Significance and Use

3.1?This guide is intended as a reference for those concerned with the inspection of industrial coating work. The requirements for inspection should be addressed in all protective coating and lining work specifications. This guide may be used by specification writers when selecting and establishing the inspection requirements for coating and lining specifications. A checklist for use by inspectors in the field is included in Appendix X1.

1. Scope

1.1?This 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 1.2?Certain industries or owners may require certified inspection personnel. See Guide D4537 for establishing procedures to certify inspectors for coatings work in nuclear facilities.

1.3?The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4?This guide is arranged in the following order:
