also known as non-destructive examination (NDE), non-destructive
inspection (NDI) and non-destructive evaluation (NDE). Comprising, but
not limited to the following methods and techniques: MT, PT, RT, RT-D,
VT, UT, PAUT, TOFD, and ET and/or ACFM

ANDT

The above definition of NDT applies, however ANDT includes advanced
methods such as RT-D, PAUT, TOFD and AUT.

The supervisors' and operators' certificates and competence shall comprise all industrial andproduct sectors and techniques being applied by the NDT Service Supplier.

(cont)
Level 3 personnel shall be certified by an accredited certification body.
Level 3 personnel shall be certified by one of the following means:(i) obtain certification from an accredited certification body.
(ii) obtain certification from an employer based scheme via the examination method, as
detailed in the written practice. It is not permissible to directly appoint a level 3 without

The Supplier shall have a supervisor or supervisors, responsible for the appropriate execution
of NDT operations and for the professional standard of the operators and their equipment,
including the professional administration of the working procedures. The Supplier shall
employ, on a full-time basis, at least one supervisor independently certified to Level 3 in themethod(s) concerned as per the requirements of item 2.3. It is not permissible to appoint
Level 3 personnel; they must be certified by an accredited certification body. It is recognisedthat a Supplier may not directly employ a Level 3 in all the stated methods practiced. In suchcases, it is permissible to employ an external, independently certified, Level 3 who is certified
by an accredited certification body in those methods not held by the full-time Level 3(s) of the
Supplier.
The supervisor shall be directly involved in review and acceptance of NDT Procedures, NDTreports, calibration of NDT equipment and tools. The supervisor shall on behalf of the
Supplier re-evaluate the qualification of the operators annually.
The NDT Service Supplier shall have a supervisor or supervisors, responsible for thefollowing:a) validate NDT instructions and procedures established and reviewed by level 3 personnel;b) review of NDT reporting;c) supervise all tasks and NDT operations at all levels;d) inspection of NDT equipment, tools and calibration;e) re-evaluate the qualification of the operators annually on behalf of the NDT Service
Supplier.
Normally, the NDT Service Supplier shall employ (on a full-time basis) a level 3 supervisor,
certified to level 3 in the applicable method(s) as per the requirements of this UR.
It is recognised that an NDT Service Supplier may not directly employ a Level 3 in all thestated methods practiced.
