n (1) In the Izod, Charpy and tensile-impact tests, a subtraction of the kinetic energy imparted to the broken-off part of the specimen. (2) In measurement of Dilute-Solution Viscosity a correction for the energy required to accelerate the liquid in the reservoir to its higher velocity in the capillary. A similar correction is theoretically needed in melt rheometry, but has so far been found to be much smaller than the errors of measurement.
