Assembly suitable for determining a coefficient of moisture expansion of a workpiece

摘要

An assembly for determining a coefficient of moisture expansion of a single, identified workpiece or coupon. The assembly includes means for positioning the workpiece in a chamber having known environmental parameters; means for determining a workpiece length change, DELTA L caused by a chamber induced change in the workpiece's moisture content DELTA M; and, means for measuring a chamber-induced change in the workpiece's moisture content DELTA M.
