AWWA C203-25 Coal-Tar Protective Coatings and Linings for Steel Water Pipe and Fittings
The purpose of this standard is to provide the requirements for hot-applied enamel and tape coal-tar protective coatings and linings for steel water pipe and fittings, including materials, application, inspection, testing, performance requirements, packaging, and storage requirements.
Description
This standard provides the minimum requirements for coal-tar protective coating and lining systems used in the water supply industry for buried steel water pipe and fittings.
1.1.1 Maximum temperature. AWWA steel pipe coating and lining standards are written for and based on the service temperature of potable water. Consult the coating manufacturer for conditions and limitations.
1.1.2 Conditions not described in this standard. The coating systems described in this standard are not intended for use on pipe that will be bent after the coating or lining system has been applied.
1.1.3 Other substrates. When this standard is referenced for substances other than carbon steel, the surface preparation methods, application methods and performance data listed in this standard may not be applicable and the coating manufacturer should be consulted.
This standard can be referenced in purchase documents for hot-applied, coal-tar protective coatings and linings of steel water pipelines. The stipulations of this standard apply when this document has been referenced and then only to protective coatings and linings of steel water pipelines with hot-applied, coal-tar enamel systems and to hot-applied, coal-tar tape on the exterior of special sections, connections, and fittings.
