标准范围

This document describes various corrosion under insulation (CUI) environments in refineries and 
other related industries and environments, and establishes CUI environmental categories including 
operating temperature ranges from −45 °C to 204 °C for topside and aboveground service only. This 
document specifies both established and other test methods for the assessment of coatings used for 
prevention of CUI for each given environment. This document also provides acceptance criteria for each 
CUI environment.
NOTE The test results and acceptance criteria can be considered an aid in the selection of suitable coating 
systems. For service or peak temperatures below −45 °C an optional cryogenic test can be incorporated and for 
over 204 °C testing acceptance criteria can be agreed between interested parties. Additional or other test and 
acceptance measures are possible, but require particular agreement between the interested parties.
This document covers spray-applied coatings applied on new carbon and austenitic stainless steel for 
use in CUI service. This document does not cover testing of sacrificial coatings, such as inorganic zinc, as 
these coatings can be consumed quickly in wet environments. Developing accelerated corrosion testing 
for what can be continuous wet service with sacrificial coatings is beyond the scope of this document.
“Non-through porosity” thermal spray aluminium coatings with greater than 250 µm dry film thickness 
can be tested and qualified in accordance with this document. This document does not cover tape and 
sheet applied products for use in preventing CUI.
This document does not deal with other aspects of coating degradation, such as those caused by 
abrasion, erosion, ultraviolet degradation or other methods that can exist given specific environment 
and construction methods.
