This standard practice describes overcoating of the exteriors of railcars. The purpose of this standard practice is to provide methods for testing and application of overcoating materials for the benefit of railcar owners, lessees, and maintenance providers who are charged with developing and executing programs for the maintenance painting of railcars.
This AMPP standard is specifically targeted for use by tank car owners, operators, and repairers who are seeking guidanceincomplyingwithfederalregulationsregardinginteriorcoating/liningconditiondatacollectionandanalysis.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.
This standard practice encompasses the requirements for expert application of a quality coating system to exterior surfaces of steel rail cars that have been prepared in accordance with a specified, recognized standard. It is intended to complement NACE SP0386 and NACE SP0295.
Qualified inspection of the completed coating system and testing by the use of adequate, readily available instruments are also covered in this standard. Coating manufacturers, coating applicators, and those who have contracting authority for rail car coating installation should be able to use this standard to determine the facilities, equipment, and personnel needed to satisfy the requirements for rail car exterior coating systems.
