Significance and Use

3.1  The rotating cage (RC) test system is relatively inexpensive and uses simple flat specimens that allow replicates to be run with each setup. (1-11).3

3.2  The RC method can be used to evaluate either corrosion inhibitors, or materials, or both. Guide G184 describes the procedure to use rotating cage to evaluate corrosion inhibitors.

3.3 In this test method, a general procedure is presented to obtain reproducible results using RC to simulate the effects of different types of coupon materials, inhibitor concentrations, oil, gas and brine compositions, temperature, and flow. Oil field fluids may often contain sand; however, this test method does not cover erosive effects that occur when sand is present.


1.1 This test method covers a generally accepted procedure to conduct the rotating cage (RC) experiment under atmospheric pressure.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
