abstraction

This practice provides a qualified method for verifying the proficiency and ability of the coating applicator to achieve the quality required to apply a specific coating to the steel surface, given the appropriate tools and equipment. The coating applicator should provide information about the specified coating material, the coating material should be properly mixed and ready for painting, the equipment needed to paint the specified coating, miscellaneous materials for cleaning the equipment, the operating area, all necessary safety equipment, and a thickness meter. The paint applicator is then asked to demonstrate its ability to apply the specified coating to the test plate using the appropriate technology and application equipment. Evaluation of coating applicators should be carried out by two qualified agents, only one of which can be related to production. The qualified agent shall inspect the finished surface and verify that it complies with the specified requirements.

Radius

1.1 This practice provides a standard qualification method for paint coaters to verify their proficiency and ability to apply specific coatings to steel surfaces, including areas relevant to safety at nuclear facilities.

1.2 Variations or simplifications of practices described herein may apply to special coating work, such as maintenance or qualification of equipment supplier workshop personnel. The purpose of this approach is not to mandate a single basis for all qualifications.

1.3 Evaluation of coating applicators in accordance with this practice shall be carried out by the qualified agent specified in 4.1. Reports shall be prepared in accordance with Section 5 and certified in accordance with Section 6.

1.4 The purpose of this practice is to judge only the ability of a paint applicator to apply a particular paint using appropriate tools and equipment.

1.5 Values in inch-pounds shall be considered standard. The values given in parentheses are for reference only.

1.6 This standard is not intended to address all safety concerns (if any) associated with its use. It is the responsibility of users of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
