PDI UT-8 Revision F
• Changes made to further explain the use of Tables E1 & E2 and to provide criteria on selecting search units with configurations not addressed in the tables
![Page 7: PDI UT-8 Revision F and PDI UT-10 Revision C, Review of … › docs › ML0622 › ML062230427.pdf · 2012-11-21 · PDI UT-8 Revision F Ø4.00 Ø6.86=D2 Ø5.45 = D1 Lower Bound](https://reader034.vdocuments.mx/reader034/viewer/2022042410/5f28268f41ad337f6063e4dc/html5/thumbnails/7.jpg)

PDI UT-8 Revision F
• Tables E1 & E2 rounded to one decimal place and a 1mm tolerance allowed for Metric to English conversions
![Page 8: PDI UT-8 Revision F and PDI UT-10 Revision C, Review of … › docs › ML0622 › ML062230427.pdf · 2012-11-21 · PDI UT-8 Revision F Ø4.00 Ø6.86=D2 Ø5.45 = D1 Lower Bound](https://reader034.vdocuments.mx/reader034/viewer/2022042410/5f28268f41ad337f6063e4dc/html5/thumbnails/8.jpg)

PDI UT-8 Revision F
• Clarify the intent that both calculations need to be performed to fully assess the need for contoured search units
![Page 9: PDI UT-8 Revision F and PDI UT-10 Revision C, Review of … › docs › ML0622 › ML062230427.pdf · 2012-11-21 · PDI UT-8 Revision F Ø4.00 Ø6.86=D2 Ø5.45 = D1 Lower Bound](https://reader034.vdocuments.mx/reader034/viewer/2022042410/5f28268f41ad337f6063e4dc/html5/thumbnails/9.jpg)

PDI UT-8 Revision F
• Moved the signal to noise ratio evaluation into the calibration section– Signal to noise from a reference reflector has not
been demonstrated as an affective basis for flaw detection. However is a valuable assessment of system performance
![Page 10: PDI UT-8 Revision F and PDI UT-10 Revision C, Review of … › docs › ML0622 › ML062230427.pdf · 2012-11-21 · PDI UT-8 Revision F Ø4.00 Ø6.86=D2 Ø5.45 = D1 Lower Bound](https://reader034.vdocuments.mx/reader034/viewer/2022042410/5f28268f41ad337f6063e4dc/html5/thumbnails/10.jpg)

Summary of Changes to PDI-UT 8 Rev. F
• Changes made mostly for clarification purposes
• Tables E1 & E2 rounded to one decimal– No affect on original qualification– All transducers used for procedure qualification meet
the requirements of these tables
