Levels of certificates
Persons who perform nod-destructive testing in industrial area can be certificated on three different levels: Level I – using the specified manual the person notes discovered indications and classifies them. Level II – besides the knowledge for level I, the person must know how to make written manual for NDT, chose the testing technology and to evaluate testing results using the standards and regulations. Level III – person takes full responsibility for testing, equipment and personnel, designs work procedures and introduces various techniques, validates the procedures and trains NDT human resources.
Sectors of products and industrial sectors
Certification of NDT personnel in accordance to EN ISO 9712 is possible for the following sectors of products: Castings C, Forgings F, Welds W, Tubes T, Transformed products WP, Industrial sectors: Production – A testing before and during exploitation and production – B testing of pressure equipment in accordance to 97/23 EC – PED
Directive about pressure equipment
In annex I, article 3.1.3. directive 97/23/EC is stated that personnel that test pressure equipment must be certified in accordance to EN ISO 9712. Named body for pressure equipment then gives the authority the person to inspect pressure equipment. The Welding Institute has been named for notified body for EU for the area of pressure equipment under serial number 2042. Personnel that wishes to get certification for the area of PED needs to have besides of the above requirements, minimum of 60 days of working experience on pressure equipment in the last 12 months. Working experience is conformed from the employer, company that makes pressure equipment or named body. Personnel for the area of PED needs to successfully complete additional qualification (exam).
Necessary working experience
In the next table are given data according to EN ISO 9712 about experience in months that candidate for certification has to have prior to acquiring certificate.
| NDT Method | Level 1 | Level 2 | Level 1+2 | Level 3 |
|---|---|---|---|---|
| MT,PT,VT | 1 | 3 | 4 | 12 |
| UT,RT,LT | 3 | 9 | 12 | 18 |
Minimum of necessary training
The next table shows minimal number of hours that candidate for certification needs to attend in an authorized center for NDT before he can access the qualification exams.
| Minimum of education | Level 1 | Level 2 | Level 3 | |
|---|---|---|---|---|
| MT,PT,VT | 16 | 24 | 32,24,24 | |
| UT,RT | 40 | 80 | 40 | |
| LT | B- process with measuring pressure | 24 | 32 | 32 |
| LT | C- process with gas monitoring | 24 | 40 | 40 |
For submethod UTT is minimum education of 24 hours, for RT.FAS is 56 hours.
Qualification exam
It is consisted of two parts, theoretical and practical part. Theoretical part is consisted of two tests:
- General
- Specific
The certificate validity
After candidate fulfills all the requirements for certification, he gets the certificate. Certificate is valid only of candidate has a valid certificate on the appropriate vision. Besides that, candidate has to have written authorization from the employer for performing examination using the certified method. Revalidation of certificate is done for the first time after 5 years of the first certification. Candidate must submit the written request for revalidation. A precondition for the extension is that the candidate didn’t have longer periods of termination in use of the certificate (one continued termination longer the a year, or more of the shorter termination, that together are longer that two years). The candidate delivers a certificate of continuous working conformed from the employer and the certificate of vision. Certificate of vision has to be renewed every year. Application for revalidation of certificate candidate can submit within the last 6 months of the certificate validity. In emergency cases, this application can be submitted no later than 12 months after the validity of certificate expires. For this kind of application, the candidate has to have a valid reason and it needs to be in written form with documented evidence (say in case of sickness). These kind of application evaluates a special commission of the certification body VARcert. In case that the candidate is late to all the deadlines for certificate revalidation, he has to retake the first certification. Revalidated certificate is valid for the next 5 years. Recertification (revalidation of the certificate) is performed after the second five year period has expired, i.e 10 years after the first certification. A precondition is that the certification has been renewed after the first 5 years. Conditions for recertification are similar to the conditions for revalidation, only that the candidate has to partake in the practical part of the exam.
