Description
This standard provides the minimum requirements for coal-tar protective exterior coatings and interior linings used in the water supply industry for buried steel water pipelines. AWWA steel pipe coating standards are written for and based on the service temperature of potable water. For operating temperatures higher than the normal temperature of potable water, consult the manufacturer for recommendations concerning temperature limitations for coal-tar protective coatings and linings. Major revisions made to the standard in this edition include the following: Sec. 4.2 was revised to include a requirement for NSF/ANSI 61 certification if a lining system is to be in contact with drinking water; former Sec. 4.4.7, Enameling of adhesive coated pipe after heating, has been deleted; former Sec. 4.4.9.8, Exterior coating system construction requirements, has been moved and included as part of Sec. 4.7.2, Additional exterior protection systems; additional requirements have been added under Sec. 4.7.2, Additional exterior protection systems; Sec. 4.8, Field procedures, has been rewritten; a new Sec. 5.3, Thickness testing, has been added; and a new Sec. 5.4.15, Cathodic disbondment, has been added.
