Standard Practice for Qualification of Coating Applicators for Application of Coatings to Steel Surfaces

ABSTRACT
This practice provides a qualifying method to verify the proficiency and ability of coating applicators to attain the required quality for application of specified coatings to steel surfaces given the proper tools and equipment. The coating applicator shall be provided with information on the specified coating material and with coating materials properly mixed and ready for application, necessary equipment for application of the specified coating, miscellaneous materials for cleaning the equipment, a practice area, all necessary safety equipment, and thickness gage. The coating applicator shall then be required to demonstrate his ability to apply the specified coating on a test panel using the proper technique and application equipment. The evaluation of the coating applicator shall be made by two qualifying agents, only one of which can be production related. Qualifying agents shall inspect the finished surface and shall verify that it conforms to the requirements specified.
SCOPE
1.1 This practice provides a standard qualifying method for coating applicators to verify their proficiency and ability to attain the required quality for application of specified coatings to steel surfaces including those in safety-related areas in a nuclear facility.  
1.2 Variations or simplifications of the practice set forth herein may be appropriate for special coating work such as maintenance or qualifications of equipment suppliers shop personnel. It is not the intent of this practice to mandate a singular basis for all qualifications.  
1.3 Evaluation of the coating applicator being qualified in accordance with this practice, shall be by qualified agents as specified in 4.1. Reports shall be prepared as specified in Section 5, and certification as specified in Section 6.  
1.4 It is the intent of this practice to judge only the ability of the coating applicator to apply specified coatings with the proper tools and equipment.  
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
