systems in the WTC towers.
For the two experiments at UL in Illinois, 5-meter (17-foot) truss spans – the standard size used in U.S. fire resistance tests – were built. Both were restrained. The test on Aug. 19, 2004, was conducted on a floor system with a fireproofing thickness of 19 millimeters (0.75 inch), the same as the 11-meter assemblies tested in Canada. Yesterday’s final fire test used a 5-meter truss with a fireproofing thickness of 13 millimeters (0.5 inch). This was the thickness of the truss fireproofing originally specified when the WTC towers were built. Therefore, if an ASTM E119 fire resistance test had been conducted on the WTC floor system prior to construction, these would have been the test conditions. NIST has no evidence or record indicating that such a test was ever done.

Therefore, if the fireproofing was damaged or knocked off by the shock of the impact, the fire resistance rating as determined by ASTM E119 would no longer be valid.

Your so sure of yourself about defending the official story of 9/11 that it just seems personal rather than anything else. Are you defending this governments name? Is that your mission here?
I just don't understand the stubborness about 9/11 and don't really see you post anywhere else so i'm curious as to why this one is so important to you.
These reports are being issued in draft form with a six-week period for public comment. Public comments will be accepted during the period commencing June 23rd and ending at 5 p.m. EDT on August 4th.

Nice, link to NIST to disprove a someone at UL who wrote to NIST about their report being flawed.

I don't know how you can say the planes hit the fireproofing off, because the buildings didn't even shake when they were struck (so we could notice anyway)

And with the South Tower the fire didn't even spread to the other side of the building, so the plane would NOT of knocked off the fire proofing on the other side of the Tower, and for a pancake demolition you would need the whole floor to give way, not just half.
