HISTORICAL DOCUMENT. The purpose of this NACE International test method is to standardize the testing methods and conditions used to determine acceptable temperature limits for personnel protection for insulative coatings in accordance with ASTM C1055. The temperature limits determined when using this test method are specific for each coating tested at a particular thickness and substrate temperature. A standardized test method can validate the temperature limits of a coating used for personnel protection, and enable direct comparison of its performance. This test method is intended for use by facility owners, engineers, health and safety specialists, coatings manufacturers, and other interested parties.
HISTORICAL DOCUMENT. Defines the Thorough Cleaning (WJ-3) degree of surface cleanliness - one of four levels (WJ- 1,2,3,4) achieved by the use of waterjet cleaning.

HISTORICAL DOCUMENT. Defines the Light Cleaning (WJ-4) degree of surface cleanliness - one of four levels (WJ- 1,2,3,4) achieved by the use of waterjet cleaning.
HISTORICAL DOCUMENT. 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.
