The scope of this standard is to establish minimum requirements to ensure proper application, inspection, and performance of a field-applied liquid coating system for field repair, rehabilitation, or girth weld joints on buried, external steel substrates. Included are methods for qualifying and controlling the quality of a liquid coating system, guidelines for its proper application and inspection, and repair techniques to ensure its long-term performance. The coating in the standard can be applied to girth weld joints during the construction of buried pipelines and their appurtenances that are used for conveying liquids or gases. The coating system shall consist normally of one layer of liquid product, applied by brush or by a spray technique. Other application methods (spatula, injection, spreading, etc.) can be recommended by the product supplier, in accordance with the product requirements.
