Abstract
A portable testing apparatus for a Brinell test meeting the load time requirements of the ASTM E10 standard. The apparatus incorporates a hydraulic accumulator acting on a cylinder which is connected to an indenter. The accumulator keeps a constant force on the indenter for the period of time of the test despite hydraulic leakage or creep of the indenter into the material that would cause a reduction in pressure if not for the accumulator. Usually, the test time length is 10 seconds. Pressure is set using springs usually in a settable sequence valve.
