Revised in 2018! This NACE International/SSPC joint standard practice covers the preparation of concrete surfaces before the application of protective coating or lining systems. The standard includes two updated tables, Table 1 details classes of surface preparation, and Table 2 provides minimum acceptance criteria for concrete surfaces before coatings are applied and relevant test methods. The updated Appendix (nonmandatory) includes two additional tables, Table A1 provides typical surface properties of finished concrete, and Table A2 provides an extensive list of surface preparation methods for concrete surfaces. This standard should be used by specifiers, applicators, inspectors, and others who are responsible for defining a standard degree of cleanliness, strength, profile, and dryness of prepared concrete surfaces.
This updated NACE International standard test method specifies test methods to evaluate the performance of liquid coating systems for seawater immersion services. This test method is intended for use by facility owners and coating manufacturers.The test method covers liquid exterior protective coating systems for offshore platform steel structures, piers, docks, pilings, subsea valves, and wellheads at normal seawater temperature.
Included are four test methods—including cathodic disbondment, seawater immersion resistance, aging stability, and edge coverage—used to evaluate coating systems. The test method also includes two tables; Table 1 details fingerprinting of coating materials, and Table 2 details the test panel geometry, size, substrate material, and minimum quantity.
