G—Hole bottom must be? Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material. Therefore, consideration should be given to the operating characteristics of the search unit 4e28 instrument generally available from the equipment manufacturer when evaluating the response curves from the reference blocks. See Reference 1 for area-amplitude limitations at other frequencies and transducer diameters.
Without changing any examination parameters, the ultrasonic response from the remaining astj with both smaller and larger size re? Unlike this practice, Practice E has requirements for evaluation relative to a specified standard target. Where several sets and types of blocks are being used, a serial number identi? Current edition approved July 10, At frequencies such as 5. NOTE 2—This practice may be used to produce blocks with? The values given in parentheses are mathematical conversions to D428 units that are provided for information only and are not considered standard.

The replica shall indicate that the hole bottom is? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
On samples that are to have FBHs smaller than 3? Under no circumstances may the FBH be altered to change the ultrasonicresponse characteristics of the reference block. Serial numbers are important d428 comparing sets of blocks to their respective response curves and to other sets of blocks.
Comparison test at other frequencies or with uncalibrated instruments will not necessarily give the same relationships shown in this practice. Also see Reference 2 for cautions regarding use of standard blocks for test standardizations.

Additional supplemental requirements may be needed when using this practice to fabricate reference blocks from other types of materials or with larger diameter holes. With the amplitude from the?
Note 1—Use of flat-surface reference blocks may not be suitable for cylindrical materials 3. The physical characteristics of the hole may be established by evaluating plastic replicas. If the ultrasonic-response characteristics are to be established by immersion techniques, the drilled? The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods. This asm shall in no way preclude the specification or addition of any supplemented requirements as deemed necessary for the specific application.
The following machining sequence is recommended: Generally, nickel plating to a maximum thickness of 0.
An adequate air gap must be maintained at the hole bottom.
