The PCN scheme provides an independent central certification scheme embodying modern quality assurance requirements and a commitment to conform with European and international standards. The PCN scheme is owned and managed by the British Institute of NDT (BINDT).
Certificates are issued following success in a thoroughly searching examination conducted at BINDT Authorised Qualifying Bodies, and are valid for five years. After the first five year period of validity, certificates may be renewed following the submission of evidence of continuous satisfactory employment in the application of NDT. At the end of a second five year period of validity, recertification follows success in an examination which, in the case of Levels 1 and 2, consists of a practical test or, in the case of Level 3, a written test or compliance with a structured credit system.
PCN certificates satisfy the requirements of European Standard EN 473 and international standard ISO 9712. The qualification requirements of PCN (eyesight, training and experience) also satisfy the provisions of a number of other widely accepted national and international standards and guidelines.
Candidates who are successful in the qualification examination, but who have not yet acquired the experience necessary for certification should, when experience has been gained under appropriate certified supervision ( see PCN/GEN for detail information ), apply for PCN certification directly to the certification services division of the British Institute of NDT with evidence of the requisite experience.
Employers may find it convenient to utilise the PCN system within their internal NDT personnel certification programs (e.g., within SNT-TC-1A or EN4179 systems). Further guidance on any aspect of NDT personnel certification may be obtained from BINDT certification services at Northampton.
An individual certificated to Level 1 is qualified to carry out NDT operations according to a written instruction and under the supervision of Level 2 or Level 3 personnel. PCN Level 1 certificated personnel have demonstrated the competence to set up equipment, carry out the test, record and classify the results in terms of written criteria, and to report the results. Level 1 personnel have not demonstrated competence in the choice of test method or technique to be used, nor for the assessment characterisation or interpretation of test results.
This Level 2 is qualified to perform and direct NDT according to established or recognised procedures and have demonstrated competence to choose the technique for the test method used; setup and calibrate equipment; perform and supervise the test; interpret and evaluate results according to applicable standards, codes or specifications; define the limitations of application of the testing method for which they are qualified; understand and transform NDT standards and specifications into practical testing instructions adapted to actual working conditions; prepare written test instructions; carry out and supervise all Level 1 duties; organise and report the results of Non-Destructive Tests.
Personnel holding this, the highest Level, or qualified to direct any NDT operation for which they are certificated and : assume full responsibility for a test facility and staff; established and/or validate NDT instructions or procedures; interpret, standards, specifications and procedures; designate the particular test methods, techniques and procedures to be used. Level 3 personnel have demonstrated: a competence to interpret and evaluate test results in terms of existing codes, standards and specifications; possession of the required level of knowledge in applicable materials, fabrication and product technology sufficient to enable the selection of methods and techniques, and to assist in the establishment of test criteria where none are otherwise available; familiarity with other NDT methods; the ability to guide personnel below Level 3. Where Level 3 duties regularly require the individual to apply routine NDT by a method or methods, BINDT recommends that industry demand that is person should hold and maintain Level 2 certification in those methods.
