scope:

The purpose of this NACE International standard recommended practice is to present procedures and practices for the design, installation, operation, and maintenance of deep groundbeds used for the control of external corrosion of underground or submerged metallic structures by impressed current cathodic protection. It is intended to be used in conjunction with NACE standards RP0169 and RP0177. This standard is intended to be used by corrosion engineers, corrosion consultants, representatives from manufacturers, and others concerned with corrosion control of underground structures.

This standard was originally prepared in 1972 by NACE Task Group T-10A-7, a component of Unit Committee T-10A on Cathodic Protection and was revised in 1985, 1995, and 2001. This 2001 revision was prepared by NACE Task Group 021 on Installation Methods for Deep Anodes. This Task Group is administered by Specific Technology Group (STG) 05 on Cathodic/Anodic Protection and sponsored by STG 35 on Pipelines, Tanks, and Well Casings. Task Group 021 is composed of corrosion engineers from oil and gas transmission companies, gas distribution companies, power companies, and communications companies as well as corrosion consultants, representatives from manufacturers, and others concerned with corrosion control of underground structures. This standard is issued by NACE under the auspices of STG 05.
