U.T. Procedure
Sheet 4 of 10

Ultrasonic standard reference blocks, often called test block, are used in
ultrasonic testing not only to calibrate the ultrasonic equipment but
principally to evaluate the discontinuity indication.
Standardization means two things it verifies that the instrument/ probe
combination is performing as required calibration it establishes a sensitivity
(or grain) level.
Evaluation of discontinuities within a piece is accomplished by comparing
the indications from them with the indication from an artificial discontinuity
of known size, at the same depth in a standard reference block of the same
material to be tested. DAC calibration curve shall be draw as follow.

1. To make calibration block as per appendix 2.

2. Find the hole that give the highest amplitude & set in 80% of the full screen
height.
3. Mark the peak of indication from 1/4, 1/2, 3/4 & connect all point to each
other for drawing of distance amplitude corrective on curve.

5.3- Test Scope

According to welding & NDT plan (100%) UT.
See drawings No. AC01-118-09-00

6- Acceptance Standard
As per ASME code SEC. VIII Div.1 appendix 12 and project specification.

7- Documentation
Original certificates remain in quality department.
One copy to Namvaran Co.

8- Sound Beam Propagation

For sound beam propagation see appendix 4.

9- Reporting
Operator/ inspector shall provide a test report (appendix 1) after performing each
test and send to client authorized inspector for approval.

10- Appendix
See appendix 1, 2, 3, 4, 5, 6
Personal Qualification
The qualification of NDE personnel shall be in accordance with their employer’s
written practice which must be in accordance with one of SNT-TC-1A , ANSI/ASNT
CP-189 , national or international central certification progress.
