Standard Test Method for Determination of Corrosion Rate in a Water System in the Absence of Heat Transfer (Weight Loss Method)

Importancia y uso:

4.1 Since the two tendencies are inseparable for a metal to corrode and for water and the materials it contains to promote or inhibit corrosion, the corrosion rate of a material in water is determined in relative, rather than absolute, terms. The relative tendency for a material to corrode is determined by measuring its rate of corrosion and comparing it with the corrosion rates of other materials in the same water environment. Conversely, the relative tendency of water to promote or inhibit corrosion can be determined by comparing the corrosion rate of a material in the water with the corrosion rates of the same material in other waters. Such tests are useful, for example, for evaluating the effects of corrosion inhibitors added to the water. Examples of systems in which this method can be used include, but are not limited to, open recirculating cooling water, closed chilled water, and hydronic heating systems.
