Standard: EN 12068 Cathodic protection – External organic coatings for buried or immersed steel structures used in pipeline applications – including Indentation Resistance

EN 12068 specifies requirements for external organic coatings applied to buried or immersed steel structures, primarily pipelines, for use in conjunction with cathodic protection. These coatings play a critical role in providing passive corrosion protection and work synergistically with cathodic protection systems to ensure the long-term integrity and safety of pipelines in aggressive environments.

The standard outlines comprehensive performance criteria for these coatings. A key aspect of this standard is its detailed assessment of the coating’s resistance to mechanical damage, which explicitly includes tests for impact resistance. These impact tests simulate the types of forces the coating might encounter during pipeline installation, backfilling, or from external factors during its operational life. Ensuring the coating can withstand impacts without compromising its protective barrier is essential for maintaining the effectiveness of the corrosion prevention system and the overall integrity of the pipeline.
