This standard recommended 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 Standard RP0386. 1 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 hopper car internal 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.

This NACE standard was originally prepared in 1992 by Task Group T-14C-2, a component of Unit Committee T-14C on Rail Equipment Corrosion. It was reaffirmed by Unit Committee T-14C in 1997 and is issued by NACE under the auspices of Group Committee T-14 on Corrosion in the Transportation Industry.

1.1 This standard describes procedures for the application of a coating system to the exterior surfaces of steel rail cars. The procedures cover all rail cars in general; however, some sections apply to a particular type (e.g., hopper, tank car).

1.2 The requirements for surface preparation, coating application, inspection, and quality tests necessary for externally coating a rail car are covered in this standard.
