Full title and description

ISO 15257:2017 — Cathodic protection — Competence levels of cathodic protection persons — Basis for a certification scheme. This International Standard defines a framework of five competence levels for personnel working in cathodic protection (CP) — covering survey, design, installation, testing, maintenance and the advancement of CP science — and provides the basis for establishing a personnel certification scheme.

Abstract

ISO 15257:2017 specifies the minimum requirements for competence at defined levels and describes application sectors (on‑land metallic structures, marine metallic structures, reinforced concrete structures and inner surfaces of metallic structures containing an electrolyte). The document also provides a certification scheme structure (consistent with ISO/IEC 17024) and normative annexes describing examination, assessment, certificate formats, validity and re‑certification arrangements.

Scope

ISO 15257:2017 defines five competence levels for persons performing cathodic protection activities and sets out the minimum knowledge, skills and attributes associated with each level. The standard applies across multiple application sectors — on‑land metallic structures, marine metallic structures, reinforced concrete structures and the inner surfaces of metallic structures that contain an electrolyte — and provides the structure and requirements for a personnel certification scheme consistent with ISO/IEC 17024. It is intended to be used by certification bodies, employers, training organisations and national bodies to harmonise competence criteria and certification practices.

Key topics and requirements

• Definition of five CP competence levels and associated job‑task analysis used to derive required knowledge and skills.
• Application sectors: on‑land metallic, marine metallic, reinforced concrete, and inner surfaces of metallic structures containing electrolytes.
• Framework and minimum requirements for establishing a personnel certification scheme (alignment with ISO/IEC 17024).
• Normative annexes describing certification scheme elements: examination/assessment procedures, certificate format, validity periods, re‑certification and transition arrangements.
• Guidance to implement job‑task analysis (JTA) outputs into training, assessment and competency records for CP personnel.

Typical use and users

Primary users include cathodic protection engineers and technicians, training providers, certification bodies, asset owners/operators (pipelines, offshore and onshore structures, reinforced concrete infrastructure), inspection and maintenance organisations, and national standards/qualification bodies who require harmonised competence criteria for personnel certification and workforce qualification. Employers and accreditation bodies use the standard to design certification schemes and assessment processes.

Related standards

ISO 15257 is part of the broader family of standards addressing cathodic protection and corrosion control. Key related documents include ISO/IEC 17024 (requirements for bodies operating certification of persons), ISO 12696 (cathodic protection of steel in concrete), ISO 12473 (principles of CP in seawater) and application standards such as ISO 15589 (pipeline CP), EN/ISO application‑specific documents (EN 12954, EN 12495, EN 12496) and other ISO/TC 156 publications covering CP and corrosion of metals. These documents are commonly used together when specifying CP design, selection, testing and personnel certification.

FAQ

Q: What is this standard?

A: ISO 15257:2017 specifies competence levels for persons working in cathodic protection and provides a basis for establishing a personnel certification scheme.

Q: What does it cover?

A: It covers five defined competence levels, minimum requirements for knowledge, skills and attributes, applicable CP application sectors (on‑land metallic, marine metallic, reinforced concrete and inner surfaces containing electrolyte) and a certification scheme structure including examination, certification and re‑certification arrangements.

Q: Who typically uses it?

A: Certification bodies, CP engineers and technicians, training organisations, infrastructure owners/operators, inspection/maintenance contractors and national standards or accreditation bodies that develop or operate personnel certification schemes for cathodic protection.

Q: Is it current or superseded?

A: The ISO record shows ISO 15257:2017 as the first edition published in May 2017; the document was reviewed and confirmed in 2022 and remains current according to ISO’s lifecycle record. Users should check national adoptions or amendments for any regional implementation details.

Q: Is it part of a series?

A: It belongs functionally to the suite of ISO/TC 156 standards on corrosion of metals and allied products and to the family of CP application standards (for example ISO 12696, ISO 12473, ISO 15589 and various EN standards). It is also intended to be used in conjunction with ISO/IEC 17024 when creating personnel certification schemes.

Q: What are the key keywords?

A: cathodic protection, competence levels, personnel certification, certification scheme, corrosion, reinforced concrete, marine CP, pipeline CP, ISO 15257, ISO/IEC 17024.
