As a generic descriptions of a coating material does not always ensure that all will perform in the same harsh CUI service, testing and acceptance criteria will help owners to ensure that specific coating materials, however described, can provide service as required in industrial CUI environments. The intent of these test procedures is not meant to rank coatings, but as an acceptance testing methodology. Owners of refining and petrochemical facilities can have product approval lists developed using the testing an acceptance criteria for product inclusion on specifications.
This paper will present a potential international methodology for testing and acceptance of coatings for insulated service. Initially four (4), both continuous and cyclic service thermal conditions over a wide range of temperature, mostly as developed with in NACE SP0198 will be described in CUI classifications....
