Whenever test results are obtained from both full-size and machined specimens and they differ, the test resultsfrom the full-size specimens shall prevail.
Each test specimen shall be flat-tened in a press.The flattened area shail be at least 4 in. [100mm] in length. A filattened test specimen shall allow a mi-crometer caliper set at three (3) times the wall thickness to passfreely over the flattened area. The flattened areas of the testspecimen shall be inspected for surface defects.Electromagnetic (Eddy Current) Test—Testing shallfollow the procedures in Practice E 243, except for the deter-mination of”endeffect.”
Notchdepth standards shall be rounded to thenearest 0.001 in. [0.025 mm]. The notch depth tolerance shallbe 0.0005 in.[0.013 mm].Drilled hole standards shall be rounded to thenearest 0.001 in. (0.025 mm).The drilled hole tolerance shallbe 0.0005 in. [0.013 mm].
Alternatively,at the option of the manufacturer,using speed-insensitive eddy current testing units that areequipped so that a percentage of the maximum imbalancesignal can be selected, a maximum imbalance signal of 0.3 %shall be used.Tubes that do not activate the signaling device ofthe eddy current tested shall be considered as conforming to therequirements of this test.Tubes with discontinuities indicatedby the testing unit are permitted, at the option of the manufac-turer,to be reexamined or retested to determine whether thediscontinuity is cause for rejection. Signals that are found tohave been caused by minor mechanical damage,soil,ormoisture shall not be cause for rejection of the tubes providedthe tube dimensions are still within prescribed limits and thetune is suitable for its intended application.The test method used shall permiteasy visual detection of any leakage or by pressure differential.Any evidence of leakage shall be cause for rejection.The test method used shall permiteasy visual detection of any leakage or by pressure differential.Any evidence of leakage shall be cause for rejection.When the product is specified to meet the requirementsof the ASME Boiler and Pressure Vessel Code, the certificationrequirements of Specification B 251 or B 251M are mandatory.ASTM B466 pdf download.
