SR EN ISO 12944-9:2018

ISO 12944-9:2018 specifies the performance requirements for protective paint systems for offshore and related structures (i.e. those exposed to the marine atmosphere, as well as those immersed in sea or brackish water). Such structures are exposed to environments of corrosivity category CX (offshore) and immersion category Im4 as defined in ISO 12944-2. ISO 12944-9:2018 describes paint systems for high durability according to ISO 12944-1. ISO 12944-9:2018 is applicable to structures made of carbon steel and does not cover Cd/Bi Cr and Zn/Bi Cr surfaces. It is not applicable to surfaces under insulation or concrete. This document is applicable for paint systems intended for a service temperature range between -20 °C and +80 °C, and the performance testing is aimed at verifying suitability of the paint systems for this temperature range. ISO 12944-9:2018 is applicable for paint systems for submerged service (Im4) which are intended for ambient operating temperatures up to a maximum of 50 °C. ISO 12944-9:2018 specifies: - the test methods to be used to determine the composition o
