This apparatus, is an impact tester, it's actually an ASTM standard test method that's used in the vinyl composition tile specification for evaluating the impact resistance of resilient floor tile. It's actually a measure of the tiles internal strength. The way the test is conducted, is you take a sample of tile, they scribe a three inch diameter circle on the center of that piece of tile. Then they will coat that with some zinc oxide paste, which helps at the conclusion of the test to evaluate for any cracks, fractures or breaking of the tile. Then mount that in the test equipment, face down, such that, that three inch diameter circle, is really unsupported. It's, it's only supported the tile support on three balls around the edges. So the center section is really unsupported. Then they turn the test on, and they drop these one inch diameters steel balls. They weigh about two and a quarter ounces. It doesn't sound like a lot but. [NOISE] When you drop one of those bad boys, it, it can do some damage. So the samples mounted in the tester. We'll turn that on, [NOISE] it'll run four drops. And the specification requires that the tile can survive four drops without any cracks or breaks in the tile, that would extend outside that three inch diameter circle. Now you can see it after four drops, there's actually no evidence of any damage. So, we can put that back in. You know, typically, you know, we'll make sure we meet the requirement and the spec which is four drops, [SOUND] but it's not necessarily uncommon for us [SOUND] to sometimes [SOUND] run this to failure. [SOUND] There was another six or seven drops and still we're not seeing any damage on the tile. Actually this happens to be a sample of one of our Migrations bio-based tile, which has outstanding impact.
