29、Practice E29.11. Ultrasonic Test11.1 Ingots shall be inspected ultrasonically by the methodsdescribed in 11.1.1 and 11.1.2 unless otherwise agreed uponbetween the manufacturer and the purchaser.11.1.1 StandardizationThe test shall be conducted in ac-cordance with Practice E114. The search unit shall
30、 be alongitudinal beam transducer, operated at a maximum fre-quency of 214 MHz using a suitable couplant with the piecebeing tested. The search unit shall be standardized on a testblock, setting the back reflection equal to 100 %. The test blockshall be of the same approximate diameter and surface c
31、ondi-tion as the ingot. Standardization is required before theinspection begins on the ingot.11.1.2 Unless otherwise approved by the purchaser, thereference standard shall consist of an ingot section containingtwo 0.093-in. 2.4-mm diameter holes, one of which shall beradially located at the approxim
32、ate ingot center, the other at theapproximate mid-radius position. These drilled holes shallterminate at a plane (normal to the longitudinal ingot axis)located 0.5 in. 12 mm below the ingot end face. Duringcalibration, the two reference holes should line up with thebeam, with the mid-radius hole far
33、thest from the search unit.Then the complete length of the ingot shall be inspected. Twotraverses shall be made along the length of the cylindrical ingotsurface 90 degrees apart. Additional traverses shall be made ifthe entire ingot is not adequately inspected by this procedure.Remove defect indicat
34、ions observed that exceed that of thereference standard. If the back reflection is between 50 and95 %, increase the gain to bring back reflection up to 100 %and inspect the trace indication to observe any internal reflec-tions greater than the indication from the reference standard.Again, remove any
35、 such defects. Following such amplitudeadjustment and inspection, recalibrate the search unit on thetest block. Note the position of all lesser defects and reportthem to the purchaser along with the ingot number.12. Inspection12.1 The manufacturer shall inspect the material covered bythis specificat
36、ion prior to shipment. If so specified on thepurchase order, the purchaser or his representative may witnessthe testing and inspection of the material at the place ofmanufacture. In such cases, the purchaser shall state in hispurchase order which tests he desires to witness. The manu-facturer shall
37、give ample notice to the purchaser as to the timeand place of the designated tests. If the purchasers represen-tative is not present at the time agreed upon for the testing, themanufacturer shall consider the requirement for purchasersinspection at place of manufacture to be waived.12.2 The manufact
38、urer shall afford the inspector represent-ing the purchaser, without charge, all reasonable facilities tosatisfy him that the material is being furnished in accordancewith this specification. This inspection shall be conducted so asnot to interfere unnecessarily with the operation of the works.13. R
39、ejection13.1 Rejection for failure of the material to meet thisspecification shall be reported to the manufacturer within 60calendar days from the receipt of the material by the purchaser.Unless otherwise specified, rejected material may be returnedto the manufacturer at the manufacturers expense, u
40、nless thepurchaser receives, within three weeks of the notice ofrejection, other instructions for disposition.14. Referee14.1 In the event of disagreement between the manufacturerand the purchaser on the conformance of the material to therequirements of this specification or any special test specifi
41、edby the purchaser, a mutually acceptable referee shall performthe tests in question. The results of the referees testing shall beused in determining conformance of the material to thisspecification.15. Certification15.1 A producers or suppliers certification shall be fur-nished to the purchaser tha
42、t the material was manufactured,sampled, tested, and inspected in accordance with this speci-fication and has been found to meet the requirements. A reportof the test results shall be furnished.16. Packaging and Marking16.1 Each ingot shall be metal die stamped on the top withthe manufacturers ingot
43、 number. Each box or skid shall belegibly and conspicuously marked or tagged with the followinginformation:16.1.1 Order or contract number,16.1.2 Name of material,16.1.3 Grade,16.1.4 Ingot number,16.1.5 Nominal diameter,16.1.6 Gross, net, and tare weights, and16.1.7 ASTM specification number.16.2 In
44、gots shall be boxed or banded on skids in such amanner as to assure safe delivery to their destination whenproperly transported by any common carrier.17.
