1.1This guide is intended as an information aid to painting inspectors in carrying out their task efficiently. It includes the key elements of surface preparation, coatings application, and final approval for both field and shop work. The items should be selected that are pertinent to the specification of a particular job.
Note 1:For additional helpful information, refer to the following documents: Manual of Coating Work for Light-Water Nuclear Power Plant Primary Containment and Other Safety-Related Facilities 2 New Concepts for Coating Protection of Steel Structures3 D16 Terminology for Paint, Related Coatings, Materials, and Applications 4 D4538 Terminology Relating to Protective Coatings and Lining Work for Power Generation Facilities 4 Steel Structures Painting Manual Vol 1 Good Painting Practice 6 Steel Structures Painting Manual Vol 2 Systems and Specifications 6 Manufacturers Specifications and Instructions (made available to the inspector for reference to special requirements for proper application) Safety Data Sheets (needed to ensure that personnel take necessary precautions in handling hazardous materials). Available from Materials manufacturer.
1.2Certain industries or owners may require certified inspection personnel. See Guide D4537 for establishing procedures to certify inspectors for coatings work in nuclear facilities.
1.3The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4This 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.
