TEST PROCEDURES...
Approved procedures for "MT" are formulated from
analysis of the test specimen or article, review of its past history, experience
on like or similar specimens, and information available concerning
discontinuities in similar articles. It is the responsibility of personnel
conducting the test to ensure that test procedures are adequately performed, and
that the test objective is accomplished.
TEST OBJECTIVE...
The test objective of Magnetic Particle Inspection is to
ensure product reliability by providing a means of:
- a. Obtaining a visual image related to a discontinuity in or at the
surface of the material being tested.
- b. Disclosing the nature of the discontinuity without impairing the
material being tested.
- c. Separating acceptable and unacceptable material in accordance with
predetermined standards.
No test is successfully completed until an
evaluation of the test results is made. Evaluation of test procedures and
results requires understanding of the test objective as well as a knowledge of
the manufacturing processes that were involved.
PERSONNEL...
It is imperative that personnel responsible for "MT" be
trained and highly qualified with a technical understanding of the test
equipment and materials, the item under test, and the test procedures. To make
optimum use of "MT", personnel conducting tests must continually keep abreast of
new developments. There is no substitute for experience and knowledge. All
Tubi Tak personnel are certified in compliance with
SNT-TC-1A. |
