For example, the identi? Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material. The acoustic noise level from the material is not to be confused with inherent electrical instrument noise often observed when the system sensitivity is adjusted to its maximum level range. This practice, however, must not be confused with, nor does it supersede Practice Especi?
Note 1—Use astn flat-surface reference blocks may not be suitable for cylindrical materials 3. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.
This practice shall in no way preclude the speci? Under no circumstances may the FBH be altered to change the ultrasonicresponse characteristics of the reference block. It is the responsibility of the user of ast, standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior asttm use. The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods.
NOTE 2—This practice may be used to produce blocks with?

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Asym, consideration should be given to the operating characteristics of the search unit and instrument generally available from the equipment manufacturer when evaluating the astk curves from the reference blocks.
Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel wstm. Current edition approved July 10, Also see Reference 2 for cautions regarding use of standard blocks for test standardizations. Without changing any test parameters, the ultrasonic response from the remaining blocks with both shorter and longer distances are plotted on the response curve.
Where several sets and types of blocks are being used, a serial number identi?
D—Hole diameter tolerance Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material. Note 2 — Practice E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response. 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.
Checking Physical Characteristics 7. This practice shall in no way preclude the specification or addition of any supplemented requirements as deemed necessary for the specific application.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
If the ultrasonic-response characteristics are to be established by immersion techniques, the drilled? An adequate air gap must be maintained at the hole bottom. 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.
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.

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.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? A superscript epsilon e indicates an editorial change since the last revision or reapproval. Serial numbers are important when comparing sets of blocks to their respective response curves and to other sets of blocks.
