You’ve been a Level
2 for over 5 years; you’re getting a bit fed up with all the
travelling around and you are ready for another challenge.
Typically these are the considerations usually put
forward for those NDT operators looking to move up to Level 3 – there
are others of course – your Company needs you to; maybe there
is more money or more responsibility on offer. But whatever the reason
there are
still plenty of candidates for the Level 3 exams.
First Things First
Let’s however start off with a review of exactly
what a Level 3 is and what he/she can do and of course what exams
are needed.
There are two types of Level 3 programme available – the eligibility
requirements are pretty much the same and the best route in my opinion
is work experience at the Level 2 in your chosen method of around 6
years. Alternative eligibility parameters come into play depending
on your level of relevant education but we recommend that your best
starting point is good practical work experience in a variety of NDT
methods over a number of years.
The first type of Level 3 programme is provided by the Central Certification
Programmes – EN4731 (PCN2), ISO 97123 (PCN) and the ASNT Level
3 Certification programme; then secondly are the Employer-based Certification
Programmes essentially all based around SNT-TC-1A4, which have their
own specific requirements but must all be documented within the Company
Written Practice.
A Level 3 within an employer based programme can only
be a Level 3 for that Company within the limits of their Quality
System requirements reflected in the Written Practice.

Examples of employer based programmes
requiring a Written Practice for the Training, Examination and Qualification
of NDT personnel are EN41795, NAS 4106, RPS 9087 (Rolls Royce), Boeing8
and BAE Systems9. There are of course as many Company Level 3 programmes
as there are Employers.
What is the Role?
The role of the Level 3 in NDT is a highly responsible one – it
is only necessary to look at the level of qualification as defined
in SNT-TC-1A (2001) to appreciate this. The NDT Level 3 should:
- be capable of developing, qualifying and approving procedures,
establishing and approving techniques, interpreting codes, standards,
specifications
and procedures; and designating the particular NDT methods, techniques
and procedures to be used;
- be responsible for the NDT operations for which qualified and assigned
and should be capable of interpreting and evaluating results
in terms of existing codes, standards and specifications;
- have sufficient practical background in applicable materials, fabrication
and product technology to establish techniques and to assist
in establishing acceptance criteria when none were otherwise
available;
- have general familiarity with other appropriate NDT methods as
demonstrated by an ASNT Level 3 Basic examination or other means;
- be capable of training and examining NDT Level 1 and 2 personnel
for certification in those methods in which certified.
The responsibilities are much the same within the PCN Level 3 system.

Central Certification
ASNT NDT L3 examinations are fairly straightforward to explain:
You must pass the Basic ASNT Examination and
you must pass a Method Examination.
PCN Level 3 requires that:
You must pass the Basic PCN Examination and you must
pass a Method Examination, plus for PCN you must hold the relevant
Level 2 Certificate at the time of the examination – or pass
the Level 2 practical within the Method exam
Basic Examination Both systems follow the same pattern – all questions are multiple
choice and all cover:
· Questions on the certification system (for example SNT-TC-1A/CP18910
or PCN Gen).
·
Product Technology
·
Other NDT Methods at Level 2
Variation:
PCN questions on its General document allow use of the document; ASNT
questions do not.
PCN only asks questions on four methods at Level 2 including
the method being examined (and if you hold a PCN Level 2 you are exempt
those questions relating to the Method held). ASNT, however, asks questions
in 11 NDT methods at Level 2 and no exemptions are allowed.
For the ASNT Basic exams you will be given about 135 multi choice
questions to be answered in 4 hours; for PCN there are a maximum of
100 multichoice questions to be answered in 3 hours.
Method Exam
ASNT covers all the following at Level 3:
Ultrasonic Testing*
Visual Testing*
Radiographic Testing*
Neutron Radiography Testing
Liquid Penetrant Testing*
Thermography/Infrared Testing
Magnetic Testing*
Leak Testing
Eddy Current Testing*
Vibration Analysis
Acoustic Emission
* PCN currently covers those methods identified with an asterisk,
plus Time of Flight Diffraction (TOFD) and, most recently, Alternating
Current Field Method (ACFM). Additionally, any PCN Method exams may
be broken down into sectors which maybe examined separately at Level
3. For example, as stated earlier, ASNT only examines in UT whereas
PCN Level 3 UT would be castings, welds, wrought products, axle testing
or time of flight.
Further, PCN requires a Specific test and a Practical test (the writing
of a procedure) which are not required by the ASNT Level 3 programme.
The ASNT method paper has 90 questions for (MT, PT and VT) and 130
questions for the other Methods; the PCN Method paper is divided into
general – 30 questions, Specific 20 questions and the drafting
of at least one procedure (plus the Level 2 practical exam if not already
held).

Employer Based Level 3 Exams
ASNT publishes a Recommended Practice SNT-TC-1A for the Employer to
establish a Company Written Practice as to how the Company trains its
NDT Personnel. The current issue is 2001, although it is not unusual
for a Company to quote the ’96 or ’92 version. Employer
based certification is only valid through the requirements of the Written
Practice and provides certification to Levels 1, 2 and 3 to the specific
products and Procedures of the Employer. Please note that Company Level
3 to a Written Practice based on SNT-TC-1A is not to be confused with
ASNT NDT Level 3 already described under Central Certification.
SNT-TC-1A
A Company Level 3 exam will follow the requirements of the Written
Practice, which will be based on SNT-TC-1A as follows:
Basic Examination (required only once when more than
one method examination is taken):
15 questions relating to understanding the SNT-TC-1A
document.
20 questions relating to applicable materials, fabrication and
product technology.
20 questions that are similar to publishes Level 2 questions
for other appropriate NDT methods.
Method Examination (for each method):
30 questions relating to fundamentals and principles
that are similar to published ASNT Level 3 question for each
method.
15 questions relating to application and establishment of techniques
and procedures that are similar to the published ASNT level 3
question for each method.
20 questions relating to capability for interpreting codes, standards
and specifications relating to the method.
Specific Examination (for each method):
20
questions relating to specifications, equipment, techniques
and procedures applicable to the employer’s product(s)
and methods employed and to the administration of the
employer’s
written practice.
The employer may delete the specific examination
if the candidate has a valid ASNT Level 3 certificate
in the method and if documented
evidence of experience exists, including the preparation
of procedures to codes, standards, or specifications
and the evaluation
of test results. Note there is no practical exam here or indeed a requirement to hold
a Level 2 practical.

If after all that
you fancy going for Level 3 then first of all you must decide if you
are going to put the
effort in – there are no minimum requirements for attending a Training
Course prior to sitting Level 3 exams – but it can’t be
recommended to take the examination without some preparation.
There are a wide range of texts prepared by eminent NDT technologists
from around the world which can be used as resource material, as well
as an increasing number of trainers accredited to provide training
at Level 3.
You need to be prepared to spend a bit too, here is
a rough estimate of costs:
a) Likely
Exam fee (based on 2005 fees for new candidates) Entry fee £300
Each exam £200
Lets say you will take Basic £200
MT £200
UT £200
Plus Entry Fee £300
Non ASNT member fee £ 55
Total for two methods say £955
b) Books: Basic Level 3 Study Guide
Product Technology Book
Major cover all texts
Each Method: Level 3 Study Guide
Major Method Texts
Question & Answer Book
For Basic, MT, UT – say £1000
c) Training - say
1 x 5 days for each exam plus
1 x 5 days review in March 2004
4 weeks at say £2-3000
d) Ball park figure say £5000 to cover Basic, MT and UT
