1. Scope

1.1 This standard specifies the requirements for application, method of sampling and test and handling of materials of solventless liquid epoxy system for application on interior and exterior surfaces of steel water pipelines, installed underground or underwater, under normal construction conditions, for corrosion protection.

1.2 It is suitable for application by airless spray or plural component system machine. It is not intended for use on pipes that will be bent after coating.

1.3 Solventless system consists of two components; epoxy resin and hardener mainly amide/amines.
