1.1 This recommended practice defines minimum physical quality and inspection standards for cast sacrificial anodes for offshore applications.
1.2 The objectives of this recommended practice are: (1) to standardize an industry-wide practice that can be used by consultants, manufacturers, and users to define the physical requirements of anodes; and (2) to be specific enough to assist the inspection authority in their task of confirming that anodes comply with the physical requirements.
1 .3 This recommended practice is applicable to the majority of anodes used on fixed offshore structures, i.e. ,cast anodes with circular or trapezoidal cross sections, with length substantially greater than width, and generally of a "stand-off' configuration (having extensions to the steel insert to achieve stand-off).
1.4 This recommended practice does not select particular anode alloy compositions or define short- or long-term performance tests.
1.5 This recommended practice does not specify particular anode or anode insert designs. An experienced corrosion specialist should be· responsible for anode and anode insert design. Particular attention should be addressed to NACE Standard RP0176 (latest revision).
1 .6 The manufacturer is responsible for meeting the quality levels specified in the recommended practice. The purchaser shall determine the extent of inspection to be conducted by the purchasing organization to prove compliance with the quality specified.
