This NACE International standard is specifically targeted for use by tank car owners, operators, and repairers who are seeking guidance in complying with federal regulations regarding interior coating/lining condition data collection and analysis. This standard provides guidelines for inspecting, rating, and documenting the condition of interior coatings and linings in tank cars. Additionally, procedures for determining disposition of coatings/linings in various stages of distress are outlined, as well as a mechanism for constructive reaction when it becomes apparent that interval lengths require adjustment. There are three nonmandatory Appendixes that provide an example of a coating condition ratings system; an example of a disposition schedule based on the example coating condition rating system; and an example of a coating inspection form as well as a tank car map. It should be noted that issues similar to those discussed here may arise with other bulk liquid transportation containers, and this document may find applicability in those areas as well.
