11、-2003 NACE International i _ Foreword 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 des
12、cribes 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
13、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
14、developed products which 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 deve
15、loped 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 first prepared in 1995 by NACE Task Group T-14C-7, a componen
16、t of Unit Committee T-14C on Rail Equipment Corrosion. It was reaffirmed in 2003 by Specific Technology Group (STG) 43 on Land Transportation. This standard is issued by NACE under the auspices of STG 43. In NACE standards, the terms shall, must, should, and may are used in accordance with the defin
17、itions of these terms in the NACE Publications Style Manual, 4th ed., Paragraph 7.4.1.9. Shall and must are used to state mandatory requirements. The term should is used to state something good and is recommended but is not mandatory. The term may is used to state something considered optional. _ RP
