The purpose of this recommended practice is to set minimum physical quality and inspection standards for cast sacrificial anodes for offshore pipeline applications. This standard is applicable to typical half-shell or segmented bracelet-type anodes and, although some aspects of this standard may be relevant to other types of sacrificial anodes, it is not intended to apply to platform, hull, tank, or extruded type anodes.

This recommended practice was prepared by Task Group T-7L-9 with the direction of Unit Committee T-7L on Cathodic Protection and published under the auspices of Group Committee T-7 on Corrosion by Waters. This recommended practice is complementary to NACE Standard RP0675 (latest revision) titled, "Control of External Corrosion on Offshore Steel Pipelines."

This recommended practice does not address electrochemical or other anode performance test procedures. NACE Task Group T-7L-2 on Aluminum Anode Quality Control has correlated a standardized, short-term potential and capacity determination test procedure for quality control purposes in international laboratories.<1l Also, NACE Task Group T-7L-7 is addressing long-term laboratory test procedures for performance characterization in a document titled, "Guidelines for Laboratory Performance Evaluation of Sacrificial Anodes."

 This recommended practice defines minimum physical quality and inspection standards for bracelet sacrificial anodes for offshore pipeline applications, including risers and J-tubes.
