ISO 18796-2:2025

This document specifies selection criteria and minimum requirements for selection of coatings for pressure service inside production vessels. These criteria are given for the following: — key factors influencing coating selection; — generic composition of test liquids that can be used as a reference when evaluating test evidence supporting coatings; — main test methods to be used as proof of performance when selecting appropriate coatings; — ensure that supporting evidence used in the evaluation of coatings is relevant to the potential end use. This document refers to types of materials that are generally available and have known and documented properties. It also allows other materials to be evaluated and qualified for use. This document must be used for coated production vessels during the construction phase of new equipment. It is intended for use only when the coating is applied directly to the substrate. This document does not cover requirements for metal coatings or weld cover materials.
