Much of the data on chemical resistance of commercially available coating materials is inadequate, incomplete, and difficult to interpret. This standard was prepared to help manufacturers and users of protective coatings and linings in their selection of materials by providing standard test methods for the evaluation of protective coatings and linings for immersion service.

In issuing this standard, it has been recognized that many of the steps involved in the application of materials can be classified as an "art." Therefore, samples for testing should be prepared in a manner to approximate field conditions as closely as possible.

Small panels, whether laboratory or plant tested, may give results that are not necessarily indicative of performance when the same coatings are applied to process equipment. This standard provides two test methods for evaluating protective coatings on any substrate, such as steel, copper, aluminum, etc., so that both the factors of chemical resistance and permeability can be considered. The results obtained should give a good indication of what would happen on exposure to similar service conditions.

Protective coatings, as referred to in this standard, can be applied in liquid form (solution, dispersion, etc.) or dry form (powders), using spray, dip, roller, brush, trowel, or other appropriate application techniques. These coatings may contain fillers or reinforcement, such as glass cloth or flakes, silica, mica, etc.

This standard is issued by NACE International under the auspices of NACE Group Committee T-6 on Protective Coatings and Linings. The standard was originally prepared in 1974 by Task Group T-6A-23, a component of Unit Committee T-6A on Coating and Lining Materials for Immersion Service. The standard was reaffirmed with editorial revisions by Unit Committee T-6A in 1991 and 1996.

1.1 This standard provides two test methods for evaluating the performance of protective coatings and linings used as lining materials in immersion service: one-side testing of the panel and immersion testing of the panel. Protective coatings and linings will be referred to as coatings in this standard.
