HISTORICAL DOCUMENT. This standard recommended practice provides guidelines for qualifying personnel employed in the areas of surface preparation and coating and lining of railcar equipment. In order to assist growth and foster technical continuity in the industry, this standard describes a formal system of training and qualification which recognizes the skill and technical competency of the craftsmen employed.

Appendix A provides a list of recommended training sources for employers who are seeking to qualify personnel as abrasive blasters or coating and lining applicators in the railcar industry.

During the 1980s, coatings and linings used in the rail industry underwent substantial technical changes. Environmental quality standards and industry requirements for corrosion control and product quality demanded additional technical changes. Coating and lining manufacturers developed products that became increasingly more complex in their application requirements. Railcar equipment owners developed and implemented comprehensive quality programs requiring total conformance to their specifications. In addition, sophisticated equipment and inspection procedures were developed and utilized. During this progressive period, the need to effectively improve the skills of the craftsmen employed in surface preparation and coating and lining application evolved into an area of vital importance.

This standard was prepared by NACE International Task Group T-14C-7, a component of Unit Committee T-14C on Rail Equipment Corrosion, and is issued by NACE International under the auspices of Group Committee T-14 on Corrosion in the Transportation Industry.

1.1 The quality of a coating application depends primarily upon the capabilities of the people who are performing the actual work. This standard has been prepared to establish guidelines for the qualification of abrasive blasting and coating and lining personnel.  These jobs require appropriate knowledge of specific technical principles.
