Certification of Personnel Involved in Non-Destructive Testing

Non-Destructive Testing comprises a set of examinations, checks, and surveys conducted using methods that do not alter the material and do not require the destruction or removal of specimens from the structure under examination. The fundamental characteristic of this type of testing is its ability to verify details without interfering with the material.

Certification Process

The certification process for personnel engaged in non-destructive testing involves the following steps:

1. Acceptance of the economic offer.

2. Submission of the certification application.

3. Performance of qualification tests according to the required standards.

4. Deliberation and issuance of certification.

To be admitted to the qualification exam, personnel engaged in non-destructive testing must have the required training (training course), industrial experience in NDT, and visual acuity, as specified by the reference standard. Additionally, they must undergo a qualification exam for each testing method they intend to qualify for.

The exam for levels I and II consists of three phases:

1. General theoretical exam

2. Specific theoretical exam

3. Practical exam

The general and specific exams consist of a defined number of multiple-choice questions based on the chosen testing method.

The practical exam involves conducting tests on examination samples with predefined defects, recording, interpreting, and documenting the obtained results.

For qualification at level II according to ISO 9712, the drafting of a work instruction for level I is required.
