What are the goals in NDT Proficiency Testing?

There are some typical goals for labs of Interlaboratory comparisons as follows:
  • Performance assessment in quality of proceedings of NDT services; its quality comparisons
  • Contributions to improvements of quality level of services in which each participant has been active
  • Continuous improvements in management practises in NDT labs
  • Contributions to building a trust and recognition of the customers for quality of each lab
  • Compliance with accreditation requirements
The need for permanent confidence in the performance of each NDT lab is not only essential factor for labs, customers and regulation bodies, but also for the accreditation and authorization organisations. Additionally, there is a growing demand for Proficiency testing for other activities of conformity assessment such as inspection and certification of the products.

ATG compliance as an NDT proficiency testing provider

Based on the compliance with EN ISO/IEC 17043 requirements, ATG s.r.o. had been awarded an accreditation of the Czech Accreditation Institute in 2013 under the title “Proficiency Testing Provider ATG” (PTP ATG) and Valid certificate of accreditation.

In April 27, 2017, “Agreement of Mutual Recognition of Accredited Conformity Assessment Results EA MLA” for Proficiency testing according to EN ISO/IEC 17043 had been signed. This means that a test report or certificate issued by accredited body by an EA MLA signatory (such as ATG s.r.o.) is also recognized by the signatories to the IAF and ILAC multilateral agreements. Because of this, there is no need for these services to be re-tested, re-calibrated, re-inspected or re-certified in any other country.
Within granted accreditation of ATG, this EA MLA agreement has been applied for the area of Proficiency testing for NDT labs in MT, PT, RT, UT, VT, ET and LT methods.
