Standard Practice for Qualification of Coating Applicators for Application of Coatings to Concrete Surfaces
ABSTRACT
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 concrete surfaces including those in safety-related areas in a nuclear facility. Variations or simplifications of the practice may be appropriate for special coating work such as maintenance. This practice does not intend to mandate a singular basis for all qualifications. It intends to judge only the ability of the coating applicator to apply specified coatings with the proper tools and equipment. This practice requires the coating applicator perform the application using the proper technique and application equipment. The surfaces of the concrete test area shall be prepared as prescribed. The coating applicator shall demonstrate the ability to apply the specified coating to the prescribed uniform dry film thickness Evaluation of the coating application, reports preparation, and qualifications shall conform to this practice.
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 concrete 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. 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 qualification 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 and health practices and determine the applicability of regulatory limitations prior to use.
