This standard is subject to revision at any e248 by the responsible technical committee and must be reviewed every? Note 1—Use of flat-surface reference blocks may not be suitable for cylindrical materials 3. G—Hole bottom must be?
Ee428 cases of materials that are acoustically transparent to the extent that this requirement cannot be satis? Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material.
At frequencies such as 5. The curve may vary when the examination is performed at other frequencies with different diameter search units and different water path distances or if a contact test method is used.
Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material. With the amplitude from the? Serial numbers are important when comparing sets of blocks to their respective response curves and to other sets of blocks.
Checking Ultrasonic Response Characteristics 8.
Link to Active This link will always route to the current Active version of the standard. The e248 characteristics of the hole may be established by evaluating plastic replicas. It is recommended that blocks fabricated as sets be compared with each other to determine their relative ultrasonic-response characteristics.
See Reference 1 for area-amplitude limitations at other frequencies and transducer diameters. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The curve may vary when the test is performed at other frequencies with different diameter search units and different water-path distances or if a contact test method is used. Last previous edition E — The asm blocks described r428 suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods.
The examination instruments, frequency, and search unit used in the evaluation of the raw asfm intended for the fabrication of the reference blocks shall be comparable to that used in the examination of the production material.
Also see Reference 2 for cautions regarding use of standard blocks for test standardizations. The replica shall indicate that the hole bottom is?

This practice shall in no way preclude the specification or addition of any supplemented requirements as deemed necessary for the specific application. On samples that are to have FBHs smaller than 3?
For record purposes, the replica may be projected on a comparator screen and photographed as shown in Fig. Note 2—Practice E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
NOTE 2—This practice wstm be used to produce blocks with? Summary of Practice 4. Originally published as E — Checking Physical Characteristics 7.
ASTM E428 – 08(2013)
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. D—Hole diameter tolerance Careful attention must be given to the squareness of corners of the cutter, the slightest radius reduces the re?
Due to possible edge build-up during the plating process, this tolerance applies only to the area exclusive of that within 1? The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
