Cathodic protection - Competence levels of cathodic protection persons - Basis for certification scheme (ISO 15257:2017)

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.

Protection cathodique - Niveaux de compétence des personnes en protection cathodique - Base pour un dispositif particulier de certification (ISO 15257:2017)

ISO 15257:2017 définit cinq niveaux de compétence (détaillés à l'Article 4) pour les personnes travaillant dans le domaine de la protection cathodique (PC), incluant l'étude préalable, la conception, l'installation, le contrôle, la maintenance, ainsi que les progrès scientifiques en protection cathodique. Il spécifie un cadre pour l'établissement de ces niveaux de compétence, ainsi que les exigences minimales correspondantes.
Les niveaux de compétence s'appliquent à chacun des secteurs d'application suivants:
- les structures métalliques terrestres;
- les structures métalliques en mer;
- les structures en béton armé;
- les surfaces intérieures des structures métalliques contenant un électrolyte.
Ces secteurs d'application sont décrits en détail à l'Article 5.
ISO 15257:2017 spécifie les exigences à utiliser pour établir un dispositif particulier de certification comme défini dans l'ISO/IEC 17024. Il n'est pas obligatoire d'appliquer tous les niveaux et/ou tous les secteurs d'application. Ce dispositif particulier de certification est décrit en détail dans les Annexes A, B et C.

Katodna zaščita - Stopnje usposobljenosti in certifikacija osebja za katodno zaščito - Osnova za shemo certificiranja (ISO 15257:2017)

Ta mednarodni standard določa pet stopenj usposobljenosti in certificiranja osebja, ki deluje na področju katodne zaščite, vključno s pregledom, projektiranjem, namestitvijo, preskušanjem in vzdrževanjem. Določa okvir za vzpostavitev teh stopenj usposobljenosti in certificiranja ter minimalne zahteve. Stopnje usposobljenosti in certificiranja se uporabljajo v vsakem od naslednjih sektorjev: – kovinske strukture na kopnem; – pomorske kovinske strukture; – strukture iz armiranega betona; – notranje površine iz kovinskih oklopnih struktur. Ta mednarodni standard določa zahteve, ki se uporabljajo za vzpostavljanje sheme certificiranja, kot določa standard ISO/IEC 17024. Ta shema certificiranja je podrobno opisana v dodatkih A, B in C. Informacije: Tehnični odbor CEN/TC 219 je razvil standard EN 15257:2006, ki ga sedaj sprejema tehnični odbor ISO/TC 156 z nekaterimi spremembami izvirnega dokumenta EN. Tehnični odbor ISO/TC 156 je registriral delovni element ISO kot delovni element ISO v skladu z dunajskim sporazumom, vendar ga tehnični odbor CEN/TC 219 ni odobril kot aktivni delovni element CEN/TC 219 v skladu z dunajskim sporazumom, kar je potrebno za vzporedno aktivno glasovanje tehničnega odbora CEN/TC 219. Tehnični odbor CEN/TC 219 je odobril NWIP kot delovni element ISO v skladu z dunajskim sporazumom.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

Introduction

This document enables the competence of cathodic protection (CP) persons carrying out cathodic

protection survey, design, installation, testing and maintenance work to be defined and verified.

The relevant application sectors concern on-land metallic structures, marine metallic structures,

reinforced concrete structures and the inner surfaces of metallic structures containing an electrolyte.

Demonstration of competence is possible by certification. This document offers a certification scheme

in accordance with ISO/IEC 17024.

In preparation of Clauses 4, 5 and 6, a detailed job task analysis (JTA) was undertaken by consensus

of the experts in ISO TC 156. This JTA was then subject to review by international experts during

the ISO enquiry process. It is considered that Clauses 4, 5 and 6 constitute a rigorous JTA. The JTA is

largely based on similar work performed by CEN/TC 219, which produced EN 15257, which has been in

widespread use since 2007.
