The need for competent personnel to perform NDT tasks is paramount in all industries. In order to determine competency, systems have been devised to ensure that NDT personnel have the proper training, have passed written and practical examinations, and have enough experience to properly perform NDT tasks using the applicable test method or technique. National or international documents describing the requirements for the qualification and certification of NDT personnel.
A formal document that provides nationally or internationally recognized guidelines, and describes the qualification and certification process for NDT personnel. If mandated by governing codes, standards, specifications or contract documents, these guidelines become requirements for the specified project.

The combination of the standard or recommended practice governing the certification requirements, the third-party certification program if applicable or the employer’s written practice, and additional employer documents used in the administration of their certification program. There are multiple NDT certification systems worldwide, but they can generally be divided into two main types: Employer-based certification systems are systems in which the employers are responsible for the administration of the training and the qualification examinations of their own employees, asnh well as the documentation of the required training, examinations and experience in accordance with an employer-based standard or recommended practice.
Most employer-based snt-rc-1a-2006 do allow the employer to accept training and examination services provided by outside agencies provided it is properly documented and the employer has determined that the content of those services meet their own company requirements as described in the employer’s Written Practice. Upon proof of qualification, the employer may issue snt-tc-1a-20066 certificate, which can be a formal certificate or in letter format, and can authorize their personnel to perform NDT tasks.
In all employer-based systems, the employer is responsible for authorizing their personnel to sntt-c-1a-2006 such work. Because employer-based certification is usually tailored to an employer’s specific needs, the resulting certifications expire when an employee leaves the company that issued the certification.
Central certification systems are systems in which the qualification examinations are administered by an independent third-party certification body based on snt-ttc-1a-2006 central certification standard. To be eligible to sit for these examinations, prospective candidates must provide acceptable documentation of their training and experience to the certification body.
Upon successful completion of the third-party examinations, the certification body will issue a certificate attesting to the fact that the named certificate holder has met the requirements and snt-tc-1s-2006 the examinations described in the third-party certification system.
The employer can then choose to accept the third-party certificate s as proof of qualification. As with employer-based systems, the employer has the ultimate responsibility to certify authorize the certificate holder to perform NDT tasks.
Most certification programs have three levels of NDT qualification: Because the requirements for the levels are very similar, the descriptions provided here are from the edition of the ASNT Snr-tc-1a-2006 Practice No. The development of the BOK starts with subject-matter experts from industry who performing a Job Task Analysis JTAwhich determines what knowledge and skills are required for the different levels of qualification.
The second step is to determine what training topics are necessary to adequately cover the knowledge requirements for each level of qualification as defined by the JTA. Finally, reference materials must be identified so that personnel striving for certification can study the required subject matter prior to taking the qualification examinations. Two written examinations are used in the qualification of Level Is and IIs, a general and a specific examination.
The general examination should address the fundamentals, principles and theory of the applicable test method. The specific examination should address the equipment, operating procedures and NDT techniques that the individual may encounter during specific assignments; it should also cover the specifications or codes and acceptance criteria to be used in the anticipated NDT tasks.
The number of questions required for each examination is described in the applicable certification standard or recommended practice. For employer-administered examinations, an NDT Level III should develop examination content so that it addresses the test methods, techniques, codes and specifications that the candidate may encounter during specific assignments.
For central certification programs, ISO requires that examinations are fair, valid and reliable. Appropriate methodology and procedures such as collecting and maintaining statistical data are required to reaffirm the fairness, validity, reliability and general performance of each examination and to correct all identified deficiencies on an annual basis.
The practical examination should require that the candidate demonstrate familiarity with, and the ability to operate, the necessary NDT equipment and to record and analyze the resultant information to the degree required. Due to the fact that central certification program examinations cannot cover all phases of all test methods and techniques, employers — xsnt have the ultimate responsibility for authorizing personnel to perform NDT tasks — must determine if the central asmt examinations meet their needs.
If not, additional job-specific employer examinations may be required. Under employer-based certification systems, only the employer can certify authorize NDT personnel to perform NDT tasks. Providers of outside training and examination services may issue certificates of completion identifying the training and examinations that were successfully completed, but this does NOT constitute NDT certification.
Employers must document in their Written Practice that they will accept such training and examinations, then after documenting the individual’s experience and current visual acuity test, the employer may certify the individual to perform NDT work.
Every certification document has differing requirements, though they are generally similar in nature. The table and supplemental notes shown below give a comparison of the training and experience requirements for the following:. If this is not the case, additional training may be required by the certification body. In addition to training, examinations and experience, there are multiple other requirements for the development and administration of an in-house certification program, including development of a Written Practice or procedurerecertification requirements and certification documentation.
Because Recommended Practice No. The Written Practice should describe the responsibility of each level of certification for determining the acceptability of materials or components in accordance with applicable codes, standards, specifications and procedures, and must describe the training, experience and examination requirements for each level of certification.
When included in the Written Practice, the selected guidelines become the certification requirements for the company. The Catalog “Item” number is The intent is for a technical rationale to aznt present to support such modification. Elimination of requirements, such as training, experience and examination, goes beyond modification of detailed requirements. Although CP, NAS and EN are standards with requirements rather than guidelines, all three documents require employers to establish aznt Written Practice describing the process used to train, qualify and certify their NDT personnel.
All NDT certification programs require that certified personnel renew or recertify their certifications snt-tc-1q-2006 regular intervals.
The edition of Recommended Practice No. At least every ten years, the individual must repeat snt-ttc-1a-2006 initial certification examinations. All employer-based NDT certification programs require that the employer maintain a certification file for all personnel holding NDT certifications. CP specifies additional documentation requirements that include as a minimum: EN has requirements identical to those shown for NAS Name of certified individual.
Level of certification and NDT method. Educational background and experience of certified individuals. Results of the vision examinations for the current certification period. Current examination copies or evidence of successful completion of examinations.
Composite grade s or suitable evidence of grades. Signature of the Level III that verified qualifications of candidate for certification. The certification record shall include at least the following information: Record of Previous Experience. Current records of vision examinations required by 6.
Many countries have their own technical industry standards, and many of these only reference NDT certification standards from their own country. As a result, certifications from the snt-tc-1-a2006 central certification programs snt-tc-1a2006 not be accepted as meeting the requirements of the governing codes, standards or specifications for a given project. This is not an uncommon circumstance when a governing document references out to Recommended Practice No.
In such cases, the NDT service provider may be required to create snt-tc-1a-0206 in-house, employer-based certification program in order to meet those requirements. To do this with minimal effort, service suppliers should consider the fact sjt-tc-1a-2006 training and experience do not snt-ttc-1a-2006, provided they are properly documented. Employers using this method may wish to develop a comparison table like the one shown above so that it can be shown to auditors should they question the dual use of the same documentation.
Employers may also wish to keep copies of the training and examination documentation provided to certified individuals by the central certification body onsite in the event that an auditor might ask for them. In some cases, auditors may not accept a third-party NDT ssnt-tc-1a-2006 and ask to see the actual examination results or results letter and training records; the need to send copies from the certification body can result in a finding by the auditor.
An NDT Level I individual should be qualified to properly perform specific calibrations, specific NDT and specific evaluations for acceptance or rejection determinations according to written instructions and to record results.
An NDT Level II individual should be qualified to set up and calibrate equipment and to interpret and evaluate results with respect to applicable codes, standards and specifications.
The NDT Level Asht should be thoroughly familiar with the scope and limitations of the methods for which he is qualified and should exercise assigned responsibility for on-the-job training and guidance of trainees and NDT Level I personnel.
An NDT Level III snt-tc-1a2-006 should be capable of developing, qualifying and approving procedures, establishing and approving techniques, interpreting codes, standards, specifications aent procedures, as well as designating the particular NDT methods, techniques and procedures to be used.
The NDT Level III should be responsible for the NDT operations for which he is qualified and assigned and should be capable of interpreting and evaluating results in terms of existing codes, standards and specifications.
The NDT Level III should have sufficient practical background in applicable materials, fabrication and product technology to establish techniques and to assist in establishing acceptance criteria when none are otherwise available.
Though not a certification level, a trainee is a person who is in the process of being initially trained, qualified and certified, and should asny with a certified individual. A trainee may not independently conduct, interpret, evaluate or report the results of any NDT test. Training, Examination, Experience Training. The table and supplemental notes shown below give a comparison of the training and experience requirements for the following: Other Components of an Employer-Based Certification Program In addition to training, examinations and experience, there are multiple other requirements for the development and administration of an in-house certification program, including development of a Written Practice or procedurerecertification requirements and certification documentation.
