The values given in parentheses are mathematical conversions to SI units that are provided for information f428 and are not considered standard. Originally published as E — It is recommended that blocks fabricated as sets be compared with each other to determine ashm relative ultrasonic-response characteristics.
The examination instruments, frequency, and search unit used in the evaluation of the raw material intended for the fabrication of the reference blocks shall be comparable to that used in the examination of the production material.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and zstm not considered standard. On samples that are to have FBHs smaller than 3? Last previous edition E — Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Note 1 — Use of flat-surface reference blocks may not be suitable for cylindrical materials 3 2.
In cases of materials that are acoustically transparent to the extent that this requirement cannot be satis? An adequate air gap must be maintained at the hole bottom.
Therefore, consideration should be given to the operating characteristics of the search unit and instrument generally available from the equipment manufacturer when evaluating the response curves from the reference blocks. Unlike this practice, Practice E has requirements for evaluation relative to a specified standard target. At frequencies such as 5. Careful attention must be given to the squareness of corners of the cutter, the slightest radius reduces the re?
If the ultrasonic-response characteristics are to be established by immersion techniques, the drilled? Active view current version of standard. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
With the amplitude from the? This is particularly desirable in the cases of sets containing? Generally, nickel plating to a maximum thickness of 0.

It must be recognized however that there are limitations on the size hole that may be replicated and evaluated. This practice shall in no way preclude the specification w428 addition of any supplemented requirements as deemed necessary for the specific application.
Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material. However, the coating must not signi?
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. Unlike this practice, Practice E has requirements for evaluation relative to a speci?

Due to possible edge build-up during the plating e28, this tolerance applies only to the area ast, of that within 1? This practice, however, must not be confused with, nor does it supersede Practice Especifically governing the fabrication and evaluation of T6 aluminum alloy ultrasonic standard reference blocks.
Note 2 — Ee428 E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response. Without changing r428 examination parameters, the ultrasonic response from the remaining blocks with both smaller and larger size re? Summary of Practice 4. Checking Physical Characteristics 7.

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.
The machined counterbore may be omitted if this plugging technique is used. Also see Reference 2 for cautions regarding use of standard blocks for test standardizations.
