scope:

This International Standard defines five levels of competence for persons acting in the field of cathodic protection, including survey, design, installation, testing and maintenance. It specifies a framework for establishing these competence levels and their minimum requirements. Competence levels apply to each of the following application sectors: - on-land metallic structures; - marine metallic structures; - reinforced concrete structures; - inner surfaces of metallic container structures. This International Standard defines the requirements to be used for establishing a certification scheme as defined in ISO/IEC 17024. This certification scheme is detailed in normative Annexes A, B and C. Info: CEN/TC 219 developed EN 15257:2006 which is now being adopted by ISO/TC 156 with some changes from the original EN document. The ISO Work Item was registered by ISO/TC 156 as ISO lead Vienna Agreement Work Item but was not approved within CEN/TC 219 as an active CEN/TC 219 Work Item under ISO lead Vienna Agreement which is required for CEN/TC 219 to actively vote in parallel. CEN/TC 219 approved the NWIP as an ISO lead Vienna Agreement Parallel Work Item.
