NACE TM21423-2023

The purpose of this AMPP test method is to standardize the testing methods and conditions used to determine the substrate and surface temperature limits for different thicknesses of insulative coatings used for personnel protection to be in compliance 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 to other commercially available coatings. This test method is intended for use by facility owners, engineers, health and safety specialists, coatings manufacturers, and other interested parties.
