For example, the identi? The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo e4228 methods. Link to Active This link will always route to the current Active version of the standard.

Last previous edition E — The physical characteristics of the hole may be established by evaluating plastic replicas. Additional supplemental requirements may be needed when using this practice to fabricate reference blocks from other types of materials or with larger diameter holes. Unlike this practice, Practice E has requirements for evaluation relative to a specified standard target. It is the responsibility of the user of this standard to establish appro- 1 This practice is under the jurisdiction of ASTM Committee E07 on Nondestructive Testing and is the direct responsibility of Subcommittee E This practice shall in no way preclude the specification or addition of any xstm requirements as deemed necessary for the specific application.

Without changing any examination parameters, the ultrasonic response from the remaining blocks with both smaller and larger size re? Under no circumstances may the FBH be altered to change the ultrasonicresponse characteristics of the reference block. Checking Ultrasonic Response Characteristics 8. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

NOTE 2—This practice may be used to produce blocks with? Originally published as E — 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. Current edition approved July 10, Summary of Practice 4. 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.

For record purposes, the replica may be projected on a comparator screen and photographed as shown in Fig. 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.

Comparison test at other frequencies or with uncalibrated instruments will not necessarily give the same relationships shown in this practice. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at awtmfaxor service astm. Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material.

A number in parentheses indicates the year of last reapproval.

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.
