Abstract
A method for determining at least one physical parameter of accumulator electrode plates, such as the true plate thickness P.sub.d, the apparent density D.sub.s of the active material, the true density D.sub.w of the active material, the pore volume P.sub.a, the porosity P.sub.0 of the active material or the pore structure, is performed such that, by means of various weighings, the weight (G.sub.FP) of a liquid plate is determined instead of the weight of a real electrode plate, and, from this value, the desired physical parameter is obtained which is used for controlling the production process.
