Want this as a site license? Scope 1. Calculation methods for converting corrosion current density values to either mass loss rates or average penetration rates are given for most engineering alloys. In addition, some guidelines for converting polarization resistance values to corrosion rates are provided.
No other units of measurement are included in this standard. Significance and Use 3. This practice is intended to provide guidance in calculating mass loss and penetration rates for such alloys. Some typical values of equivalent weights for a variety of metals and alloys are provided. The conversion of these results to either mass loss or penetration rates requires additional electrochemical information.
Some approaches for estimating this information are given. This will make results from different studies more comparable and minimize calculation errors that may occur in transforming electrochemical results to corrosion rate values.
