Element offers testing to international standards ISO 12944-6 and ISO 12944-9 (formerly ISO 20340) to aid in the selection of suitable paint systems for corrosion protection of steel structures.

When steel is left unprotected in the environment, whether that be atmospheric or immersed in soil or water, it is subject to corrosion that can lead to damage to infrastructure. Protective coating systems are normally deployed to avoid this damage. ISO 12944 looks at these protective coating systems and provides test criteria that demonstrate the suitability of a protective coating of different environmental corrosivity categories including the new CX and Im4 categories. 

As a global ISO 17025 certified laboratory, Element carries out testing to the highest quality and latest industry standards to ensure coating schemes are fit-for-purpose.

Element’s corrosion testing experts help support you in this new version of the standard. They can explain the differences between the 1998 version and the current 2018 update, ensuring the most appropriate testing is undertaken to approve your protective coating system. 

Customized testing to ISO 12944

In addition to ISO 12944 testing, Element can support you in our state-of-the-art testing facility with a customized test program to measure the effectiveness of protective coatings systems and provide you with the most accurate information to meet your specific project needs.
