review of Didas paper Reference: Didas, J. L., "Practical Applications and Limitations of Buried Coupons Utilized for IR Drop Measurements", Corrosion '97, NACE Paper No. 572.

Review: This paper is a collection of opinions about the use of coupons as a tool for monitoring cathodic protection systems. The opinions expressed in this paper are a good summary of the findings and conclusions of several published studies on the subject. However, Didas does not reference these studies.

Only one disadvantage is listed:

Good engineering practice demands that a number of issues be considered when implementing the use of coupons to monitor cathodic protection systems. Didas briefly discusses seven such issues:

The design considerations listed in this paper are:
