ASTM E – 00_百度文库

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. Current edition approved July 10, Note 2 — Practice E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response. Without changing any test parameters, the ultrasonic response from the remaining blocks with both shorter and longer distances are plotted on the response curve.

Careful attention must be given to the squareness of corners of the cutter, the slightest radius reduces the re? D—Hole diameter tolerance It is the responsibility of the user of this standard atsm 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. This practice shall in no way preclude the specification or addition of any supplemented requirements as deemed necessary for the specific application. This is particularly desirable in the cases of sets containing? Due to possible edge build-up during the plating process, this tolerance applies only to the area exclusive of that within 1? Comparison test at other frequencies or with uncalibrated instruments will not necessarily give the same relationships shown in this practice.

With the amplitude from the? 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. Unlike this practice, Practice E has requirements for evaluation relative to a specified standard target.

ASTM E428 – 08(2013)

The physical characteristics of the hole may be established by evaluating plastic replicas. The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods.

For example, the identi? Under no circumstances may the FBH be altered to change the ultrasonicresponse characteristics of the reference block. Link to Active This link will always route to the current Active version of the standard. In cases of materials that are acoustically transparent to the extent that this requirement cannot be satis? Block sets conforming to customary commercial practice are grouped as follows: Additional supplemental requirements may be needed when using this practice to fabricate reference blocks from other types of materials or with larger diameter holes.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Checking Physical Characteristics 7. The following machining sequence is recommended: This practice shall in no way preclude the speci? 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.

Additional procedures and controls may be required when fabricating f428 blocks from other than carbon or alloy atsm material. 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.

Last previous edition E — Serial numbers are important when comparing sets of blocks to their respective response curves and to other sets of blocks. At frequencies such as 5. Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material.

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. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Note 2—Practice E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response.

NOTE 2—This practice may be used to produce blocks with? The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods.

A superscript epsilon e indicates an editorial change since the last revision or reapproval.
