Abstract:
1. A method comprising: exposing an object made of metal to a flow of corrosive liquid, wherein the object has measurable dimensions such that the object may be subjected to direct measurement for determining a known surface area; determining the known surface area of the object from the measurable dimensions; withdrawing an effluent stream from the flow of said corrosive liquid after exposure of the object to the corrosive liquid; passing said effluent stream such that the effluent stream includes a concentration of metal from said object into an analysis device to determine a concentration of the metal within the effluent stream after the object is exposed to the corrosive liquid; and determining a corrosion rate of the metal within the effluent stream based on the known surface area of the object and the concentration of the metal within effluent stream as measured by the analysis device, wherein the corrosion rate is determined for each of two distinct time intervals independent from one another and without opening an autoclave in which the object is disposed and for each of two distinct time intervals having different processing parameters from one another.
