NACE TM 21423:2017

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.
