Non Destructive Testing

Non-destructive testing (NDT) is the descriptive term used for the examination of materials and components in a way which does not change or destroy their usefulness. NDT plays an important role in assuring that structural and mechanical components perform their function in safe, reliable, and cost-effective operations, with resultant benefit to the community.

NDT allows for careful and thorough materials evaluation without the need for destructive or damage. NDT is typically used at various points in our part’s life cycle. NDT can be used prior to the use of a component for the sake of quality control. NDT is also employed while components are in use to detect service related conditions caused by wear, fatigue, corrosion, stress or other factors which affect reliability.

Non-destructive testing is reliable only when undertaken to appropriate standards. To ensure this a wide range of national and international standards are documented which covers specific industry needs.


NDT Training & Certification

ISO 9712 Certification Scheme

This International standard specifies requirements for principles for the qualification and certification of personnel who perform industrial non-destructive testing (NDT).

The system specified in this International standard is applicable to other NDT methods or to new techniques within an established NDT method, provided a comprehensive scheme of certification exists and the method or technique is covered by International, regional or national standards or the new NDT method or technique has been demonstrated to be effective to the satisfaction of the certification body.

ASNT NDT Certification Systems

There are multiple NDT certification systems worldwide, but they can generally be divided into two main types: “employer-based” and “central” certification systems.

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, as well as the documentation of the required training, examinations and experience in accordance with an employer-based standard or recommended practice. Most employer-based systems 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.

Central certification systems are systems in which the qualification examinations are administered by an independent third-party certification body based on a 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 passed 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.
