Resumen
Specifies a procedure for the measurement, under non-equilibrium conditions, which has been shown by practice to give a reliable indication of the presence of hydrophilic compounds. This tension is determined by measuring the force necessary to detach a planar ring of platinum wire from the surface of the liquid of higher tension, that is, upward from the water-oil interface.
