A laboratory procedure for determining the potential and current capacity characteristics of aluminum alloy anodes used for cathodic protection. Historical Document 1990
This standard test method describes a quality assurance procedure for determining the potential and current capacity characteristics under laboratory conditions for aluminum alloy anodes used for cathodic protection. Field performance of anodes should be evaluated to correspond to actual anode performance. This procedure was established in 1977-78 with revisions in 1980, 1982, and 1985. The committee knows of no NACE entity that has issued a comparable test method.
This test method was prepared by NACE Task Group T-7L-2 on Aluminum Anode Quality Control, a component of Unit Committee T-7L on Cathodic Protection in Natural Waters, in conjunction with ASTM( 1l Task Group G01-09-02 T-1. This standard is issued by NACE under the auspices of Group Committee T-7 on Corrosion by Waters. These committees are composed of industry representatives, including producers, consumers and interested individuals.
1.1 This standard test method describes a laboratory procedure for determining the potential and current capacity characteristics of aluminum alloy anodes used for cathodic protection. It provides a means for screening various heats or lots of anodes to determine performance consistency on a regular basis from lot to lot. In utilizing this test method, items such as sampling frequency and performance criteria (i.e., test values at intermediate times) are left to the discretion of the user of the test method.
1.2 One method for anode potential evaluation and two methods for current capacity evaluations are described.
