Title: Sealant Testing Device
Description: Mounted on the roof of a building on NIST's Gaithersburg, Md., campus, this NIST-developed device is designed to induce temperature-caused strains on sealant specimens while monitoring loads and displacements. Affixed to a rigid base, the top segments of PVC pipe expand and contract with changes in temperature. Sensors, load cells, and specimens--sandwiched between aluminum blocks--are suspended from the top crosspiece, which moves, and are attached to the same rigid base. Weather tracking station is in the foreground.
