Element offers testing of protective coatings to Norsok M501 for offshore installations and associated facilities to help companies select the coating systems which provide optimum protection with minimum maintenance, easy application, and fully documented HS&E impact evaluations.


As an ISO 17025 approved laboratory, Element carries out testing to the highest quality standards. Our coatings experts will support you throughout the whole Norsok M501 testing program.


To deliver consistent and accurate results Element offers 3rd party witnessing of the paint applications as part of the Norsok M501 approval process. This includes pre-application checks (such as surface profile, cleanliness and salt contamination) and recording of all necessary information during the application, including air temperature, steel temperature, humidity, dew point, tip sizes, spray pressure and batch numbers.
