This NACE standard recommended practice provides the most current technology and industry practices for the use of plant-applied, coal tar enamel external pipe coating systems. This standard is intended for use by corrosion-control personnel, design engineers, project managers, purchasing personnel, and construction engineers and managers. It is applicable to underground steel pipelines in the oil and gas gathering, distribution, and transmission industries. This standard was prepared by NACE Task Group T-10D-2 on Coal Tar Enamel Coatings, a component of Unit Committee T-10D on Protective Coating Systems. It is issued by NACE International under the auspices of Group Committee T-10 on Underground Corrosion Control.

1 .1 This standard presents guidelines for establishing minimum requirements to ensure proper application and performance of a plant-applied coal tar enamel system to the external surfaces of pipe. Included are methods for qualifying and controlling the quality of a coal tar enamel (CTE) system, guidelines for its proper application, and inspection and repair techniques to ensure its long-term performance.

1.2 This standard is applicable to coating systems used to prevent corrosion in conjunction with cathodic protection.
