ASTM E428 – 08(2013)

Checking Ultrasonic Response Characteristics zstm. 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.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Summary of Practice 4. Due to possible edge build-up during the plating process, this tolerance applies only to the area exclusive of that within 1? E482 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.

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. The machined counterbore may be omitted if this plugging technique is used.

Unlike this practice, Practice E has requirements sstm evaluation relative to a specified standard target. Active view current version of standard. 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.

Active view current version of standard Translated Standard: 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. Link to Active This link will always route to the current Active version of the standard. Without changing any test parameters, the ultrasonic response from the remaining blocks with both shorter and longer distances are plotted on the response curve.

The reference e482 described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods. 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.

It is recommended that blocks fabricated as sets be compared with each other to determine their relative ultrasonic-response characteristics. Serial numbers are important when comparing sets of blocks r428 their r428 response curves and to other sets of blocks.

Additional supplemental requirements may be needed when using this practice to fabricate reference blocks from other types of materials or with larger diameter holes.

Careful attention must be given to the squareness of corners of the cutter, the slightest radius reduces the re? A number in parentheses indicates the year of last reapproval. Originally published as E — Note 1—Use of flat-surface reference blocks may not be suitable for cylindrical materials 3. Block sets conforming to customary commercial practice are grouped as follows: 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.

An adequate air gap must be maintained at the hole bottom. Without changing any examination parameters, the ultrasonic response from the remaining blocks with both smaller and larger size re? At frequencies such as 5.

Note 2—Practice E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response. This is particularly desirable in the cases of sets containing?
