New NIST Testing Device May Help to 'Seal the Deal' for Building Owners

Caption

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.
