What is BS EN 15257?
BS EN 15257 is aimed at enabling the competence of personnel carrying out cathodic protection studies, execution work, inspections and maintenance work to be defined and verified. The relevant application sectors concern underground or immersed metallic structures, marine metallic structures, reinforced concrete structures and the inner surfaces of metallic container structures.
The standard defines the competence levels of personnel within a given application sector and a framework for the training and certification for the personnel to reach and demonstrate the competence levels.
BS EN 15257 defines three competence levels of personnel acting in the field of cathodic protection, including survey, design, installation, testing and maintenance. It specifies a framework of procedures for the training and certification for the personnel to reach and demonstrate the competence levels.
It defines the minimum requirements for certification bodies responsible for this certification. The procedures for certification of cathodic protection personnel should be in accordance with EN ISO/IEC 17024.
Competence levels and certification schemes apply to each of the following application sectors:
• Underground and immersed metallic structures
• Marine metallic structures
• Reinforced concrete structures
• Inner surfaces of metallic container structures.
These application sectors are detailed in BS EN 15257.
It is not mandatory for a certification body to establish certification in all application sectors or to all levels of competence.
Certification Levels
The scheme covers three levels of personnel:
• Level 1 Cathodic Protection Technician
• Level 2 Senior Cathodic Protection Technician
• Level 3 Senior Cathodic Design Engineer
operating in the four industry sections detailed above.
A certification body may subdivide application sectors and may combine levels of competence. If such subdivision and/or combination are used by the certification body, it should ensure that the certificates discriminate these divided sectors or combined levels from those defined in this standard.
BS EN 15257 does not incorporate the certification of companies or services, not does it include internal corporate assessment and qualification of personnel.

Full details of the education, training and experience levels and competences are provided in BS EN 15257.
The level of working knowledge, e.g. awareness, working knowledge or detailed knowledge, of these standards is dependent upon the certification grade as detailed in BSEN 15257.
In addition to this standard, it is also essential that cathodic protection personnel have access to the other BS EN published standards relevant to the application sector. The standards are listed below:
