19、mmittee CEN/TC 219 “Cathodic protection”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2007, and conflicting national standards shall be withdrawn
20、at the latest by June 2007. This document 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, mari
21、ne metallic structures, reinforced concrete structures and the inner surfaces of metallic container structures. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus,
22、Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 15257:2006 (E) 5 1 Scope This European Sta
23、ndard defines three competence levels (Annex B) 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 competenc
24、e 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 appli
25、cation sectors: underground and immersed metallic structures; marine metallic structures; reinforced concrete structures; inner surfaces of metallic container structures. These application sectors are detailed in Annex A. It is not mandatory for a certification body to establish certification in all
26、 application sectors or to all levels of competence. 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 co
27、mbined levels from those defined in this standard. NOTE 1 This European Standard does not incorporate the certification of companies or services. NOTE 2 This European Standard does not include internal corporate assessment and qualification of personnel. NOTE 3 Wherever gender specific words such as
28、 “his“, “her“, “he“ or “she“ appears in this standard the other gender is also applicable. 2 Normative references The following referenced documents are indispensable for the application of this document.
